Holzmann offers a comprehensive range of woodworking machinery designed for workshops, craftsmen and professional users. Among these machines, drum sanders make it possible to sand large wooden surfaces evenly while accurately controlling the thickness of the workpiece.

The Holzmann ZS970P is a professional twin-drum sander offering a maximum sanding width of 970 mm. Its two-drum design makes it possible to perform coarse and fine sanding successively during a single pass.

This category includes spare parts for the Holzmann ZS970P drum sander for maintaining and repairing your machine: gears, belts, bearings, conveyor components, drive parts, mechanical parts and electrical components.

Spare Parts for Holzmann ZS970P

A drum sander contains numerous mechanical components that are subjected to considerable loads during operation.

The two sanding drums, conveyor system, transmission mechanisms, gears, bearings and adjustment components work together to ensure smooth workpiece feeding and consistent sanding results.

Over time, some of these components may naturally wear and require replacement.

Having access to Holzmann ZS970P spare parts allows the machine to be repaired and its service life extended without having to replace the complete sander.

Parts for ZS970P Twin-Drum Sander

One of the main features of the Holzmann ZS970P is its twin-drum sanding system.

This configuration allows two successive sanding operations to be performed during a single pass. Abrasives with different grits can therefore be installed to carry out an initial heavier sanding operation followed by a finer finishing pass.

This design requires various mechanical components to ensure correct drum rotation, drive and adjustment.

Depending on availability, our range may include:

• drive gears;

• bevel gears;

• drive belts;

• pulleys;

• bearings;

• shafts;

• axles;

• conveyor components;

• transmission parts;

• adjustment components;

• switches;

• electrical components;

• mechanical parts.

Our selection is progressively expanded according to the spare parts available for the ZS970P.

Gears for Holzmann ZS970P

Gears transmit movement between the different mechanical components of the machine.

A Holzmann ZS970P gear can gradually develop worn teeth or excessive play, or become damaged following a blockage or excessive mechanical load.

A damaged gear can cause unusual noises, irregular operation or prevent the affected mechanism from operating correctly.

The parts available for this machine may include bevel gears for the Holzmann ZS970P drum sander.

Before ordering, it is essential to compare the spare part reference and item number with the exploded parts diagram for your machine.

Drive Belts and Transmission System

Drive belts transmit power from the motor to the different mechanical components of the sander.

Over time, a Holzmann ZS970P drive belt can stretch, crack, wear or eventually break.

A damaged belt can cause poor power transmission, vibrations, abnormal noises or incorrect operation of the sanding drums.

When replacing a belt, it is also advisable to inspect the condition of the pulleys and other transmission components.

Installing a new belt on a heavily worn or misaligned pulley can result in premature wear of the replacement belt.

Bearings and Mechanical Parts for ZS970P

Bearings are essential for the numerous rotating components of the drum sander.

They help reduce friction while correctly supporting rotating shafts and axles.

A worn bearing may become noisy, overheat, develop excessive play or cause vibrations.

When these symptoms appear, the affected component should be inspected promptly to prevent excessive wear from damaging other mechanical parts.

Our range of ZS970P spare parts may therefore include different bearings, shafts, supports and other components required to repair the machine's mechanisms.

Conveyor Parts for Holzmann ZS970P

The conveyor is a fundamental part of a drum sander.

It moves the wooden workpiece beneath the two sanding drums at a consistent speed.

The Holzmann ZS970P features an adjustable feed speed, allowing the workpiece movement to be adapted to the sanding operation being performed.

A feed speed that is too high or too low can affect the sanding result. Correct conveyor operation is therefore essential for obtaining a consistent finish.

If a feed problem occurs, several components should be inspected, including the conveyor belt, drive system, gears, rollers, conveyor motor, transmission and speed control system.

Conveyor Motor and Drive System

The conveyor has its own drive system, allowing the workpiece feed rate to be adjusted independently.

A conveyor feed problem therefore does not necessarily mean that the main sanding motor is faulty.

If the conveyor stops working, moves intermittently or lacks power, the complete conveyor drive system should be inspected.

Possible causes include the conveyor motor, electrical connections, transmission components and feed speed control system.

Accurate diagnosis is recommended before ordering an electrical or mechanical replacement component.

Twin Drums for Coarse and Fine Sanding

The Holzmann ZS970P is designed to provide efficient sanding through its two sanding drums.

Abrasives with different grit sizes can be fitted to achieve two sanding stages during a single pass.

The first drum can be equipped for greater material removal, while the second drum can be used to achieve a finer finish.

To maintain the performance of the machine, both drums must rotate smoothly and their mechanical components must remain correctly adjusted.

Vibrations or irregular operation should therefore lead to an inspection of the bearings, drive system and fastening components before continuing to use the machine.

Abrasives for Holzmann ZS970P Drum Sander

Abrasives are essential consumables for the operation of the drum sander.

The ZS970P can use 150 mm wide abrasive rolls, which are cut and fitted around the sanding drums.

Different grit sizes can be selected depending on the required sanding result.

A coarser grit provides greater material removal, while a finer grit is generally used to improve the surface finish.

Using suitable abrasives in good condition helps maintain sanding quality and reduces unnecessary stress on the machine.

Why Replace a Worn ZS970P Part?

A mechanical fault does not necessarily mean that the complete drum sander needs to be replaced.

Many components of the Holzmann ZS970P can be replaced individually.

A damaged gear, drive belt, bearing, pulley, conveyor component or electrical part can be replaced to restore the machine to proper working condition.

This is particularly valuable on a machine of this type, designed for regular sanding and thickness-calibrating work on large wooden workpieces.

How to Identify Your Holzmann ZS970P Spare Part

Before ordering, it is important to accurately identify the required component.

The Holzmann ZS970P exploded parts diagram allows the various machine components to be located and their item numbers identified.

We therefore recommend locating the required part on the exploded diagram and comparing its item number and reference with the information provided on our product page.

The manufacturer's spare part reference is also particularly useful when available.

For electrical components, also compare the voltage, power rating, connections and markings shown directly on the original component.

ZS970P 230 V and 400 V: Check Your Version

The Holzmann ZS970P is available in 230 V and 400 V versions.

This difference is particularly important when ordering electrical components.

A motor, switch or other electrical component intended for a 230 V machine is not automatically compatible with a 400 V version, and vice versa.

For mechanical parts, it is also essential to check the reference and item number indicated on the product page.

Never rely solely on the visual appearance of a spare part.

Compatibility with Holzmann ZS640P

The Holzmann ZS640P and ZS970P belong to the same family of drum sanders, and some spare parts may be shared between the two models.

However, compatibility is not systematic.

The ZS640P has a different working width, which means that some mechanical components may differ from those fitted to the ZS970P.

When a spare part is suitable for both models, this information should be specified on its product page.

Visual similarity between two components is not sufficient to guarantee interchangeability.

Check Compatibility Before Ordering

IMPORTANT: BEFORE PURCHASING, always check that your machine is included in the list of compatible machines provided on the spare part product page.

Not all parts shown in this category are necessarily compatible with every version or production year of the ZS970P.

Dimensions, mounting points, mechanical specifications and electrical characteristics may vary.

When this information is provided on the product page, also check the month and year of manufacture and the serial number of your machine.

For electrical components, always check whether your ZS970P is a 230 V or 400 V version.

Maintaining Your Holzmann ZS970P Drum Sander

A machine used regularly requires suitable maintenance to preserve its performance.

Dust generated during sanding should be efficiently removed using an appropriate dust extraction system.

It is also advisable to regularly inspect the condition of the abrasives, conveyor, drive belts, bearings and various drive components.

Unusual noises, excessive vibrations, irregular feed or a reduction in sanding quality should be treated as signs that the machine requires inspection.

Replacing a worn component promptly can often prevent damage to other parts.

Extend the Service Life of Your Holzmann ZS970P

The availability of spare parts for the Holzmann ZS970P drum sander makes it possible to maintain and repair this professional machine over the long term.

Gears, belts, bearings, conveyor components, transmission parts and electrical components can be replaced individually when required, often restoring correct operation without replacing the complete machine.

Our range of Holzmann ZS970P spare parts is progressively expanded to provide more solutions for maintaining and repairing your professional twin-drum sander.
