608ZZ POM coated roller

Product Description

608ZZ POM Coated Roller for Sliding Door and Furniture Applications

This 608ZZ POM coated roller combines a standard deep groove ball bearing with a molded POM outer running surface. The finished roller measures 8 mm in bore diameter, 30 mm in outside diameter and 9 mm in overall width.

The internal bearing uses GCr15 bearing steel, while the outer surface is molded with POM. This construction provides a compact rolling component for applications where the bearing needs to work together with a plastic running surface.

The roller is particularly suitable for sliding wardrobe doors, furniture sliding systems, drawers, guide mechanisms and other compact rolling applications where controlled movement and reduced metal-to-metal contact are required.

BLH Bearing manufactures this coated roller as a complete bearing-and-wheel assembly and can also provide customized material and dimensional options for OEM projects.

Core applications of the wheel

Sliding Wardrobe Doors and Furniture Hardware

One of the key applications for this type of 608ZZ POM coated roller is sliding wardrobe door and furniture hardware.

Sliding wardrobe doors require compact rollers that can move repeatedly along a guide track without taking up excessive installation space. The 8 mm bore provides a practical mounting interface, while the 30 mm POM-coated outside diameter forms the running surface.

Compared with a bare steel bearing surface, the POM outer layer provides a plastic contact surface between the roller and the track. This makes the coated roller suitable for furniture applications where smooth movement, controlled rolling and reduced operating noise are important design considerations.

The same roller construction can also be adapted for:

Sliding wardrobe doors

Furniture sliding doors

Cabinet sliding systems

Drawer mechanisms

Guide rollers

Small sliding mechanisms

Light-duty track systems

Advantages of POM Material

POM Coating for the Running Surface

POM, also known as polyoxymethylene or acetal, is commonly used for precision plastic components that require good dimensional stability and wear resistance.

For a bearing roller, the outer material directly contacts the guide track, so material selection has an important effect on the operating characteristics of the complete roller.

The POM version offers:

Good dimensional stability

Wear resistance

Low-friction characteristics

A smooth plastic running surface

Reduced metal-to-metal contact

Consistent performance in precision molded components

For applications requiring different mechanical properties, BLH Bearing can also manufacture the coated roller using PA66 or another customer-specified material.

Material selection should be based on the actual load, track material, operating temperature, impact conditions and required service life.

Why use the 608ZZ?

Why Use a 608ZZ Bearing Inside the Coated Roller?

The 608 bearing is a widely used deep groove ball bearing size with an 8 mm bore. In this coated roller, the bearing provides the internal rolling mechanism while the molded POM layer creates the external wheel surface.

This combination allows the roller to perform two functions within one component:

608ZZ bearing → rotational support

POM outer layer → rolling contact with the track

This construction is useful when a project requires an 8 mm mounting bore and a larger 30 mm rolling diameter without using a separate metal wheel and bearing assembly.

Technology Selection

What Should You Check Before Ordering?

Selecting a coated bearing roller requires more than matching the bearing number. The complete roller needs to match the mechanical design of the application.

Bore Diameter

This roller has an 8 mm bore. Check the shaft, pin or mounting hardware before ordering.

Finished Diameter

The finished outside diameter is 30 mm, including the POM outer coating.

Width

The overall roller width is 9 mm. Make sure there is sufficient installation clearance.

Track Profile

This product has a rounded/flat outer running surface rather than a V-groove profile. The track should be compatible with the roller geometry.

Load

The stated load rating is 2.53 kN. The actual allowable load in a sliding-door or furniture mechanism should also consider the number of rollers, load distribution, installation condition and track structure.

Speed

The specified rotational speed is up to 30,000 rpm. Actual application speed should be evaluated together with load, lubrication, temperature and operating cycle.
