CNC Machined Black POM Plastic Bearings: A Lightweight Solution for Clean and Corrosion-Sensitive Applications
Traditional metal bearings are widely used in industrial equipment, but they are not always the best choice for environments requiring corrosion resistance, low weight, low noise, or non-metal solutions.
This CNC machined black POM plastic bearing combines precision polymer machining technology with a sealed bearing structure, providing smooth rotation performance and reliable operation for automation, cleanroom, food processing, and chemical equipment.
Unlike standard injection molded plastic bearings, CNC machining allows better dimensional control and customization flexibility for demanding industrial applications.
What Is a CNC Machined POM Plastic Bearing?
A CNC machined POM plastic bearing is a polymer bearing manufactured by precision machining POM (Polyoxymethylene) material into the inner and outer rings.
This bearing consists of:
- CNC machined black POM inner ring
- CNC machined black POM outer ring
- Nylon injection molded cage
- Stainless steel balls or glass balls
- Double-sided sealing structure
The combination of polymer materials and precision machining creates a lightweight bearing solution suitable for applications where metal bearings may cause limitations.

This advantage is especially valuable for:
- Medical equipment
- Laboratory equipment
- Precision automation
4. Flexible Ball Material Selection
Different applications require different rolling materials.
Stainless Steel Balls
Suitable for:
- General industrial applications
- Higher mechanical load requirements
- Standard automation equipment
Glass Balls
