Introduction: What Are Custom CNC Bearing Parts?
If you’ve ever worked with industrial machinery, you know that bearings are the unsung heroes keeping everything running smoothly. These small but critical components reduce friction between moving parts, ensuring precision operation and extending equipment lifespan. But when standard off-the-shelf bearings don’t meet your specific requirements, custom CNC bearing parts become essential.
At XiamenGoldCattle, we’ve been perfecting the art of CNC bearing machining for over 26 years. As a national high-tech enterprise, we understand that every application has unique demands that standard bearings can’t always satisfy. That’s where our custom CNC machining expertise comes in.
What Types of CNC Bearing Parts Can Be Customized?
Bearing Outer Rings
The outer ring forms the housing for the bearing assembly. We machine outer rings with precise roundness, concentricity, and surface finish to ensure proper fit and rotation.
Bearing Inner Rings
Inner rings require even tighter tolerances since they directly interface with shafts. Our CNC turning centers achieve the high precision needed for proper shaft engagement.
Bearing Housings / Seats
These critical components position and secure bearings within machinery. We customize bearing housings for OEM equipment across various industries.
Bearing Cages / Retainers
Cages maintain proper spacing between rolling elements. Our CNC milling capabilities create intricate cage designs for optimal performance.
Bearing Rollers / Balls
For specialized applications, we manufacture custom rolling elements with precise dimensions and surface treatments.
Miniature Bearing Parts
Our micro-machining capabilities produce tiny bearing components for medical devices, aerospace, and precision instruments.
Materials for CNC Bearing Parts
Stainless Steel (440C / 304 / 316L)
- 440C: Offers excellent hardness and wear resistance after heat treatment
- 304: Good corrosion resistance for general applications
- 316L: Superior corrosion resistance for marine and medical environments
Chrome Steel / Alloy Steel (GCr15)
The industry standard for high-performance bearings, offering excellent fatigue life and wear resistance.
Aluminum 6061 / 7075
Lightweight options for applications where weight reduction is critical, such as aerospace components.
Brass / Bronze
Natural lubricity makes these ideal for low-speed, high-load applications where maintenance access is limited.
Titanium
Offers exceptional strength-to-weight ratio and corrosion resistance for demanding environments.
Engineering Plastics (PEEK / Delrin)
For applications requiring corrosion resistance, electrical insulation, or chemical compatibility.
CNC Machining Processes Used for Bearing Parts
CNC Turning
Our high-precision CNC lathes achieve the concentricity and roundness critical for bearing raceways. We use live tooling to add features like slots, holes, and threads in a single setup.
CNC Milling
For bearing housings and cages, our 3-axis and 4-axis mills create complex geometries with tight tolerances.
Multi-axis Machining
Our 5-axis machining centers allow us to produce complex bearing components with fewer setups, improving accuracy and efficiency.
Precision Grinding
Achieving surface finishes down to Ra 0.1μm for bearing raceways and critical surfaces.
Heat Treatment & Hardening
We partner with certified heat treatment facilities to ensure proper material properties for bearing applications.
Surface Treatment
Options include:
- Electroplating (chrome, nickel, zinc)
- Passivation for stainless steel
- Phosphating for improved lubrication
- PTFE coating for self-lubrication
