Product Range and Application Fit

Self-aligning ball bearings are designed to accommodate shaft misalignment and deflection, making them ideal for applications where alignment is difficult to maintain. Our series are engineered for different load and speed conditions:

Engineering Value and Customization

We understand that every application has unique requirements. Our engineering team works with you to select the right series, material, and internal clearance. We can customize:

• Bore size (cylindrical or tapered)
• Sealing options (open, ZZ, 2RS)
• Material (chrome steel GCr15, stainless steel 440C, or other)
• Lubrication (grease type and quantity)
• Noise and vibration levels for specific applications

Quality Assurance and Testing

Quality is built into every stage. We perform inspections after each process, and finished bearings undergo full inspection according to customer requirements and international standards. Our testing includes dimensional accuracy, hardness, surface finish, noise, and vibration. We also conduct rotation flexibility checks to ensure smooth operation.
