Manufacturing Accumulation
Established in 2012, continuously investing in grinding and inspection capabilities.
Full-process in-house control from grinding to CMM inspection
Key processes are completed on our own production lines, with inspection data archived by batch. Customers can verify parameters by model or review records by batch.
Precision Grinding and Assembly Process
Automated control of the groove super-finishing and constant-temperature assembly processes to ensure raceway roundness and clearance consistency, optimized for low-noise and high-speed operation.
End-to-End Quality Inspection
Coordinate measuring machines, combined with roundness, roughness, and vibration testing, document every batch from incoming inspection to finished product sampling.
Scalable Capacity and Delivery
Multiple production lines operate in parallel with an annual capacity of over 5000 million units, supported by intelligent warehousing for order-based inventory and shipping.
Dual System Certification and Traceability
Process records and batch traceability under ISO 9001 and IATF 16949 standards support audit requirements for automotive and aerospace clients.
Micro-bearing specialized capabilities
Miniature bearing series covering inner diameters from 1 to 9mm, designed for low noise and compact size in medical devices and drone motors.
Four series covering 1–9mm to medium and large sizes.
Each series provides model numbers, precision grades, and load parameters to help engineers filter options before requesting a quote.
Configure by industry, select by operating conditions
Load, speed, and environmental conditions vary significantly across different application areas, necessitating corresponding adjustments in series selection and precision grades.
