When standard bearings cannot meet your equipment requirements, our engineering team works with you to develop customized bearing solutions from initial concept and prototype evaluation to production delivery.
We evaluate your application requirements, drawings, samples, and technical specifications to recommend suitable bearing structures and manufacturing solutions.
From initial samples to validation builds, we support prototype development to help verify dimensions, performance, and compatibility before mass production.
We manufacture customized bearings based on specific project requirements, including special dimensions, configurations, materials, and performance requirements.
After approval, customized products can be transferred into stable production with controlled manufacturing processes and inspection procedures to ensure consistent quality.
Specializing in precision bearing manufacturing, we integrate R&D, precision processing, quality inspection, customized production, fast delivery and after-sales support to form a complete one-stop bearing manufacturing system. Equipped with high-precision production and testing equipment, our modern workshop realizes full in-house control from raw material processing and precision machining to finished product inspection and packaging. We provide standard bearing mass production and non-standard customization services, adapting to various working conditions for machinery, automation, new energy, medical and engineering industries. With one-on-one full-process service, we deliver stable, efficient and reliable one-stop bearing solutions for global customers.
Select bearings according to shaft and housing dimensions, load and speed, temperature, environment, clearance, sealing, and lubrication.
Match suitable bearing structures based on load type, speed, space limitations, accuracy, and environment. Considering radial/axial load-bearing capacity, friction coefficient, allowable temperature rise, and sealing method, we can help you narrow down the selection range.
Adapt to equipment from multiple industries, ranging from precision automation, robotics, medical instruments to conveying and packaging machinery. Provide supporting bearing solutions for special needs such as cleanliness, high speed, and corrosion prevention in different industries
Targeting harsh working conditions such as corrosive environments, high-speed operation, dust and water resistance, and high and low temperatures. Provide selection of stainless steel, ceramic, sealed, and maintenance free bearings。
Rotating shafts in motors, fans, and generators.
Reliable radial support and continuous operation.
Transmission components in power systems.
Compact mechanisms and high-speed motion.
Rotating assemblies under demanding conditions.
Fans, compressors, conveyors, and machinery.

Self-aligning ball bearing is double-row ball bearing with a spherical outer ring raceway. The inner ring, balls and cage can tilt automatically to compensate angular misalignment and shaft deflection. Mainly for radial load, can bear small bidirectional axial load. Standard series: 12,13,22,23.
Open type can compensate up to 2~3° angular misalignment. 2RS sealed version is limited to approx 1.5°. It only fixes angular tilt, cannot compensate parallel offset between shaft and housing.
Cylindrical bore: direct mounting on straight shaft. Tapered bore (1:12 taper): install with adapter sleeve, easy to adjust radial clearance, convenient for disassembly.
Avoid excessive pressing force and shaft distortion. Tapered bore version needs proper tightening of adapter sleeve to control bearing clearance. Too tight fit will lose self-aligning performance and cause overheating.
