Angular Contact Ball Bearings
Angular contact ball bearings rely on the contact angle to bear the combined radial and axial loads, and are generally used in pairs, suitable for high-speed and precision working conditions.
Single row angle contact bearing and Double row angle contact bearing
Custom dimensions, sealing, internal clearance, materials, and lubrication requirements can be evaluated.
Technical assistance for bearing selection, replacement, specification review, and custom projects.
Controlled processing, assembly, inspection, and testing throughout production.
Available in different sizes, sealing configurations, clearance, materials, and lubrication options to meet operating requirements.
Only withstand radial load plus one-way axial load. Normally used in pairs and preloadable with high limiting speed.
Integrated design equivalent to two single-row bearings mounted back-to-back. Compact structure, capable of radial + bidirectional axial loads and moment loads, easy installation. Widely used in automotive wheel hubs, water pumps and electric motors.
Split inner ring design. One single bearing can carry bidirectional axial loads with high axial capacity and save installation space. Ideal for rotary tables, robot joints and aerospace assemblies with heavy axial load & limited space.
Silicon nitride ceramic balls with steel rings. Light weight, low temperature rise, electrical insulation and excellent high-speed performance. Applied in high-speed spindles, new energy motors and high-speed centrifuges.
We control critical manufacturing processes from component preparation to final assembly and inspection to support consistent bearing quality and performance.
Raw materials are strictly inspected upon incoming to secure product quality.
Full dimensional inspection of finished products, strictly controlling geometric tolerances to ensure bearing dimensional accuracy meets design specifications.
Full visual inspection for all workpieces to eliminate scratches, rust, dents and other surface defects, ensuring intact bearing appearance.
Final full re-inspection before shipment, verifying specifications, packaging and documents to deliver qualified products to customers.

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.

Angular contact ball bearing has a contact angle between balls and raceways. It can carry combined radial and axial loads. The larger contact angle, the higher axial load capacity. Common contact angles: 15°(C), 25°(AC), 40°(B). It must be mounted in pairs for bidirectional axial positioning.
Single row: takes axial load in one direction only, usually paired mounting. Compact structure, high speed performance. Double row: bears bidirectional axial load, replaces two single row bearings, saves installation space but lower maximum speed.
15°(C): Low axial force, high precision & high speed, for machine tool spindles. 25°(AC): Balanced radial & axial load, general automation & pumps. 40°(B): Heavy axial load, low speed condition.
Preload is applying permanent axial force during assembly to eliminate internal clearance. Preload improves rigidity, reduces runout, enhances positioning accuracy for high precision equipment. Too heavy preload will cause overheating and shorten service life.
