Machined Brass Cage 95BAR10S Super Precision Angular Contact Thrust Ball Bearings
The 95BAR10S Ultra-precision angular contact thrust ball bearings are designed for high-load, high-speed applications with stringent requirements for axial runout, and are widely used in precision machine tool spindles, ball screws, industrial robot joints, aero-engine accessory transmission systems, and high-precision centrifuges.
The 95BAR10S bearing is a Super Precision Angular Contact Thrust Ball Bearings, High-Speed with an inner diameter of 95 mm , an outer diameter of 145 mm, a width of 45 mm. S = bearing steel (SUJ2) rings, S = bearing steel (SUJ2) rolling mlement. Its dynamic radial rated load is approximately 43000 N, its static radial rated load is approximately 96500 N. together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
95BAR10S bearings ( 95 mm x 145 mm x 45 mm) have the advantages of perfect balance of rotational accuracy, speed and rigidity, and are therefore widely used in the Machine tools, ball screw, aerospace, medical equipment.

The core design of ultra-precision angular contact thrust ball bearings lies in their large contact angle (typically 60°) and high-precision matching steel balls, which can simultaneously withstand heavy axial loads and radial loads. With optimized raceway geometry and cage, they achieve extremely low friction and high rigidity, ensuring that they maintain nanometer-level rotational accuracy and excellent axial positioning capability during high-speed operation.
