Machined Brass Cage BRSA340SVDBCP95 High-Accuracy Low-Profile Angular Contact Ball Bearings
The BRSA340SVDBCP95 Ultra-precision angular contact ball bearings are widely used in machine tool spindles (machining centers, lathes), high-speed electric spindles, ball screw support mechanisms, humanoid robot rotary joints, eVTOL gas turbine generators, and low-altitude aircraft drive systems.
The BRSA340SVDBCP95 bearing is a High-Accuracy Low-Profile Angular Contact Ball Bearings with an inner diameter of 340 mm , an outer diameter of 420 mm, a width of 50 mm. It typically uses P5 (ABEC-5) grade precision tolerances and S = SUJ2 or SUJ3 rings, SUJ2 rolling mlement. Its dynamic axial rated load is approximately 97292 N, its static axial rated load is approximately 559531 N. V = Non-contact rubber seal on one side type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
BRSA340SVDBCP95 bearings ( 340 mm x 420 mm x 50 mm) have the advantages of High speed, ultra-precision, high rigidity, low operating friction, and long service life, and are therefore widely used in the Machine tool spindles, high-speed motors, ball screws, industrial robots and precision rotating equipment.

The BRSA340SVDBCP95 Ultra-precision angular contact ball bearings are primarily composed of high-precision bearing steel inner and outer rings, steel balls (ceramic balls or EQTF? ultra-long life steel balls optional), and a cage. Contact angles are available in various specifications including 15°, 18°, 25°, 30°, and 40°. Cages are available in polyamide resin (TYN), phenolic resin (TR), and copper alloy materials.
Ultra-precision angular contact ball bearings utilize Robust series technology, achieving low heat generation and ultra-high speeds through optimized internal dimensional design. Using the independently developed SHX heat-resistant steel material, rolling fatigue life is extended to four times that of SUJ2 material, and high-speed performance is improved by 20%. Employing oil-air lubrication SpinShot II technology, speeds up to 40,000 rpm in the NT#40 class, with noise reduction of 3-5 dB.
