This double row angular contact ball bearing carries a filling slot design and a solid brass cage (M). Bore diameter is 85.0 mm, outside diameter 180.0 mm, and width 73.0 mm, with a net mass of 8.41 kg. Limiting speed is rated at 5000.0 1/min, with a reference speed of 3600.0 1/min, corresponding to internal clearance class C3. The filling slot construction allows a higher ball count per row, increasing radial load capacity compared to standard designs without this feature, while the double row arrangement supports combined radial and axial loads acting in both directions. The C3 clearance compensates for temperature rise during operation and interference fits on the shaft or housing. The solid brass cage guides the balls at higher speeds with reduced friction and wear compared to pressed steel cages, supporting operation up to the stated limiting speed.
