This deep groove ball bearing supports radial loads and moderate axial loads in a single row of balls, with a solid brass cage (MA) guiding the rolling elements for stable operation at higher speeds. Bore diameter is 40.0 mm, outside diameter 68.0 mm, and width 15.0 mm, with a net mass of 0.237 kg. The limiting speed is 18900 1/min and the reference speed is 10600 1/min. The radial internal clearance is C3 (Group 3), providing greater internal play than standard clearance to compensate for thermal expansion during operation at elevated speeds or temperatures. The solid brass cage offers strength and dimensional stability under higher rotational speeds and centrifugal forces compared to pressed steel cages. This bearing is supplied without seals or shields, requiring external lubrication and protection from contamination, and is suited for applications where increased internal clearance and cage rigidity are required for reliable radial load support.
