This deep groove ball bearing carries radial and moderate axial loads through a single row of balls guided by a solid brass cage (MA). Bore diameter is 300.0 mm, outside diameter 420.0 mm, width 56.0 mm, net mass 24.8 kg. Limiting speed reaches 2600.0 1/min, reference speed 1890.0 1/min, and the design corresponds to bore type Z. Radial internal clearance C3 (Group 3) provides increased clearance, compensating for thermal expansion under elevated operating temperatures and interference fits. The solid brass cage withstands higher speeds and temperatures compared to pressed steel cages and offers stable ball guidance under demanding conditions. The 61960-MA-C3 bearing is supplied without integrated seals, requiring external lubrication and sealing arrangements suited to the operating environment.
