This single row deep groove ball bearing carries the bore type Z with a bore diameter of 130.0 mm, outside diameter of 280.0 mm, and width of 58.0 mm, giving a net mass of 17.88 kg. It is fitted with a solid brass cage (M) and features radial internal clearance C3, which provides a larger internal clearance than the standard group. Limiting speed is rated at 4150 1/min, with a reference speed of 3500 1/min. The solid brass cage supports stable ball guidance at the stated speed range and adds mechanical strength under load. The C3 clearance compensates for temperature rise and interference fit effects during operation, making this bearing suitable where shaft and housing fits require additional internal clearance to maintain proper operating conditions. As an open bearing without integrated sealing, it requires external sealing and a separate lubrication arrangement suited to the application's operating speed and temperature.
