This single row deep groove ball bearing carries a bore diameter of 140.0 mm, outside diameter of 250.0 mm, and width of 42.0 mm, with a net mass of 9.061 kg. It is fitted with a solid brass cage (M) and features C3 radial internal clearance, providing a larger internal clearance than standard to compensate for operating temperature rise and interference fit effects. The limiting speed is rated at 4650.0 1/min, with a reference speed of 3600.0 1/min. The solid brass cage construction allows stable ball guidance and durability under elevated operating temperatures, making this bearing suitable for higher speed ranges within its rated limits. The C3 clearance class accommodates thermal expansion and tighter fits during mounting, supporting reliable radial load handling at the stated bore diameter. As an open bearing design, relubrication and external sealing arrangements must be provided according to the operating environment and mounting conditions.
