This single row deep groove ball bearing carries a bore of 20.0 mm, outside diameter of 47.0 mm, and width of 14.0 mm, with a net mass of 0.094 kg. It belongs to Generation C design and features a TVH cage made of glass-fibre reinforced plastic. Radial internal clearance is set to C3 (Group 3), providing a larger internal clearance than standard. The limiting speed reaches 24300 1/min, with a reference speed of 18100 1/min. The C3 clearance compensates for tighter fits and thermal expansion during operation, keeping the bearing free of excessive preload under such conditions. The TVH plastic cage allows smooth ball guidance at the stated speed range while reducing friction and mass compared to solid cages. No sealing or shielding is specified, so lubrication and contamination protection must be provided externally, matching the open bore type Z design.
