Barrel roller bearing accommodates shaft misalignment through its symmetrical barrel-shaped rolling elements running on a curved outer raceway. The 20210-K-TVP-C3 has a 50.0 mm bore, 90.0 mm outside diameter, 20.0 mm width, and a net mass of 0.472 kg. It is fitted with a polyamide cage (TVP) and a tapered bore (K designation) for mounting on an adapter or withdrawal sleeve. Limiting speed is 7700 1/min, and radial internal clearance is increased per C3 (Group 3). The C3 clearance compensates for thermal expansion and interference fit from the tapered bore mounting, keeping operating clearance within the intended range after fitting. The barrel roller design allows for angular misalignment between shaft and housing, making it suitable where shaft deflection or housing misalignment must be tolerated without additional stress on the rolling elements. As supplied unsealed, lubrication (grease or oil) and sealing must be provided by the housing arrangement.
