Single Row Angular Contact Ball Bearings (General) 7221 BECBP

Single Row Angular Contact Ball Bearings (General) 7221 BECBP

The 7221 BECBP is a single-row angular contact ball bearing with a 105mm bore and 190mm outer diameter, crafted from sturdy chrome steel. Its 40° contact angle efficiently handles combined radial and axial loads, supporting up to 35100 lbf dynamically.

Designed for high-speed use, it spins smoothly at 4300 RPM and operates in temperatures from -30°C to 110°C. The open seal allows easy lubrication, while the nylon cage reduces friction for quieter performance.

This bearing meets P6 (ABEC-3) precision standards and is interchangeable with SKF models. Ideal for machinery like pumps or gearboxes where precise angular load support is needed.

Weighing 3.95kg, it balances durability with manageable handling. Compliant with RoHS and REACH regulations for safe industrial use.
