Deep groove ball bearing 6222-M-C4 carries radial loads on a single row of balls guided by a solid brass cage (M), running in a bore of 110.0 mm and outside diameter of 200.0 mm, with a width of 38.0 mm and a net mass of 5.27 kg. The limiting speed reaches 5800.0 1/min, with a reference speed of 4500.0 1/min, giving the bearing stable performance at higher rotational speeds thanks to the solid brass cage construction. The radial internal clearance C4 (Group 4) is larger than standard, which allows the bearing to compensate for thermal expansion of the shaft during operation and maintain proper operating clearance under elevated running temperatures typically associated with the higher speed range this bearing supports. The solid brass cage provides strength and stability at these speeds, keeping the balls evenly spaced and reducing friction-related heat generation within the bearing.
