Rollway Bearing 22222W33K Spherical Bearing

Rollway 22222W33K is a heavy‑duty double‑row spherical roller bearing from the Rollway 22200 series, engineered to support high radial loads with shaft misalignment. It features a 110 mm bore, 200 mm outer diameter, and 53 mm width, and uses a machined brass cage (MB). The outer ring includes W33 lubrication grooves with three lubrication holes, a design that accommodates grease or oil lubrication and helps maintain smooth operation under demanding conditions. Constructed from high‑carbon chromium steel for the raceways and rollers, this bearing balances strength and durability in demanding applications. Typical service speeds are listed as up to around 1,700 rpm with grease lubrication and up to about 2,200 rpm with oil lubrication, depending on mounting and lubrication strategy. Applications for this bearing family include heavy machinery where robust radial support and some misalignment tolerance are required, such as gearboxes, conveyors, and other industrial equipment that handles substantial loads.
