Product Overview 22220CA/W33 is a heavy‑duty double‑row spherical roller bearing fitted with machined brass CA cage and standard W33 lubrication feature. Capable of sustaining substantial radial loads together with moderate two‑way axial loads, this bearing is widely deployed in various demanding industrial operating environments.
Core Structural & Performance Advantages
Superior Self‑aligning Capability Accommodates shaft deflection and installation misalignment up to 1.5 degrees. Effectively prevents bearing seizure and premature failure triggered by assembly deviation or shaft deformation.
Outstanding Heavy‑load Performance Symmetric double‑row spherical rollers realize even pressure distribution across contact surfaces. The bearing maintains reliable operation under sustained heavy‑duty working cycles.
W33 Lubrication Structure for Extended Service Life Designed with circumferential outer‑ring oil groove together with three oil injection holes. It facilitates even distribution of grease or lubricating oil, lowering friction loss and component wear.
Robust Machined Brass CA Cage Solid brass machined cage delivers exceptional structural rigidity. It resists deformation even under combined high‑speed rotation and heavy impact loading.
GCr15 Quenched Bearing Steel for Wear Resistance Bearing rings and rollers are manufactured from quenched GCr15 chrome steel. High material hardness brings good anti‑corrosion property and strong fatigue resistance.
