从China供应商批发进口22317mb/W33 Spherical Roller Bearing — FOB条款

The 22317MB/W33 spherical roller bearing is a heavy-duty bearing component with an 85mm bore diameter, 180mm outer diameter, and 60mm width, designed for applications requiring high radial load capacity and self-aligning capability. This bearing features a double-row spherical roller design with a pressed steel cage (MB designation) and comes with a W33 groove for external lubrication. The product is manufactured from GCR15 chrome steel, also known as high carbon chromium bearing steel, which provides superior hardness, wear resistance, and fatigue life in demanding industrial environments.

GCR15 chrome steel is the standard material for spherical roller bearings in industrial applications, offering typical hardness of 60-65 HRC after heat treatment. The bearing features self-aligning capability of approximately 1.5 to 2.5 degrees, accommodating shaft misalignment without premature failure. Clearance options include C0, C2, C3, C4, and C5 designations, with C3 being standard for most industrial applications. Precision ratings range from P0 (standard) to P5 (high precision), with vibration classes ZV1, ZV2, and ZV3 available for low-noise applications.

This bearing is extensively used in mining equipment, construction machinery, cement plants, industrial gearboxes, and power transmission systems requiring reliable performance under heavy loads.
