SKF Cylindrical Roller Bearing 40 mm ID 90 mm OD 23 mm Race Width Steel Rollers Sheet Metal Cage 21308 E

SKF 21308 E Cylindrical Roller Bearing features a 40 mm inside diameter, 90 mm outside diameter, and a 23 mm race width. It utilizes steel rollers and a sheet metal cage, making it suitable for handling radial loads with high durability and reduced friction. The internal clearance class CN allows for moderate radial displacement to accommodate thermal expansion and misalignment without excessive preload. With a static load rating of 108 kN and dynamic load rating of 107 kN, this bearing resists deformation under heavy loads and maintains sustained performance under operational stress. Its limiting speed of 9500 rpm allows for high-speed applications.

This bearing is engineered for industrial gearboxes, rotating shafts, and assemblies requiring single-row load support with cylindrical bore mounts. Its steel rolling elements and metal cage provide wear resistance and robustness needed for demanding industrial, manufacturing, and mechanical use cases. The bearing is designed to fit onto plain shafts, ensuring secure mounting and reliable function.

Applications include heavy machinery, material handling equipment, and rotary components in industrial plants where durability and precision are essential. The bearing’s construction supports long-term operational reliability under moderate to high-speed rotation.

Steel rollers ensure wear resistance and reliable rolling contact. Sheet metal cage minimizes friction and maintains precise roller spacing. Single-row design suited to moderate-speed radial load applications. Supports stationary heavy loads without permanent deformation.

Internal clearance accommodates thermal and alignment fluctuations effectively.

For those in need of high-quality rotary bearings for mechanical machinery and spares, the SKF 21308 E guarantees trusted performance and compatibility with existing industrial equipment. Explore more products in the Roller Bearings category on EnvMart for all your mechanical bearing needs.
