SKF Cylindrical Bore Steel Roller Bearing 35 mm ID 80 mm OD 21 mm Race Width SRB Series 12000 rpm Limiting Speed 21307 CC

SKF 21307 CC Cylindrical Bore Steel Roller Bearing is a precision-engineered component featuring a 35 mm inside diameter, 80 mm outside diameter, and 21 mm race width. This SRB series bearing is made from high-quality steel rollers and a sheet-metal cage, designed to withstand heavy radial and moderate axial loads in diverse industrial applications.

The bearing's two-row spherical roller design accommodates axial misalignment while maintaining even load distribution across the rollers, enhancing operational reliability. It features a cylindrical bore which facilitates easy shaft mounting and ensures compatibility with various shaft sizes.

The static load rating of 72 kN and dynamic load rating of 79.2 kN provide exceptional resistance against static and shock loads. With a limiting speed of 12000 rpm, it supports high-speed operations. The internal clearance CN grants controlled running conditions and options for preload adjustment.

Common applications include use in high-load gearbox shafts for automation systems, conveyor drive rolls in material handling equipment, electric motor shafts subject to axial misalignment, rotary joints in production-line machinery, and in bearing configurations for heavy-duty pumps and compressors.

The bearing is manufactured in Malaysia, weighing approximately 0.54 kg, which is vital for dynamic balancing and rotor inertia considerations. Two-row spherical roller design for high radial and moderate axial loads. Steel rollers and sheet-metal cage ensure durability and reduced friction.

Static load rating of 72 kN and dynamic load rating of 79.2 kN for heavy-duty performance. Limiting speed of 12000 rpm suitable for high-speed applications. Cylindrical bore enables straightforward installation on shafts.
