SKF Spherical Roller Bearing Tapered Bore 80 mm ID 170 mm OD 375 kN Static Load 331 kN Dynamic Load Series SRB 21316 EK/C3

SKF 21316 EK/C3 spherical roller bearing with a tapered bore of 1:12 ratio is engineered for robust industrial rotary applications requiring high load capacity and durability. This bearing features two rows of symmetrical steel rollers running on a common sphered outer ring raceway with two inner ring raceways inclined relative to the bearing axis. The centre of the spherical outer ring raceway aligns with the bearing axis to accommodate misalignment and heavy radial and axial loads.

The bearing has an inside diameter of 80 mm, outside diameter of 170 mm, and a race width of 39 mm, making it suitable for medium to large machines. It uses high-quality steel for both the bearing and roller material to ensure long-term reliability under demanding conditions.

Performance ratings include a static load rating of 375 kN and a dynamic load rating of 331 kN. The limiting speed is 5300 rpm, enabling it to operate efficiently in high-speed industrial equipment.

This spherical roller bearing is part of SKF's SRB series, representing advanced engineering for heavy-duty mechanical power transmission, manufacturing equipment, conveyors, and rotating machinery. It is widely used in industries such as construction, mining, steel production, and power generation.

This bearing features a tapered 1:12 bore for easy fitting and secure mounting. The steel construction of rollers and bearing ensures durability under heavy loads and harsh operating conditions. Its design compensates for shaft misalignments, reducing wear and increasing machine life.

The SRB series quality provides superior radial and axial load support. Originating from the United Kingdom, it meets stringent quality and manufacturing standards. This rolling element bearing is an essential component for industrial machinery requiring reliable load support and rotational performance.
