SKF Spherical Roller Bearing Tappered Bore 90 mm ID 190 mm OD 43 mm Width 4800 rpm Limiting Speed 21318 E

SKF 21318 E spherical roller bearing featuring a tappered 90 mm inside diameter and 190 mm outside diameter is designed for industrial and mechanical applications requiring robust load capacity and durability.

The bearing includes two rows of precision steel rollers and a common spherical outer ring raceway with inner rings inclined at an angle to the bearing axis. This design allows accommodation of radial and axial loads in both directions.

With a race width of 43 mm and internal clearance classified as C3, this bearing ensures smooth operation under varying temperature and load conditions. It supports a limiting speed of 4800 rpm, making it suitable for high-speed rotating equipment.

Constructed from bearing-grade steel, the 21318 E series bearing delivers excellent wear resistance and operational reliability. Static and dynamic load ratings of 450 kN and 393 kN respectively make it suitable for heavy industrial machinery and conveyors.

The tappered bore type enables a secure and precise fit on shafts, reducing vibration and wear. Originating from SKF’s manufacturing facilities in the United Kingdom, the bearing reflects stringent quality control and engineering excellence.

The bearing has two rows of steel rollers for optimal load distribution. Its design accommodates both radial and axial loads efficiently. Internal clearance C3 enhances thermal expansion tolerance. Limiting speed of 4800 rpm supports high operational velocity.

High static and dynamic load ratings suitable for demanding applications. Tappered bore for secure shaft mounting. Manufactured in the United Kingdom ensuring high standards.

This SKF Spherical Roller Bearing 21318 E is widely used in industrial tools, mechanical machinery, manufacturing equipment, and conveyor systems requiring reliable bearing performance under heavy loads and high speeds.
