SKF 6018-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 90x140x24mm

The SKF 6018-2RS1 sealed deep groove ball bearing is engineered for rotating equipment that requires a 90mm shaft bearing without the additional housing space of a heavier 62 or 63 series arrangement. Its single row ball and raceway design supports radial loads alongside moderate axial loads acting in either direction. SKF specifies a basic dynamic load rating of 60.5kN and a static load rating of 50kN, providing useful reference values when assessing bearing life and stationary loading. The bearing's pressed steel cage and SKF Explorer design make it suitable for a range of continuous-duty industrial applications, provided operating conditions remain within the manufacturer's limits.

The 2RS1 double contact seal arrangement retains the factory lubricant and helps protect the internal raceways from dust, dirt and moisture. This is particularly valuable in equipment where routine relubrication is difficult. Contact seals introduce more friction than open bearings, however, so operating speed and heat generation should be considered during selection. The specified limiting speed is 2,800rpm, and normal radial internal clearance should be checked against shaft interference fits, housing tolerances and operating temperature before installation.

Typical Applications:

Large industrial electric motors

Centrifugal pump shaft assemblies

Industrial ventilation fans and blowers

Conveyor drive and pulley systems

Mechanical transmission equipment
