SKF 6011-2RS1/GJN Rubber Sealed High Temperature Deep Groove Ball Bearing 55x90x18mm

The SKF 6011-2RS1/GJN sealed deep groove ball bearing provides support for 55mm rotating shafts where bearing dimensions, load capacity and lubricant specification must be considered together. Its single row ball and raceway design carries predominantly radial loads while accommodating moderate axial forces in both directions. The bearing has a basic dynamic load rating of 29.6kN and a basic static load rating of 21.2kN, with a catalogue limiting speed of 4,500rpm. Its relatively narrow 60 series cross-section is useful where a wider bearing arrangement would occupy unnecessary space, provided the calculated operating loads remain within suitable limits.

The distinguishing feature is the GJN grease specification, which identifies SKF's polyurea-thickened, mineral-oil-based lubricant. This matters when replacing bearings in machinery where grease type is specified by the equipment manufacturer. The 2RS1 rubber contact seals protect both sides, helping retain lubricant and reduce exposure to dust and moisture without routine relubrication. Normal radial internal clearance is supplied rather than C3, so shaft interference fits and operating temperatures should be checked before installation. Contact seals also introduce friction compared with open bearings, making heat generation and continuous running speed important selection considerations.

Typical Applications:

Industrial electric motors with specified grease requirements

Ventilation fans and blower assemblies

Industrial circulation pumps

Conveyor drive and pulley shaft systems

Enclosed mechanical transmission equipment
