Deep Groove Ball Bearings SKF 6310 -2RS1/C3

The SKF 6310 -2RS1/C3 deep groove ball bearing, measuring 50x110x27 mm, offers protection against dirt and allows for thermal expansion.

The SKF 6310 -2RS1/C3 deep groove ball bearing is a single-row radial ball bearing made from 100Cr6 rolling bearing steel for shafts with a diameter of 50 mm. With an outer diameter of 110 mm and a width of 27 mm, this component primarily accommodates radial loads as well as moderate axial loads. Thanks to the factory-fitted contact seals and the increased C3 bearing clearance, the bearing unit operates reliably in rotating shaft assemblies, even under demanding environmental conditions and operational heating.

What is the 6310-2RS1/C3 deep-groove ball bearing suitable for in operation?

This design is particularly suitable for demanding bearing locations where dusty environmental conditions prevail. The seals, which rub against the bearing on both sides and are made from a material with a steel insert, keep out dirt particles and moisture, whilst the lubricant remains inside the bearing. Thanks to its robust design featuring a guided sheet steel cage, the rolling bearing can withstand continuous rotational movement. The permissible temperature range of –20 to +120 degrees covers standard requirements for continuous industrial operation.

What are the advantages of the C3 bearing clearance in combination with the 2RS1 seal?

The C3 designation indicates a slightly increased radial bearing clearance compared with the standard version. This additional internal clearance helps to prevent stress build-up if the inner ring and shaft expand more than the housing due to friction or external heat. This ensures that sufficient operating clearance remains even with tight-fit selections. In combination with the contact-type 2RS1 seal, you obtain a ready-to-fit, sealed component in tolerance class P0/PN, which eliminates the need for relubrication and reduces installation effort.
