SKF 6314-2RS1/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 70x150x35mm

The SKF 6314-2RS1/C3 sealed deep groove ball bearing provides a robust rotating support solution for equipment built around a 70mm shaft and 150mm housing bore. Its 35mm width and substantial 63 series cross-section make it suitable for heavily loaded shafts, including those found in industrial transmission and motor assemblies. The single row deep groove raceways accommodate radial loads alongside axial forces acting in either direction, subject to the bearing's rated capacity. SKF specifies a basic dynamic load rating of 111kN and a basic static load rating of 68kN, providing important parameters for assessing fatigue life and operating loads. The SKF Explorer performance classification and pressed sheet metal cage complete a construction intended for reliable industrial operation.

The 2RS1 rubber contact seals protect both sides of the bearing, retaining the factory-applied grease and helping exclude dust, dirt and moisture. SKF lists a limiting speed of 3,000rpm for this contact-sealed configuration; actual continuous operating suitability depends on load, operating temperature, lubrication and heat generated by seal friction. Crucially, the C3 clearance provides greater initial radial internal clearance than a standard CN bearing, helping accommodate clearance reduction caused by interference mounting and thermal expansion. C3 does not mean a looser shaft or housing fit, and it should be selected according to the machine manufacturer's requirements. For replacement work, confirm the complete 6314-2RS1/C3 designation, especially the clearance suffix, rather than matching dimensions alone.

Typical Applications:

Industrial electric motors requiring C3 clearance

Heavy-duty conveyor drive and pulley assemblies

Centrifugal pumps and fluid-handling equipment

Industrial gearboxes and transmission systems

Agricultural and materials-handling machinery
