The SKF 6313-2RS1 sealed deep groove ball bearing is engineered for industrial rotating assemblies where significant shaft loads must be supported within a 140mm housing bore. Its 65mm inside diameter and 33mm width make it a substantial bearing for larger electric motors, mechanical transmissions and process equipment. The SKF Explorer design features precision-manufactured raceways and rolling elements intended to deliver reliable performance under demanding operating conditions. Its single row deep groove geometry accommodates radial loads and axial forces in either direction, within the bearing's rated limits. SKF specifies a 97.5kN basic dynamic load rating and a 60kN basic static load rating, providing essential figures for calculating bearing life and checking suitability under continuous, intermittent or peak loading.
The 2RS1 rubber contact seals retain the factory-applied grease while helping prevent airborne particles, dirt and moisture from reaching the rolling elements. This is particularly beneficial in enclosed industrial drives where regular bearing relubrication is inconvenient. SKF lists a 3,200rpm limiting speed for the contact-sealed configuration; permissible continuous operating speed also depends on temperature, loading, shaft alignment and seal friction. The bearing has normal (CN) radial internal clearance, which must be distinguished from the increased clearance of a 6313-2RS1/C3. Its approximate 2.1kg weight makes appropriate handling and controlled mounting important. Correct shaft and housing fits, bearing shoulder dimensions and thermal expansion should all be considered before installation.
Typical Applications:
Large industrial electric motor assemblies
Heavy-duty conveyor drive and pulley systems
Industrial centrifugal pumps and processing machinery
Mechanical gearboxes and power transmission equipment
Industrial fans, blowers and rotating plant machinery
