Overview
The 6205-2RS is a single-row deep groove ball bearing with contact seals on both sides. It carries radial load, takes a modest axial load in either direction, and is supplied greased so the seals do not have to be removed for the first fill.
Design and construction
Rings and balls are through-hardened 100Cr6. The raceways are ground and honed, the cage is stamped steel, and the nitrile seals keep the factory grease in and ordinary workshop dust out. Internal clearance is CN. C3 can be quoted when the shaft fit or the temperature difference would close a normal clearance.
Typical applications
- Electric motors and small generators
- Pump and fan shafts
- Gearbox layshafts
- Conveyor rollers
