Overview
The SKF GEZ 300 ES-2RS is a precision radial spherical plain bearing engineered for demanding industrial automation and motion control systems. This bearing is a steel/steel spherical plain bearing with rubber seals on both sides and standard radial internal clearance. It is suitable for pivoting, high load bearing applications where angular misalignment is required, such as in hydraulic cylinder rod ends. Built for reliability in mechanical power transmission and heavy-duty mechanical assembly applications, this bearing delivers consistent performance in equipment where shaft deflection and angular misalignment must be accommodated.
Key Features
- Double Nitrile seals keep out contaminants, and wide inner ring cross section provides high misalignment adjustment.
- Outer race has a single fracture for ease of inner ring installation; inner and outer rings have grooves and oil holes for ease of lubrication.
- Inner and outer rings are manufactured from through-hardened carbon chromium steel and heat treated to increase hardness for optimum wear resistance.
- Self-aligning capability allows adjustment to angle changes between shaft and housing, making it easy to handle shaft deflections.
- New in Box condition – never installed, ready for immediate deployment.
