REXN ER12 Eccentric Locking Insert Bearing | 3/4" Bore | Heavy Duty Wide Inner Ring
The REXN ER12 series is a premium wide inner ring insert bearing designed for demanding operational environments, including high-dust and moisture exposure typical in agricultural, textile, and materials handling industries. Engineered with high-strength 52100 chrome steel for superior fatigue life, this bearing features an extended inner ring on one side, providing enhanced shaft support and stability, significantly reducing vibration and misalignment potential. The inclusion of a robust eccentric locking collar ensures positive, high-retention shaft fixation, simplifying installation while guaranteeing optimal torque transfer and minimizing shaft slippage under heavy loads. All units are factory pre-lubricated with high-performance EP2 grease and feature hardened raceways for extended service intervals.
Durability is paramount with the REXN ER12, which utilizes R3 Triple-Lip Contact Sealing technology. This highly effective sealing system acts as a multi-stage barrier, protecting the internal raceways from abrasive contaminants and effectively retaining vital lubrication, drastically prolonging the operational life of the unit in harsh conditions. Its deep groove ball bearing configuration ensures high radial and moderate axial load capacities. The robust construction and precision manufacturing make the ER12 an ideal replacement for applications requiring reliable, easy-to-install units that minimize costly downtime and maintenance expenditure.
