6311-2ZJEM Bearing Structural Features & Performance Benefits
Optimized Deep Groove Raceway: The geometry of the raceways is engineered to support significant radial dynamic load ratings (16,096 lbf), ensuring stable operation under varying load conditions.
Shielded Protection: The -2Z shields effectively prevent the ingress of contaminants, extending bearing service life without the torque increase associated with contact seals. This design is ideal for applications where high-speed operation (up to 5,600 rpm) is required.
Chrome Steel Construction: Manufactured from high-grade chrome steel for rings, balls, and cage, this bearing delivers high hardness, wear resistance, and long-term dimensional stability.
Standard Precision & Clearance: Manufactured to ABEC 1 | ISO P0 tolerance class with CN group radial internal clearance, providing reliable performance for a wide range of general industrial applications.
