Product Details

Easy bearing clearance: can be field adjusted to meet application needs
Mounting to suit the load and installation requirements
Shaft ready: prelubricated with standard grease for normal operation
other lubricants available for special conditions
Fully self-aligning: spherical roller bearing to accommodate operational and installation misalignment
Rugged housing: standard material – cast iron, steel or ductile iron available on request
Carburized raceways: case-carburized inner races provide a hard, fatigue-resistant surface and a tough, crack-resistant ductile core
Interchangeable seals: three types of seals to match the application requirements: Z seal, for the broad range of normal operating conditions
K seal, for dusty, dirty conditions
and M seal, for protection against liquid contamination
For extra protection under severe conditions, auxiliary caps are also available
Spherical bearing design accomodates continual misalignment.
Collar is larger, thicker, and heavier to provide increased surface area contact with shaft.
Threaded cover and microlock design allows bearing clearance adjustment, off-the-shelf units to meet special requirements.
Wedges tight during operation, even if setscrews loosen.
Carburized (case-hardened) inner ring resists fracturing, even under heavy loads
Units are completely preassembled, preadjusted, greased, sealed, and ready to mount.
Grips tight, even with undersized shafting.
