ZA3215

features

• 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
