Key Features of the H 31/630
- Facilitates Easy Mounting: Simplifies the process of mounting bearings with a tapered bore onto cylindrical shafts.
- Secure and Reliable Fit: When tightened with the supplied lock nut, the sleeve provides a strong interference fit, preventing the bearing from spinning on the shaft.
- Cost-Effective Shaft Design: Allows for the use of standard commercial-grade shafts with wider tolerances, reducing manufacturing costs.
- Simplified Dismounting: Makes bearing removal straightforward, minimizing machine downtime during maintenance or replacement.
- Complete Assembly: Typically supplied as a complete set with a precision-engineered lock nut and a secure lock washer.
- Durable Construction: Made from high-strength steel to withstand high mounting forces and operational loads.
Common Applications
- Mining and Quarrying: Used in large crushers, grinding mills, and heavy-duty conveyor systems where large shafts are common.
- Pulp and Paper Industry: Essential for mounting bearings on the large rollers used in paper machines and processing equipment.
- Steel and Metal Rolling Mills: Provides reliable bearing mounting on the rolls and drives of rolling mill stands.
- Large Industrial Gearboxes: Ensures secure positioning of bearings on input and output shafts in heavy-power transmission systems.
- Power Generation: Applied in turbines, generators, and other large rotating equipment in power plants.
- Marine Propulsion Systems: Used for mounting bearings on propeller shafts and in large marine gear units.
- Heavy Industrial Fans and Blowers: Secures bearings in large-scale ventilation and air-handling units for industrial facilities.
Benefits of Using the H 31/630 Adapter Sleeve
- Enhanced Operational Reliability: Provides a secure, concentric grip that ensures the bearing is properly located, maximizing its performance and lifespan.
- Reduced Maintenance Time: The straightforward mounting and dismounting procedure significantly cuts down on labor time and complexity.
- Increased Versatility: Bearings can be located at any position along a plain shaft, offering greater design flexibility.
- Lower Overall Costs: Eliminates the need for special shaft shoulders, keyways, or other expensive machining operations.
- Improved Equipment Uptime: The reliability of the mounting system reduces the likelihood of premature bearing failure and unscheduled stops.
- Accommodates Shaft Tolerances: Can be used on shafts with wider diameter tolerances than those required for direct press-fits.
