Product Overview: H 2344 OH Hydraulic Adapter Sleeve
The H 2344 OH is a high-quality hydraulic Adapter Sleeve from our OH Series, engineered for securely mounting bearings with a 220 mm tapered bore onto a 215 mm cylindrical shaft. This sleeve simplifies the mounting process by providing a reliable and precise fit without the need for complex shaft machining. The 'OH' designation signifies the inclusion of oil supply ducts and distribution grooves, which allow for the hydraulic-assisted mounting and, more importantly, dismounting of the bearing. This feature drastically reduces maintenance time and prevents damage to both the shaft and the bearing during removal.
As a key component in our range of Bearing Accessories, the H 2344 OH adapter sleeve, complete with its corresponding lock nut and lock washer, ensures a secure and concentric grip. It is an indispensable part for heavy-duty industrial applications where robust and serviceable mounting solutions are critical for operational efficiency and equipment longevity.
Key Features of the H 2344 OH Sleeve
- Hydraulic Assist (OH): Features integrated oil ducts for easy and damage-free hydraulic dismounting, saving significant time and effort during maintenance.
- Precision Taper: Machined to exact tolerances to ensure a tight, uniform interference fit between the bearing and the shaft.
- Slit Design: The sleeve is slit, allowing it to clamp down securely onto the shaft when the lock nut is tightened.
- Complete Assembly: Supplied as a set with a high-quality lock nut and a tabbed lock washer to prevent loosening under vibration.
- Simplified Mounting: Enables the use of bearings with a tapered bore on standard cylindrical shafts, eliminating the need for shaft shoulders or keyways.
- Durable Construction: Manufactured from high-strength steel to withstand high mounting forces and operational loads.
Common Applications
- Mining and Quarrying: Used in crushers, vibrating screens, and conveyor systems where heavy loads and harsh conditions are standard.
- Pulp and Paper Industry: Essential for mounting bearings on large rollers in paper machines and processing equipment.
- Industrial Fans and Blowers: Provides a secure mounting solution for large fan assemblies, ensuring balanced and reliable operation.
- Conveyor Pulleys: Facilitates the mounting of large bearings on conveyor drive and tail pulleys.
- Marine Propulsion: Used in propeller shaft arrangements and other marine machinery requiring robust bearing mounting.
- Steel Mills: Applied in rolling mills and continuous casters where equipment reliability is paramount.
- Large Gearboxes: Ensures secure and accurate positioning of gears and bearings on shafts.
Benefits of Using the H 2344 OH
- Reduced Maintenance Time: Hydraulic dismounting capability makes bearing replacement significantly faster and easier than traditional mechanical methods.
- Prevents Component Damage: Eliminates the need for hammers and pullers during dismounting, protecting the bearing and shaft from damage.
- Enhanced Operational Reliability: Provides a strong, 360-degree grip on the shaft, improving rigidity and reducing fretting corrosion.
- Cost-Effective Solution: A more economical alternative to stepped shafts or other custom shaft designs.
- Increased Bearing Service Life: A secure and accurate mounting ensures the bearing operates under optimal conditions, maximizing its lifespan.
- Versatile Application: Allows for flexible positioning of the bearing anywhere along a plain cylindrical shaft.
