Product Overview: The H 3172 OH Hydraulic Adapter Sleeve
The H 3172 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a tapered bore onto 360mm cylindrical shafts. As a crucial component in our Sleeves collection, this part belongs to the robust OH Series, which is specifically engineered for hydraulic-assisted mounting and dismounting. The integrated oil supply ducts allow for the injection of oil under high pressure between the sleeve and the bearing, significantly reducing the force required for installation and removal. This feature is particularly vital for large and heavy bearings, preventing damage to both the bearing and the shaft during maintenance.
This adapter sleeve provides a secure, concentric fit, ensuring optimal performance and reliability in demanding industrial environments. The H 3172 OH assembly includes the sleeve, a high-precision lock nut, and a lock washer, offering a complete solution for securely positioning bearings on plain shafts without the need for shoulders or other locating features.
Key Features of the H 3172 OH
- Hydraulic Mounting/Dismounting: Features integrated oil supply ducts and distribution grooves for easy, low-force, and damage-free hydraulic installation and removal.
- Secure Bearing Location: Enables bearings with a tapered bore to be securely fastened onto plain cylindrical shafts, providing a reliable friction fit.
- Complete Assembly: Supplied as a complete set with a precision-grade lock nut and lock washer for secure and accurate positioning.
- Simplified Shaft Design: Eliminates the need for expensive shaft machining (e.g., shoulders or keyways), allowing for more straightforward and cost-effective system design.
- High-Quality Construction: Manufactured from high-strength steel to withstand high mounting forces and operational loads, ensuring long-term durability.
- Versatile Positioning: Allows bearings to be located at any position along a plain shaft, offering flexibility in machine design.
Common Applications
- Heavy Industrial Gearboxes: Ensures secure mounting of large gears and bearings in high-torque applications.
- Mining and Construction: Used in heavy-duty equipment like crushers, conveyors, and excavators where robust bearing arrangements are essential.
- Pulp and Paper Machinery: Ideal for mounting bearings in large rollers, drying cylinders, and winders.
- Marine and Offshore: Applied in propeller shafts, thrusters, and deck machinery where reliability and ease of maintenance are critical.
- Steel and Metal Rolling Mills: Facilitates the mounting of work rolls and back-up roll bearings that are subject to extreme loads and frequent changes.
- Large Fans and Blowers: Provides a secure and reliable method for mounting bearings in industrial ventilation systems.
Benefits of Using the H 3172 OH
- Reduced Maintenance Time: Hydraulic assistance dramatically speeds up the mounting and dismounting process, minimizing equipment downtime.
- Prevents Component Damage: Eliminates the risk of damaging the bearing bore or shaft surface that can occur with traditional mechanical methods.
- Enhanced Operational Safety: Controlled hydraulic pressure provides a safer alternative to using hammers and excessive physical force for large bearing installation.
- Improved Reliability: Achieves a precise and uniformly strong interference fit, enhancing the overall stability and performance of the bearing assembly.
- Cost-Effective Solution: Reduces overall costs by simplifying shaft design and maintenance procedures, and by extending the service life of bearings and shafts.
- Accurate and Repeatable Mounting: The hydraulic method allows for highly accurate and consistent positioning of bearings on the shaft.
