Product Overview: H 3048 OH Hydraulic Adapter Sleeve
The H 3048 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 220mm diameter. As a crucial component in our Adapter Sleeves range, this sleeve is part of the specialized OH Series and OH 3000 Series, engineered to facilitate easy and secure hydraulic mounting and dismounting. The 'OH' designation signifies the inclusion of oil supply ducts and distribution grooves, which allow hydraulic fluid to be injected between the sleeve and the bearing bore. This process significantly reduces the force required for installation and removal, preventing damage to both the bearing and the shaft.
This assembly includes the hydraulic adapter sleeve, a corresponding lock nut, and a lock washer, providing a complete solution for robust and precise bearing positioning. It is an essential accessory for heavy-duty applications where reliability and ease of maintenance are paramount.
Key Features of the H 3048 OH
- Hydraulic Mounting Design: Features integrated oil ducts and grooves for simplified, low-force hydraulic installation.
- Complete Assembly: Supplied as a set with a precision-matched lock nut and lock washer for secure fastening.
- Facilitates Easy Dismounting: The hydraulic system also enables effortless removal of the bearing, reducing downtime and labor costs.
- Precision Machined Taper: Ensures a true and accurate seating for the bearing, maximizing its performance and operational life.
- Slit Sleeve Construction: Provides strong, uniform clamping force around the shaft for a reliable and concentric fit.
- High-Strength Material: Manufactured from durable steel to withstand high mounting forces and operational loads.
Common Applications
- Mining and Quarrying: Used in large crushers, grinding mills, and conveyor drive pulleys where heavy bearings are common.
- Pulp and Paper Industry: Ideal for mounting bearings on large rollers in paper machines, ensuring precise alignment.
- Heavy Industrial Fans and Blowers: Secures large bearings in ventilation systems that operate under demanding conditions.
- Marine Propulsion Systems: Applied in propeller shafts and gearboxes for reliable and maintainable bearing arrangements.
- Construction Equipment: Utilized in heavy machinery like excavators and cranes for mounting large slewing rings and drive components.
- Steel Manufacturing: Essential for roll-neck bearings in rolling mills, where frequent and quick bearing changes are required.
Benefits of Using the H 3048 OH
- Damage-Free Installation: Hydraulic mounting eliminates the need for hammering or excessive force, protecting sensitive bearing components.
- Reduced Maintenance Time: Simplifies and speeds up both the mounting and dismounting processes, increasing machine availability.
- Enhanced Precision: Allows for exact axial positioning of the bearing on the shaft, leading to improved operational accuracy.
- Improved Operational Reliability: Creates a solid, interference fit that prevents fretting corrosion between the shaft and sleeve.
- Increased Safety: Reduces the physical effort and risks associated with traditional mechanical mounting of large bearings.
- Cost-Effective Solution: While an initial investment, the long-term savings in reduced labor, component damage, and downtime are significant.
