Product Overview: H 3148 OH Hydraulic Adapter Sleeve
The H 3148 OH is a high-performance hydraulic adapter sleeve designed for securely mounting bearings with a tapered bore onto 220mm cylindrical shafts. As a crucial component in our Adapter Sleeves range, this assembly is part of the robust OH 3100 Series and comes complete with a lock nut and lock washer. The integrated oil supply ducts facilitate hydraulic mounting and dismounting, a method that significantly reduces the force required, prevents damage to the bearing and shaft, and ensures a precise, reliable fit.
Engineered for heavy-duty applications, the H 3148 OH adapter sleeve simplifies the bearing installation process on plain or stepped shafts. Its precision-engineered taper ensures full contact with the bearing's inner ring, providing excellent concentricity and operational stability. This makes it an essential solution for large machinery where reliability and ease of maintenance are paramount.
Key Features of the H 3148 OH
- Hydraulic Mounting/Dismounting: Features oil ducts and distribution grooves for the hydraulic method, simplifying installation and removal.
- Complete Assembly: Supplied as a complete set including the adapter sleeve, a high-strength lock nut, and a secure lock washer.
- Precision Taper: The 1:12 taper on the sleeve's outer surface provides a secure interference fit with the bearing's tapered bore.
- Slotted Design: The sleeve is longitudinally slit, allowing it to compress firmly onto the shaft when the lock nut is tightened.
- High-Quality Material: Manufactured from durable, high-grade steel to withstand high mounting forces and operational loads.
- Versatile Shaft Compatibility: Enables the use of standard, commercial-grade cylindrical shafts, reducing the need for costly custom machining.
Common Applications
- Mining and Quarrying Equipment: Used in crushers, mills, and large conveyor systems where bearings are subjected to heavy loads and harsh conditions.
- Pulp and Paper Industry: Ideal for mounting bearings in paper machines, rollers, and processing equipment.
- Large Industrial Fans and Blowers: Ensures secure and concentric mounting for large fan shafts, minimizing vibration and noise.
- Construction Machinery: Employed in heavy equipment like excavators and cranes for mounting large bearings in gearboxes and rotating assemblies.
- Steel and Metal Processing: Provides reliable bearing mounting solutions for rolling mills and continuous casting machines.
- Power Generation: Used in turbines, generators, and other large rotating equipment that require robust bearing arrangements.
Benefits of Using the H 3148 OH
- Simplified Maintenance: Hydraulic dismounting makes removing large bearings quick and easy, drastically reducing machine downtime.
- Damage-Free Installation: The hydraulic method eliminates the need for striking or excessive force, protecting the precision-ground surfaces of the bearing and shaft.
- Enhanced Operational Reliability: Achieves a strong, uniform interference fit, which prevents fretting corrosion and ensures the bearing operates smoothly.
- Cost-Effective Solution: Allows for the use of less expensive, straight cylindrical shafts instead of stepped shafts with integrated bearing seats.
- Accurate Bearing Positioning: Enables precise axial positioning of the bearing on the shaft, which is critical for many industrial applications.
- Improved Safety: Hydraulic mounting is a controlled process that is safer for technicians compared to traditional mechanical methods for large bearings.
