Product Overview: The H 3092 OH Adapter Sleeve
The H 3092 OH is a precision-engineered adapter sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 450mm diameter. As a key component in our OH Series, this sleeve features integrated oil supply ducts and distribution grooves, facilitating the hydraulic method for easy and secure mounting and dismounting of large bearings. This advanced design significantly reduces the force required for installation, preventing damage to both the bearing and the shaft.
Part of our extensive range of Adapter Sleeves, the H 3092 OH provides a complete mounting solution when used with a corresponding lock nut and lock washer. It allows bearings to be positioned at any point on a smooth shaft, offering flexibility in machine design and assembly. Its robust construction ensures a reliable and rigid connection, essential for heavy-duty industrial applications.
Key Features of the H 3092 OH
- Hydraulic Mounting/Dismounting: Equipped with oil ducts and grooves for use with the oil injection method, simplifying the handling of large, interference-fit bearings.
- Secure Bearing Location: Enables precise axial positioning of bearings on cylindrical shafts, ensuring optimal performance.
- Versatile Application: Allows for the use of standard, non-stepped shafts, reducing manufacturing complexity and cost.
- Complete Assembly: Designed to be used with a lock nut and lock washer to firmly secure the bearing in place against the sleeve.
- High-Grade Steel Construction: Manufactured from durable, high-strength steel to withstand heavy loads and demanding operational conditions.
- Split Sleeve Design: The sleeve is slotted, allowing it to compress and securely grip the shaft when the bearing is driven up its tapered seat.
Common Applications
- Mining and Cement Industry: Used in large crushers, grinding mills, and conveyor drive pulleys where heavy bearings are common.
- Pulp and Paper Mills: Essential for mounting bearings on the large rollers found in paper machines.
- Power Generation: Applied in turbines, generators, and large industrial gearboxes that operate under high stress.
- Marine and Offshore: Suitable for propeller shafts and other heavy rotating equipment in marine propulsion systems.
- Steel Manufacturing: Utilized in rolling mills and continuous casting machines.
- Large Industrial Fans and Blowers: Provides reliable mounting for the main shaft bearings in large-scale ventilation systems.
Benefits of Using the H 3092 OH Sleeve
- Damage-Free Installation: The hydraulic method minimizes the risk of scoring or damaging the bearing bore and shaft surface during mounting and dismounting.
- Reduced Maintenance Time: Significantly speeds up the process of installing and removing large bearings, reducing machinery downtime.
- Enhanced Operational Reliability: Guarantees a correct and uniform interference fit, reducing vibration and increasing the service life of the bearing assembly.
- Simplified Assembly Process: Eliminates the need for heating bearings or using excessive mechanical force for installation.
- Cost-Effective Shafting: Permits the use of commercially available cylindrical shafts, avoiding the cost of precision-machined stepped shafts.
- Increased Safety: The controlled nature of hydraulic mounting is safer for technicians compared to methods involving heavy hammers or presses.
