Product Overview: The H 2340 OH Hydraulic Adapter Sleeve
The H 2340 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a 200 mm tapered bore onto a 180 mm cylindrical shaft. As a crucial component in our Adapter Sleeves range, this sleeve simplifies the installation and removal of large bearings, particularly in heavy-duty applications. The 'OH' designation signifies its hydraulic capabilities, featuring oil supply ducts and connections that allow for the use of a hydraulic pump. This method injects oil under high pressure between the mating surfaces, creating an oil film that dramatically reduces friction and the force required for mounting and dismounting, preventing damage to both the bearing and the shaft.
Part of the H 2300 Series and OH Series, the H 2340 OH ensures a secure and precise fit, enabling the use of standard commercial shafts and simplifying the overall machine design. It is supplied as a complete assembly, typically including a hydraulic nut and necessary seals, providing a comprehensive solution for demanding industrial environments.
Key Features of the H 2340 OH Sleeve
- Hydraulic-Assisted Mounting: Integrated oil ducts allow for hydraulic pressure to be applied, simplifying the installation of large bearings with minimal effort.
- Effortless Dismounting: The hydraulic method makes removing the bearing equally straightforward, significantly reducing maintenance time and labor.
- Prevents Component Damage: Eliminates the need for excessive force or hammering, protecting the precision-ground surfaces of the bearing and shaft from damage.
- Secure Clamping: The sleeve's tapered design provides a powerful and concentric grip on the shaft when the lock nut is tightened, ensuring reliable performance under heavy loads.
- Precision Engineering: Manufactured from high-strength steel to strict tolerances for optimal fit and durability.
- Cost-Effective Design: Allows bearings with a tapered bore to be used on less expensive, cylindrical shafts without the need for a locating shoulder.
Common Applications
- Mining and Quarrying: Used in crushers, conveyors, and vibrating screens where large bearings are subjected to extreme loads and vibration.
- Pulp and Paper Mills: Ideal for mounting bearings on felt rolls, drying cylinders, and other large rotating machinery.
- Steel Manufacturing: Essential for equipment like rolling mills and continuous casters that require robust and reliable bearing arrangements.
- Large Industrial Fans and Blowers: Ensures secure mounting of bearings on fan shafts, critical for high-speed and continuous operation.
- Marine and Offshore: Applied in propulsion systems, winches, and cranes where reliability and ease of maintenance are paramount.
- Cement Plants: Used in kilns, grinding mills, and large gearboxes that handle heavy materials and operate in harsh conditions.
Benefits of Using the H 2340 OH Sleeve
- Reduced Maintenance Time: Hydraulic assistance dramatically speeds up the bearing installation and removal process, minimizing equipment downtime.
- Enhanced Safety: Eliminates hazardous traditional mounting methods like heating or using heavy striking tools, creating a safer work environment.
- Improved Reliability: Provides a rigid and accurate mounting, ensuring the bearing operates correctly and achieving its maximum service life.
- Simplified Logistics: Allows for the use of readily available cylindrical shafts, reducing the need for custom-machined stepped shafts.
- Extended Component Life: The damage-free mounting and dismounting process preserves the integrity of the bearing and shaft for future use.
- Precise Positioning: Enables the bearing to be accurately positioned anywhere on the shaft without the need for shoulders or locating rings.
