Product Overview: The H 3276 OH Hydraulic Adapter Sleeve
The H 3276 OH is a high-performance hydraulic adapter sleeve designed for mounting bearings with a tapered bore onto 380mm cylindrical shafts. As a key component in our Adapter Sleeves collection, and specifically part of the OH 3200 Series, this sleeve simplifies the mounting and dismounting of large bearings through the use of hydraulic pressure. The 'OH' designation indicates that the sleeve is equipped with an oil supply duct and distribution grooves, allowing for the oil injection method. This technique significantly reduces the force required for installation and removal, preventing damage to the bearing and shaft.
Manufactured to precise industry standards, the H 3276 OH adapter sleeve provides a secure and reliable fit, ensuring that bearings are correctly positioned and held firm during operation. It is an essential accessory for heavy-duty applications where maintenance efficiency and component longevity are critical. This sleeve is typically used with large Spherical Roller Bearings in demanding industrial environments.
Key Features of the H 3276 OH
- Hydraulic Mounting/Dismounting: Features integrated oil supply ducts and grooves for the oil injection method, simplifying the handling of large bearings.
- Secure Clamping: Provides a strong, uniform grip on the shaft, ensuring the bearing is firmly located and preventing fretting corrosion.
- Tapered Design: The sleeve's tapered outer surface perfectly matches the tapered bore of the bearing, creating a precise interference fit.
- Complete Assembly: Designed to be used with a corresponding lock nut and lock washer (sold separately) to secure the bearing axially.
- Versatile Positioning: Allows the bearing to be positioned at any point along a plain cylindrical shaft, offering design flexibility.
- Simplified Shaft Requirements: Eliminates the need for expensive shoulders, keyways, or special machining on the shaft, reducing overall costs.
Common Applications
- Mining and Quarrying Equipment: Used in crushers, grinding mills, and conveyors where bearings are subject to heavy loads and harsh conditions.
- Pulp and Paper Industry: Ideal for mounting bearings on large rollers in paper machines, where easy dismounting is crucial for maintenance.
- Heavy-Duty Fans and Blowers: Ensures secure mounting of large bearings in industrial ventilation and air handling systems.
- Marine Propulsion Systems: Applied in propeller shafts and gearboxes to facilitate reliable and maintainable bearing arrangements.
- Steel and Metal Rolling Mills: Used to mount large work roll and back-up roll bearings that require periodic replacement.
- Large Gearboxes and Transmissions: Provides a robust solution for securing bearings on shafts in industrial power transmission systems.
- Construction Machinery: Employed in heavy equipment like excavators and cranes for mounting critical rotational components.
Benefits of Using the H 3276 OH
- Reduced Installation Time: The hydraulic method is significantly faster and requires less physical effort than traditional mechanical mounting techniques.
- Damage-Free Removal: Oil injection allows the sleeve to be removed without damaging the bearing or the shaft seat, preserving valuable components.
- Enhanced Operational Safety: Minimizes the risks associated with using heavy tools like sledgehammers and pullers during maintenance.
- Lower Maintenance Costs: Speeds up bearing replacement, reduces machinery downtime, and extends the life of associated components.
- Improved Reliability: Ensures a consistent and correct interference fit, leading to optimal bearing performance and reliability.
- Cost-Effective Shafting: Allows for the use of commercially available plain shafts, simplifying manufacturing and reducing inventory costs.
