Product Overview: H 30/630 OH Hydraulic Adapter Sleeve
The H 30/630 OH is a high-performance hydraulic Adapter Sleeve designed for mounting bearings with a tapered bore onto cylindrical shafts with a 630mm diameter. As a key component in our Sleeves collection, it simplifies the installation and removal process, especially for large and heavy bearings. The 'OH' designation signifies that this sleeve is equipped with oil supply ducts and distribution grooves, enabling the use of the hydraulic method. This technique involves injecting oil under high pressure between the mating surfaces, which dramatically reduces the force required for mounting and dismounting, preventing damage to both the bearing and the shaft.
Part of the comprehensive OH Series, the H 30/630 OH comes complete with a corresponding lock nut and locking device to securely fasten the bearing in its final position. Its precision engineering ensures a reliable and concentric grip, essential for high-speed or heavy-load applications.
Key Features of the H 30/630 OH Sleeve
- Hydraulic Mounting & Dismounting: Features integrated oil ducts and grooves for easy, low-force installation and removal using the oil injection method.
- For 630mm Shafts: Specifically designed to locate bearings with a tapered bore onto a 630mm cylindrical shaft.
- Complete Assembly: Supplied as a set with a high-strength lock nut and a secure locking washer or clip.
- Simplifies Bearing Arrangement: Allows the use of simpler, straight cylindrical shafts, reducing overall machining costs and complexity.
- Precise Axial Positioning: Enables the bearing to be accurately positioned anywhere along the shaft.
