Product Overview: The H 39/630 OH Hydraulic Adapter Sleeve
The H 39/630 OH is a large-scale hydraulic adapter sleeve, a crucial component from our OH 3900 Series, designed for securely mounting bearings with a 630 mm tapered bore onto a 600 mm cylindrical shaft. This sleeve simplifies the mounting and dismounting of large bearings by incorporating oil supply ducts and distribution grooves. By injecting oil under high pressure between the mating surfaces, the interference fit is overcome, allowing for effortless and precise positioning without the risk of damaging the bearing or the shaft. This makes it an indispensable part in heavy industrial applications where reliability and ease of maintenance are paramount.
As a key part of the Adapter Sleeves family, the H 39/630 OH assembly is typically completed with a corresponding lock nut and locking device. Its robust construction from high-grade steel ensures maximum grip and stability, providing a secure, concentric fit that is essential for the smooth operation of heavy machinery. Explore our comprehensive range of Sleeves to find the optimal solution for your bearing mounting needs.
Key Features of the H 39/630 OH
- Hydraulic Mounting/Dismounting: Features integrated oil ducts and grooves for easy, fast, and safe installation and removal using hydraulic pressure.
- Secure Fit: Creates a strong interference fit, ensuring the bearing is firmly fixed to the shaft and preventing fretting corrosion.
- Precise Positioning: Allows for accurate axial adjustment and positioning of the bearing on the shaft.
- Tapered Design: The 1:12 taper provides a reliable and solid mounting solution for bearings with a tapered bore.
- Durable Construction: Manufactured from high-quality steel to withstand high loads and ensure long-term operational reliability.
- Shaft Compatibility: Enables bearings to be mounted on plain or stepped commercial-grade shafts, offering design flexibility.
