Product Overview: The H 3284 OH Hydraulic Adapter Sleeve
The H 3284 OH is a high-quality adapter sleeve designed for securely mounting bearings with a tapered bore onto cylindrical shafts with a 420mm diameter. As a key component in our Adapter Sleeves range, it simplifies the installation and removal process, particularly in large-scale industrial machinery. This sleeve is part of the OH 3200 Series, which is specifically engineered with oil supply ducts to facilitate hydraulic mounting and dismounting. This method significantly reduces the time and effort required for fitting large bearings, preventing damage to both the bearing and the shaft.
Manufactured from robust materials, the H 3284 OH adapter sleeve provides a reliable and rigid connection, ensuring optimal performance and longevity of the bearing assembly. The package includes the slotted sleeve, a corresponding lock nut, and a lock washer, providing a complete solution for locating bearings accurately on a shaft. It is an indispensable component for applications where precision and ease of maintenance are critical.
Key Features of the H 3284 OH Sleeve
- Hydraulic Mounting Capability: Features integrated oil ducts (OH designation) for easy and safe hydraulic mounting and dismounting, ideal for large bearings.
- Complete Assembly: Supplied as a complete set including the slotted sleeve, a high-strength lock nut, and a secure lock washer.
