Product Overview: The H 3188 OH Hydraulic Adapter Sleeve
The H 3188 OH is a high-performance hydraulic adapter sleeve designed for securely mounting bearings with a tapered bore onto 420mm cylindrical shafts. As a key component in our Adapter Sleeves category, this sleeve is part of the robust OH 3100 Series, which is distinguished by its integrated oil supply ducts. These ducts facilitate the use of the hydraulic method for mounting and dismounting large bearings, significantly reducing the effort required and minimizing the risk of damage to the bearing or shaft. The H 3188 OH assembly includes the sleeve, a lock nut, and a locking device, providing a complete solution for creating a secure and precise fit.
Engineered for heavy-duty applications, this hydraulic sleeve ensures a strong, concentric grip, allowing bearings to be positioned accurately on the shaft without the need for shoulders or other locating features. It is an indispensable component for industries that rely on large machinery, offering a reliable and efficient mounting system.
