Product Overview: The H 3138 OH Hydraulic Adapter Sleeve
The H 3138 OH is a high-performance adapter sleeve specifically designed for mounting bearings with a 190 mm tapered bore onto a 170 mm cylindrical shaft seat. As a critical component in our Adapter Sleeves range, it simplifies the process of securely locating bearings on stepped shafts. The 'OH' designation indicates that this sleeve is equipped with oil supply ducts and distribution grooves, enabling the use of the hydraulic oil injection method for effortless mounting and dismounting. This feature significantly reduces the risk of damage to the bearing and shaft, making it ideal for large and heavy-duty applications.
This sleeve is part of the robust OH 3100 Series and is supplied as a complete set, including a high-quality lock nut and lock washer. This ensures a secure and reliable assembly, preventing loosening from vibration or operational stresses. By allowing the use of commercial-grade shafting, the H 3138 OH provides a cost-effective and efficient solution for demanding industrial environments.
Key Features of the H 3138 OH Sleeve
