NTN Domestic Steel Round Adapter Sleeve With Lockwasher, H303 Series

NTN Domestic Steel Round Adapter Sleeve With Lockwasher, H303 Series adapter sleeve with a lockwasher is a mechanical component used in machinery to secure bearings onto shafts. The adapter sleeve is a cylindrical component with a tapered bore that fits over the shaft, allowing for easy installation and removal of bearings. The lockwasher, typically made of spring steel, is placed on the threaded portion of the adapter sleeve and acts as a locking mechanism to prevent the sleeve from loosening due to vibration or axial movement.

When installing a bearing onto a shaft using an adapter sleeve with a lockwasher, the sleeve is first slid onto the shaft and positioned at the desired location. The bearing is then mounted onto the sleeve, and the lockwasher is placed onto the threaded end of the sleeve. Finally, a nut is threaded onto the sleeve, compressing the lockwasher against the bearing, creating a secure connection.

This setup provides a reliable and durable method for mounting bearings onto shafts, ensuring proper alignment and reducing the risk of loosening or damage during operation. The lockwasher adds an extra layer of security, making it suitable for applications where vibration or axial forces are present.
