Selection guide
Selection Guide for Bulk Buyers 1. Confirm shaft ID 150mm, housing OD 180mm, required thickness 15/16mm and TC double lip structure. 2. Standard NBR version for normal operating conditions ( 20℃ 120℃); select FKM upgrade for high temperature and chemically aggressive environments. 3. For fleet or bulk projects, free technical consultation on seal selection and installation is available on request. Installation Steps Surface Preparation Thoroughly clean the housing bore and shaft surface, remove old seal residue, dirt, rust and metal burrs. Pre lubrication Apply matching gear oil or bearing grease evenly on the sealing lip and shaft mating surface. Dry installation is strictly prohibited as it will cause premature lip wear and failure. Orientation Confirmation The primary sealing lip faces the lubricant cavity; the dust proof lip faces the external environment. Reverse installation will cause oil leakage and loss of dust protection. Press fit Installation Use a dedicated press sleeve tool to press the seal in evenly and vertically. Never strike the rubber body directly to avoid seal deformation and lip tearing. Post installation Check Ensure the seal sits fully flush in the housing bore without tilt or offset. Inspect the sealing lip for nicks and the seal body for deformation. Function Test Manually rotate the shaft assembly to confirm smooth rotation without abnormal binding resistance.
