Product details

This 58×70×7.5/7mm TB type oil seal is a universal metal cased rotary shaft sealing solution, widely applied in automotive auxiliary shafts, agricultural machinery, industrial motors and general hydraulic equipment. It features an exposed cold rolled steel outer case for rigid mounting and stable positioning in the housing bore, paired with a precision machined NBR sealing lip and an integrated carbon steel garter spring. The spring maintains consistent radial preload on the shaft surface to ensure reliable sealing performance under continuous rotation and vibration. It effectively retains lubricating oil and grease inside the housing, and blocks external dust and impurities from invading internal components. Manufactured under ISO/TS 16949 quality management system with strict dimensional tolerance control, it is a direct replacement for standard industry size seals. We maintain stable bulk stock to support fast delivery and volume procurement for global aftermarket and industrial channels. Core value for buyers Standard industry interchange dimensions, direct drop in replacement Rigid metal case for secure press fit installation Cost effective factory direct pricing for bulk sourcing Stable quality consistency for repair and maintenance

Selection guide

Selection Guide 1. Confirm shaft ID 58mm, housing OD 70mm, required thickness 7.5/7mm and TB metal case structure. 2. Standard NBR version for general working conditions ( 30℃ 120℃); select FKM upgrade for high temperature and chemically aggressive environments. 3. For volume procurement projects, contact us for exclusive bulk pricing. Installation Steps Surface Preparation Thoroughly clean the housing bore and shaft surface, remove old seal residue, dirt, rust and burrs. Pre lubrication Apply matching lubricating oil or grease evenly on the sealing lip and shaft mating surface. Dry installation is strictly prohibited. Orientation Confirmation The sealing lip faces the lubricant cavity side; the metal case open end faces outward. Press fit Installation Use a dedicated press tool to press the seal in evenly and vertically. Never strike the seal directly to avoid deformation and lip damage. Post installation Check Ensure the seal sits fully flush inside the housing bore without tilt. Inspect the sealing lip for nicks and scratches.
