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.
We maintain stable bulk stock to support fast delivery and volume procurement for global aftermarket and industrial channels.
