Product details

This 58×70×7.5/7mm TB type oil seal is a standard universal exposed metal case rotary shaft sealing solution, widely applied across automotive, agricultural and industrial fields. As a classic metal case oil seal, the TB type design features an exposed cold rolled steel outer case for rigid press fit mounting and stable positioning in the housing bore, paired with a precision machined NBR sealing lip and integrated carbon steel garter spring. The 58x70mm oil seal delivers reliable sealing performance under continuous rotation and mechanical vibration. The NBR rubber lip maintains excellent compatibility with petroleum based lubricants, hydraulic oils and general greases, while the garter spring provides consistent radial preload on the shaft surface to compensate for lip wear over time. This small size oil seal effectively retains lubricating oil and grease inside the housing, and blocks external dust and light impurities from invading internal components. As a standard industrial size, this TB type oil seal is interchangeable with same spec seals from most global manufacturers. Produced with strict dimensional tolerance control and mature vulcanization technology, it is suitable for both original equipment supporting and aftermarket replacement. We maintain bulk stock of standard sizes to support fast delivery and volume procurement for global distributors and industrial buyers. Core advantages for buyers Universal standard 58x70mm size, direct drop in replacement for same spec applications Exposed metal case structure for secure mounting and stable sealing performance Premium NBR compound, excellent oil resistance and wear resistance for long service life Factory direct pricing, cost effective for bulk sourcing and maintenance stock

Please confirm shaft diameter, housing bore size and seal thickness before ordering. Dimension mismatch will cause lubricant leakage after installation.

Selection guide

Selection Guide 1. Confirm shaft ID 58mm, housing OD 70mm, required thickness 7.5/7mm and TB exposed metal case structure. 2. Standard NBR 70 Shore A is suitable for most general oil and grease applications within 30℃ 120℃. 3. For high temperature or strong chemical conditions, select FKM material upgrade. 4. For volume project requirements, contact us for exclusive bulk pricing. Installation Steps Surface Preparation Thoroughly clean the installation housing bore and shaft surface, remove burrs, dirt, old seal residue and impurities. Pre lubrication Apply compatible lubricating oil or grease evenly on the sealing lip and shaft surface to avoid lip cutting during installation. Installation Press the seal into the housing bore evenly with a dedicated installation tool, keep it perpendicular to the shaft. Avoid hitting the seal directly with hard tools. Post installation Check Confirm the seal is properly seated in the groove without tilting, and the sealing lip is not twisted or damaged.
