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.
