SKF Felt Seal Ring Seal with Aluminium and Nitrile Rubber Element, 70 mm ID, 98.5 mm OD, 10 mm Thickness TSN 516 C

The SKF TSN 516 C is a felt seal ring seal combining a fibrous felt sealing surface with aluminium and nitrile rubber elements for industrial sealing applications. It features a 70 mm inside diameter, 98.5 mm outside diameter, and 10 mm thickness, designed to protect bearing assemblies and mechanical interfaces from particulate contamination and maintain lubricant retention.

The felt element effectively resists dust and scuffing, while the anodised aluminium backing ensures dimensional stability under operational stresses. The nitrile rubber component provides elastic compression to maintain contact pressure and compatibility with common industrial oils. This composite structure minimizes contamination ingress, extending the lifetime and reliability of rotating electrical and mechanical equipment.

This ring seal is specifically suited for sealing bearing housings in automated machinery and serves as an ideal maintenance replacement part for rotating electrical assemblies and mechanical drives in production lines. Installation requires matching the seal’s inside diameter snugly to the shaft journal, with the external aluminium support seating evenly within the housing counterbore.

Periodic inspection is advised to replace the seal when wear or loss of elasticity is evident, preventing failure from contamination ingress. The black finish on the seal reduces degradation from light-induced damage, making it suitable for exposed locations.

The felt sealing element resists dust ingress and scuffing during operation. Aluminium backing offers dimensional stability and robust structural support. Nitrile rubber component provides elastic compression and oil resistance.

Designed for 70 mm ID and 98.5 mm OD shafts and housings. 10 mm section thickness offers effective contact pressure control. Black finish reduces light-induced wear in external applications. Commonly used in industrial automation, manufacturing, electrical, and mechanical equipment.

Recommended for use in bearing housing sealing and mechanical drive retrofitting. Periodic maintenance ensures longevity and contamination protection. Explore more SKF sealing solutions and industrial-grade components at EnvMart for reliable equipment maintenance and performance.
