SKF Felt Seal Ring with Aluminium and Nitrile Rubber Element, 75mm ID, 103.5mm OD TSN 517 C

SKF TSN 517 C Felt Seal Ring incorporates advanced materials including felt, aluminium, and nitrile rubber to offer high-performance axial sealing for rotating machine elements.

The assembly consists of a fibrous felt element serving as the primary seal, an aluminium ring delivering robust dimensional support, and a nitrile rubber lip that contacts the shaft to exclude contaminants. This construction improves service life in demanding environments by reducing abrasive wear and minimizing sealing failures.

With an inside diameter of 75mm and an outside diameter of 103.5mm, the TSN 517 C is optimized for standard rotary shaft installations in electric motors, gearboxes, and automation equipment. Its 10mm thickness allows for installation in space-constrained applications without compromising sealing efficiency.

Combines felt, aluminium, and nitrile rubber for efficient contaminant exclusion and lubricant retention. 75mm inner diameter and 103.5mm outer diameter suitable for standard rotary shaft arrangements. Thin cross-section minimizes axial space requirements in compact assemblies.

Provides structural stability and consistent sealing performance under mechanical stress. Compatible with electric motor shafts, gearbox inputs, and automation machinery. Felt material delivers primary sealing and metal support enhances dimensional integrity.

Nitrile rubber lip ensures dynamic contact with the shaft and resistance to mineral oils and industrial greases. Easy visual inspection enabled by uniform black colour and design characteristics.

Typical applications include sealing bearing housings in automation systems, rotary shafts in mechanical assemblies, and electric motor shaft seals. The nitrile rubber lip maintains compatibility with mineral oils and common greases, making it suitable for a variety of industrial lubrication environments. Its design offers extended maintenance intervals, reducing downtime in continuous operations.

Installation is straightforward, with uniform compression of the felt and visual alignment cues provided by the black elastomeric lip. This aids technicians in confirming correct seating and axial positioning during assembly.

Ideal for use in industrial, manufacturing, automation, and electromechanical systems where reliable axial sealing is necessary. Explore more sealing and gasket solutions from SKF and browse EnvMart for comprehensive component needs.
