CR Seals are radial and axial shaft sealing solutions for power transmission applications supports virtually every industrial sector, from large-size wind turbines to very small, high-speed machine tools. For off-highway applications, we offer undercarriage sealing solutions for wheeled equipment, which include SKF Mudblock cassette seals and the innovative SKF Trackstar seals for tracked machinery.

The design of SKF Mudblock cassette seals has been optimized to provide excellent retention of either grease or oil and maximum protection against liquid or solid contaminants. The seals are made to order to meet the demands of each specific application.

To seal efficiently, radial shaft seals must run against a smooth, round counterface. If the counterface becomes worn, the seals will no longer be able to fulfill their function, which is to retain lubricant and exclude contaminants.

The basic SKF Trackstar seal design features a polyurethane sealing ring and a nitrile rubber energizer (fig 1). The sealing ring retains the oil between the pin and the bushing and excludes contaminants. The energizer provides the static sealing ability.

SKF metal face seals type HDDF (fig 1) are designed for use under severe service conditions at relatively low circumferential speeds. They offer reliable protection against solid and liquid contaminants as well as leak-proof retention of lubricants.

V-ring seals are axial shaft seals, available in a wide range of stock sizes and customized solutions for sizes above 2 000 mm or special requirements. SKF supplies also metal-cased V-ring seals

SKF axial clamp seals are designed for large and very large shaft diameters. SKF axial clamp seals are made of profiled strips of non-reinforced nitrile rubber and are held firmly in position

SKF is the global market and technology leader custom engineered sealing solutions offering a comprehensive range of machined seals for many industries.
