Series MVR and CT
Metal-clad V-type sealing rings act as flingers and protect primary seals against coarse contaminants, dust and water spray, which considerably extends reliability and service life of sealing arrangements.
MVR metal-clad V-type sealing rings from SKF consist of a metal case, which house a body and a conical shaped axial sealing lip of nitrile rubber. The corrosion-resistant metal case protects the elastomeric sealing lip against mechanical effects from the outside. The seal has a tight fit on its seating and withstands speeds up to 12 m/s without auxiliary clamping devices.
MVR metal-clad V-type sealing rings are available for shaft diameters from 10 to 200 mm and can be used at temperatures between –30 and +100 °C.

SKF axial clamp seals are designed for large and very large diameters. They do not rotate but seal axially against a rotating counter face.
These CT design axial clamp seals are made of appropriately profiled strips of non-reinforced nitrile rubber (NBR) and are held firmly in position by stainless steel screw-type clamps. Axial clamp seals are available in the diameter range from 150 up to 4 600 mm (6 up to 181 inch) and are produced in three different designs:
CT1: Axial clamp seal with a flat face axial sealing lip. It permits an axial displacement with respect to the counter face of +2,4 mm.
CT3: Axial clamp seal with a flat face axial sealing lip but provided with annular grooves. These grooves serve to trap contaminants, which may have started to penetrate the lip/counter face contact. CT3 axial clamp seals permit an axial displacement with respect to the counter face of +4,8 mm.
CT4: Axial clamp seal with flat sealing lip as for the CT1 design, but with an extra wide body, which has to held in position by two clamps. It permits an axial displacement with respect to the counter face of +4,8 mm.
