Seals for General Industrial Applications
With a variety of designs and materials, SKF can offer shaft sealing solutions for almost any power transmission application. Examples include standard metric rubber outside diameter seals and low- friction seals with the SKF WAVE lip design. SKF also offers solutions with PTFE sealing lips, withstanding aggressive environments, high temperatures and pressures, as well as dry running.
Seals for Heavy Industry Applications
SKF seals for heavy industry are designed to work under tough operating conditions, such as high speeds and temperatures, while retaining the lubricant and excluding contaminants. Options include heavy-duty metal-cased seals, rubber outside diameter seals with metal inserts or fabric-reinforcement and all- rubber seals.
Fluid Power Sealing Systems
SKF offers a wide range of fluid power seals, designed to optimally work together in well-balanced sealing system solutions in a hydraulic cylinder. The assort- ment includes rod, piston and wiper seals as well as guides, O-rings and back-up rings. SKF fluid power seals are available in a multitude of materials to pro- vide optimal compatibility with the various hydraulic fluids encountered in service.
Machined Seals and Customized Sealing Solutions
Independently of improving an existing design or creating a new solution, SKF can help analyze the application requirements and then select/create the optimal sealing solution. Thanks to SKF SEAL JET manufacturing processes for machined seals, customers benefit from high flexibility and short delivery times for customized sealing solutions.
Designed for hub bearing arrangements typically found on com- mercial and off-road vehicle axles, SKF SCOTSEAL is a robust, customized sealing unit. All three different designs - Classic, Longlife and PlusXL - install easily and accommodate all driving conditions.
SKF SPEEDI-SLEEVE is a well-proven solution to fix worn shafts within minutes, providing an excellent sealing surface without having to disassemble the shaft or change the seal dimensions.The sleeve combined with an SKF radial shaft seal provides an enhanced sealing system, resulting in a consistent and increased operating durability. This improved service life predictability assists with maintenance planning. For large shafts, SKF can also offer wear sleeves for heavy industrial applications.
SKF Mudblock
SKF Mudblock cassette seals are radial shaft sealing units developed for heavy-duty applications in harsh environments. All SKF Mudblock seals are designed with an integrated wear sleeve, but can have any one of a number of sealing lip and auxiliary lip configurations. Their geometry provides excellent lubricant re- tention and optimum protection against water, dust, mud and other contaminants.
Metal Face Seals
SKF metal face seals HDDF are designed for severe operating conditions at relatively low circumferential speeds. HDDF seals consist of two identical metal sealing rings and two similar Belleville washers. Originally developed for off-road and tracked vehicles, the seals are also suitable for other applications exposed to sand, soil, moisture and more.
V-ring Seals
V-ring seals are all-rubber seals for rotating shafts. Featuring a conical-shaped sealing lip joined to the body with a resilient “hinge,” V-ring seals install directly on the shaft and rotate with it, retaining lubricants and excluding water spray and solid contaminants. They can also act as a grease valve. SKF offers V-ring seals in different designs, materials and sizes to meet most application requirements.
SKF Trackstar Seals
SKF Trackstar seals are track pin seals designed for oil-lubricated, off-highway track chains. Installed on the pin connecting a pair of chain links, SKF Trackstar seals feature a rubber energizer and a polyurethane sealing ring. There is also a heavy-duty design including a metal reinforcement ring moulded into the polyurethane sealing ring, providing additional rigidity for severe operating conditions.
