SKF SPEEDI-SLEEVE is a wellproven solution to overcome problems with worn shafts without having to disassemble the shaft or changing the seal dimensions, while offering an excellent sealing surface. Now, SKF has developed a new generation SKF SPEEDISLEEVE with features providing an even further enhanced sealing system performance. Using SKF SPEEDI-SLEEVE, combined with an SKF radial shaft seal, customers will benefit from a more consistent and increased durability of the sealing system. This will enable a more stable maintenance planning with improved predictability of the system service life. SKF SPEEDISLEEVE is available for shaft diameters up to approximately 203 mm (8 in.).
SKF SPEEDI-SLEEVE Gold is an enhanced version of standard SKF SPEEDI-SLEEVE, offering improved resistance to abrasive wear. Designed for applications where extended sealing system life is needed, SKF SPEEDI-SLEEVE Gold bridges the performance gap between the standard sleeve and expensive custom shaft treatments.
Radial shaft seals are used between rotating and stationary machine components or between two components in relative motion and consist of two main parts. Radial shaft seals are used in a multitude of applications. Because of the importance of radial shaft seals for the operational reliability and service life of machines and equipment, both seal manufacturers and users are equally interested, to some degree, in standardization. SKF metric rubber outside diameter radial shaft seals, HMS5 and HMSA10, are designed in accordance with ISO 6194-1 and DIN 3760 for use in a wide range of industrial applications. The available size range of HMS5 and HMSA10 seals includes a full coverage of the ISO 6194-1 and DIN 3760 dimensions for shaft diameters up to 250 mm
The SKF track pin seals, SKF Trackstar, are specifically designed for oil lubricated track chains in off-highway applications. The seals are installed on the pin that connects a pair of links in the chain. The basic SKF Trackstar seal design features a polyurethane sealing ring and a nitrile rubber energizer. SKF Trackstar seals provide several important benefits including:
• extended service life of the undercarriage
• reduced internal bushing and pin wear
• easy installation
• interchangeability with the most commonly used sealed and lubricated track pin seals
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. SKF Mudblock seals are widely used in wheelend applications such as the front and rear axles of, for example:
• agricultural machinery
• construction equipment
• forestry equipment
• off-highway trucks
SKF metal face seals type HDDF 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. Metal face seals are often used in heavily contaminated environments, where mud packing in the cavity between the housing, sealing rings and Belleville washers can occur.
