SK inear Guides for Contaminated nvironments SK s advanced, high-performance seal dramatically reduces the entry of fine contaminants to less than one-tenth of existing products and provides five-times longer service life. Patent Pending
ith dramatically improved sealing performance, the delivers outstanding functionality and long operating life under contaminated environments. SK linear guides are designed to dramatically improve sealing capability for machinery such as equipment used for woodworking and graphite milling, which is exposed to fine particles and requires protection against the entry of fine contaminants. y adopting high-performance seals and the proven, the reduces the entry of fine contaminants into ball slides to less than one-tenth of existing products and realizes outstanding lubrication performance. Operating life is five times longer in dusty environments. As a result, the linear guides are extremely reliable and demonstrate excellent capability in contaminated environments. eatures SK inear Guides for Contaminated nvironments Applications oodworking machines Graphite milling machines uff polishers for tires aser cutting machines elding lines Conveyers and others (optional) High-performance end seal Structure of Comparison with SK standard products: ess than 1/ the level of fine contaminants Results of dust-proof tests reveal that the entry of fine contaminants is reduced to less than one-tenth of existing standard series due to improvements in sealing capability. est conditions Specimen Speed oreign matter VH30A 16.7 mm/sec Graphite powder (average grain size: 0.037 mm) and Grease Operating life under contaminated environments is more than times longer 5 Durability test with rubber fragments xtreme durability tests under contaminated environments using rubber fragments show that durability of the V1 Series extended more than five times longer than the existing standard series, as shown in the graph.

Permissible temperature range Maximum operating temperature: 50 C Maximum instantaneous peak temperature: 80 C 2. Chemical precautions ever leave the linear guide near grease-removing organic solvents such as hexane or thinner. ever immerse the the linear guide in kerosene or rust preventive oils which contain kerosene. Carefully remove ball slides from the rails, as the balls can fall out. hen the rails are tilted without the stopper, the ball slides may move along the rail and fall out. hen ball slides are used upside down (for example, when the rails are attached to the ceiling with the ball slides down), take special precautions such as installing a safety device to prevent the ball slides from falling. 4
