Durability (Life) Durability comparison Cylinder with Lub-retainer Standard cylinder With heavy-duty scraper: -XC4 5 4 3 2 1 0 4 times stronger Dust (Foreign matter) Lub-retainers Grease film formation Piston rod (Reference) Comparison with the standard model and model with heavy-duty scraper (-XC4) (Relative ratio of B10) . The durability test is conducted in accordance with SMC test conditions. Even with the built-in stable lubrication function (Lub-retainer), the overall length and mounting are the same as those of the standard model. . Except for some models As the Lub-retainer is mounted at two locations, ! Grease film is formed on the piston rod surface to improve the durability. ! Entry of dust and foreign matter is prevented. ! The number of operating cycles can be improved even in general environments.
