Specific features The standard slides are fitted with limited-stroke rail guides, with cross roller units. Permissible speed and acceleration The rail guides can run at speeds up to 2 m/s and accelerations up to 10 m/s2 are acceptable. Preload Preload is applied by set Screws fitted along one side of the slide top. The standard slides are preloaded to approximately 10 % of the static load rating.

Materials GCL Standard slides • slide top and base: blackened steel or GG25 (cast iron), depending on size For all slides • guide rails: tool steel 90MnCrV9 (1.2842) hardened • rolling elements: carbon chromium steel 100Cr6 (1.3505) hardened • cage: plastic PA12 or aluminium, depending on size Permissible operating temperature –30 °C to +80 °C

Friction The slides are free from stickslip. With normal light lubrication they have a coefficient of friction of between 0,003 and 0,005. Lubrication Rail guides of standard slides are lightly greased on assembly with SKF LGMT2 grease, a multi-purpose lithium based grease which also serves as protection against corrosion. It can be used in all standard applications.
