The STELRON ANTI-FRICTION SLIDE units incorporate tried and proven linear ball bearings into compact assemblies combining rolling elements for low friction, hardened contact surfaces for long life and minimum wear, with negligible or zero backlash. Long, unrestricted strokes are not a limitation due to the use of re-circulating ball races in the bearings.
Integral felt wipers are normally supplied on all units to reduce frictional drag, exclude foreign matter and distribute lubricant. However, units can be supplied with neoprene type seals when requested.
Machine parts or tools which require "in-line" motion can be readily mounted to the STELRON ANTI-FRICTION SLIDE units either on the surfaces provided at the slide bar end plates, or on the housing to move. When translational or incremental movement in a plane with the sensitivity and accuracy of a ball bearing is required, the STELRON X-Y ANTI-FRICTION SLIDES fulfill a wide range of applications.
Shafts are hardened and ground steel. End plates and housings are generally steel except in larger sizes where aluminum is used to reduce weight.
With few exceptions, all external surfaces are ground. Housings and end plates have black oxide or anodized surface treatment.
LUBRICATION & FRICTION:
Integral oil cups are usually provided for application of a light grade oil. The standard use of felt wipers absorbs and distributes the lubricant, excludes most foreign matter and offers less resistance than Neoprene type seals. Whereas the co-efficient of friction for the bearings without wipers is approximately .003.
All standard nits have approximately .001 mean clearance between bores. Shafts providing a line to line fit can be supplied when specifically requested.
Due to a large variation in desired stroke requirements, our facilities enable us to provide ANY length BELOW that tabulated for the various units-longer lengths incur the additional cost of shaft over and above those tabulated.
