General

SD-JS Slides

The SD-JS Series is a heavy duty linear slide with all metal, top of the line, rolling contact, precision ground ball screw and zero backlash ball nut in a SERVO READY package. Specify the motor to be used and we’ll supply the motor mounting adapter plate and servo coupling.

Stelron has been manufacturing high quality rolling contact slides in the U.S.A. since the early 1960’s. Rolling contact delivers higher efficiency and lower wear than the sliding contact bushings and lower grade screws by others. The results are higher load capacities and longer life.

Anti-Friction Slide Introduction:

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 stroked are not a limitation due to the use of re-circulating ball races in the bearing.

Application:

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 when the slide bar ends are fixed, thus permitting the housing to move.

Where 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.

Materials:

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 light grade oil. The standard use of felt wipers absorbs and distributes the lubricant, excludes most foreign matter and offers less resistance then Neoprene type seals.

The co-efficient of friction for the bearings without wipers is approximately .003.

Clearance:

All standard units have approximately .001 mean clearance between the shaft and bearing bores. Shafts providing a line to line fit can be supplied when specifically requested.

Capacity Ratings:

All standard units have approximately .001 mean clearance between the shaft and bearing bores. Shafts providing a line to line fit can be supplied when specifically requested.

Stroke Lengths:

Due to a large variation in desired stroke requirements, our facilities enable us to provide ANY length BELOW that tabulated for various units — longer lengths incur the additional cost of shaft over and above those tabulated.
