General

SSP Series:

Due to the widespread acceptance of the DS and SS units, the SSP Series anti-friction slide has been introduced to make available a less expensive, flexible unit for those installations which do not require the non-rotating feature of the SS unit.

Retaining the advantages of integral felt wipers, identical housing dimensions and mounting holes of the SS Series, these units provide the designer with wide latitude in adapting them to a particular application.

The shaft ends have central tapped holes to permit the mounting of accessory tools, actuating links or other appropriate machine members.

Rotation of the shaft is not recommended, but may be used with caution under light duty service conditions.

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.
