Selfalignment high performance telescopic cam roller slides

Roller Telescopic Slides TLR & TLRX

 The TLR slides are the world's only telescopic slides system which incorporated self-aligning feature to absorb parallelism errors of the mounting surfaces, when used in pairs.

The TLR slides are designed for heavy duty High-Tech telescopic applications, with precise motorized movement, requiring constant smooth sliding performance with no play. Recommended for high frequency applications.

The high performance is provide by use of double-row precision bearings, strong rails with hardened and honed raceways, fixed to a rigid intermediate S-shaped steel plate, assuring high load capacities and low flexion at even fully extended position. The TLR slides guarantee maintenance free operation, thanks to strong raceway wipers and longitudinal seals for dust and impurity protection. An integrated lubed for-life greasing system, assuring a constant thin layer of lubrication on the raceway surfaces, for a long operation period.

TLR system offers unique possibilities and benefits for all kind of automation applications with variable strokes, for which a ball-cage slide often has ball-cage creeping problems, i.e. friction problems to reach full extension, as ball-cage is forced out to end position, instead of rolling.

TLRX slides for corrosive ambients

For corrosive ambients is available TLRX, with all components and intermediate element in stainless steel,
except the rails, which have T RACE-NOX anti-corrosion treatment; a oxidation treatment and impregnation in hot oil, to offer a good corrosion resistance.
Extension

The TLR slides allow for an extension equal to the closed slide plus a small constant. The extension is obtained by movement of the intermediate element and the lower rail, while the upper rail is fixed to structure. As it can be seen on left figure, the movement of the lower rail is more than the upper rail, due to optimizing of load capacity and the fact that the rollers are positioned on the intermediate element to offer max load capacity in this position. Hereby the TLR slides are asymmetric, so the slides must be ordered as left side slide TLRS and right side slide TLRD and when installed the product code must be on top side.

Self-aligning capacity

When TLR slides are used in pairs, they offer the possibility to absorb minor structural errors or non-precise installation, which otherwise would much increase the required force for moving the mobile part, in both extending and closing direction. A typical problem for ballcage telescopic slides.

Using a pair of self-aligning TLR slides, smooth low friction movement is assured, along with a more easy installation and/or less precise workings of structure, i.e. cost savings. The selfaligningfeature is obtained by having a combination of floating rollers and guiding rollers in the TLR..A. i.e. allowing for a minor rotation of the rails, maintaining the preload in both upper and lower rails of the TLR..A slide.
