Roller telescopic slides for high-frequency, self-aligning
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.
Telescopic slides with ball-cage. Heavy Loads
The Ball-cage T RACE telescopic slides range are the most advanced ballcage slides. They offer the best ratio “capacity load / size” available on the market with the Superior smooth performance, thanks to its nitriding hardened raceways, assuring constant preload during full lifetime.
The black oxidation guarantees a high corrosion resistance unlike traditional zinc plated slides, which soon loose their preload, once soft zinc is consumed at ball contact points.
All the Series are available in the version “X” with high corrosion resistance. For this version the balls the cages and the screws are made in stainless steel (INOX ) and also the intermediate plate (when foreseen) for high corrosion resistance. The rails are standard with T RACE-NOX treatment.
All ball-cage telescopic are supplied with a standard preload that is between a light play to a light preload, obtained by selecting the right ball diameter from a large range of balls, with diameter differences of hundreds of mm. As both the rail and inner rail have minor tolerances also the preload has subsequently a small range of preload setting, i.e. between minor play to minor preload. Typically suitable for all standard applications.
Semi-telescopic slides, High Performance
The semi-telescopic slides SR allow for a stroke, equal to half the length of the slide, plus a minor stroke 10-25mm depending on type.
The slides can also perform an equal stroke to the other side, removing the small screw positioned at the left side.
The version KB for high corrosion resistance, have ballcage and balls bearing in INOX.
The load capacities are all referred to a single slide, with load at the centered position.
TELESCOPIC SLIDES COST EFFECTIVE
The TLAZ and TQAZ slides are made from robust rolled steel profiles and precision bearings, for smooth and precise moment along with interesting load capacities. The TLAZ comes with an intermediate element to offer higher load capacities than the TQAZ for the medium/ longer stroke versions.
These slides represent NUOVA T RACE’s most economical telescopic slides, but nothing compared with cheap furniture drawer-slides, based on ball-cage movement. The slides are for application where TLS/TSQ/TLR/TQL28 can’t meet the target price or where commercial drawer slides can’t meet the requested quality and smooth movement.
The slides are available in standard steel version and complete INOX versions: TLAX, TQAX. The INOX versions offer same performance as standard and with same dimensions. The slides offer a stroke equal to the length of the slide. The roller bearings are with 2Z seals and lubed for life. Thanks to high temperature grease, the TLAZ and TQAZ are also suitable for application with constant temperature of 170° celcius The slides comes all with strong damping rubber end-stops , which together with the rolling movement assure very silent function.
