The innovative TLR slides ensure an extension that is equal to the closed slide, as well as a small constant. The motion of the intermediate element and the lower rail creates the extension, while the upper rail is fixed to the structure. The movement of the lower rail is larger than that of the upper rail owing to the optimisation of load capacity. This is also due to the rollers being located on the intermediate element to offer maximum load capacity in this position. As the TLR slides are asymmetric, they must be ordered as left side slide TLRS and right side slide TLRD. When installed, the product code must be located on the top side. The load capacities are indicated per rail, with centred load position, equal to half the rail in the extended position.
The TLR slides can prevent minor structural errors or non-precise installation when used in pairs. Usually this would increase the required force for moving the mobile part in the extending and closing direction, which is a common challenge for ball-cage telescopic slides.
However, using a pair of self-aligning TLR slides creates smooth, low friction movement and an easier installation, which results in cost savings.
The self-aligning feature is achieved with a combination of floating rollers and guiding rollers in the TLR..A (aligning). This allows for minor rail rotation and maintaining the preload in the upper and lower rails of the TLR..A slide.
The TLR..A is generally used as a pair with standard TLR for good lateral stability. Good self-aligning can also be achieved for movement of vertical panels with the use of TLR..A at the top to absorb some misalignment and with some retainer guidance at lower part.
