E. Longmeadow, Massachusetts – LM76 has added a new series of 100% extension rails to its extensive product line of linear motion components and complete linear motion systems. The exclusive distributor of SAIBO Linear Motion Systems in the US, LM76 is now offering the SAIBO TDB28 and TDB43 series of Telescoping Extension Rails. Stroke lengths (extension) are 100% of the length of the assembly.

The TDB28 series of telescoping extension rails consists of 14 rails with stroke lengths from 148mm (5.827") to 1,202mm (47.323") and supporting loads from 472N (106 lb) to 1,018N (229 lb) when two rails are mounted in parallel and the load is uniformly distributed between the rails.

The TDB43 series of telescoping extension rails consists of 23 rails with stroke lengths from 246mm (9.685") to 2,026mm (79.764") and supporting loads from 1,212N (272 lb) to 2,414N (543 lb) when two rails are mounted in parallel and the load is uniformly distributed between the rails.

The TDB28 and TDP43 telescoping extension rails are created using a C-shaped external rail and an internal slider. Two rows of steel ball bearings (one on the top and bottom of the slider) travel in ball cages on hardened V-shaped ways with four points of contact. Assembled with a zero clearance, the compact, precision, smooth sliding rails are designed for applications such as: delicate parts transfer, assembly, testing, laser machining and drilling, wafer handling, and rail and rack systems for components in autonomous vehicles, aircraft, trains, ships, and trucks.

Both the TDB28 and TDB43 100% Full Extension Rails have a maximum working speed of 0.8 m/sec. and have an operating temperature range of -20°C to 120°C.
