The SDTSB-70 offers total extension front and rear. This is made possible by an internal rocker device which releases each beam in sequence. Ideal for thru-truck drawers or train battery boxes where access from either side may be limited. This is a heavy load/duty full extension telescopic slide (154-540 kg/pair) suitable for a wide range of applications. At 550mm 1 pair has a full extension load capacity of 490 kg.

Constructed from milled stainless steel (inox) 316L sections, with machined ball tracks for accuracy, it has excellent levels of shock and vibration resistance. Accordingly, the product is well suited to operating in extreme high temperatures through to as low as cryogenic. The slide beams, cages and ball bearings are manufactured from austenitic grade 316L (1.4404). End stop bolts and retaining pins are austenitic grade 304 (1.4301), completing the corrosion protection, There is the bespoke option to manufacture an all 316L product on higher production volumes.

The beam release mechanism guarantees that one beam is held firm whilst the other travels. Unlike some systems where the load is pulled through the slide and the ball cages misalign and jam.

Due to the extreme strength of the mobile 'I' beam, this slide is robust to applied loads when in the extended position making it an excellent choice for dynamic applications. Unlike many other slides manufactured from rolled steel 'C' sections. There are no plastic parts in the manufacture of this range, making it ideal for high temperature use. Grade 316L is an austenitic stainless steel with a very low electro-magnetic signature, so ideal for defence applications.

We do not recommend standard SDTSB slides on accurate robotic pick & place or high speed shuttles, without factory adaptation and customer in situ testing, prior to committing to production. The slides are limited to operational speeds of <0.3m/s.

Our Saibo TDB-43LK Robotic Bi-directional slide is designed for robotic pick & place and high speed shuttles, with operational speeds up to 0.8m/s. Interchangeable with other European manufacturers at substantially lower cost.

The SDTSB-70 drawer slide may also be fitted in the minor axis (flat). However, the load capacity will be reduced by 60-80% of the stated loading. A single SDTSB-70 weighs 13.42 kg per metre.

Please allow 4-5 weeks for manufacture, unless subscribed to our stock holding programme which facilitates next day supply.
