4015.SDTSB90 (Telescopic slide) - SDTSB-90 (238-735 kg) Bi-Directional Front & Rear. Stainless Steel 316L

The SDTSB-90 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 mid-mounted train battery rafts, where access from either side may be limited.

This is a heavy load/duty full extension telescopic slide (238-735 Kg/pair) suitable for a wide range of applications. At 550mm 1 pair has a full extension load capacity of 672 kg. Constructed from milled stainless steel 316L sections, with machined ball tracks for accuracy, it has excellent levels of shock and vibration resistance. Accordingly, the product is well suited to supporting military truck drawers, offshore stowage and train battery boxes. 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.

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 extreme temperature use. Grade 316L is an austenitic stainless steel with a very low electro-magnetic signature, so ideal for defence applications.

SDTSB slides on accurate robotic pick & place or high speed shuttles require factory adaptation and customer in situ testing, prior to committing to production.  The beams are precision ground for accuracy and ball cages laser cut. However, constant low force usage will lead to some bearing migration without an operator to realign about every 2,000 cycles. The slides are limited to operational speeds of <0.3m/s. We are starting a laser hardening programme for the ball races, to launch in Jan 2024. This will increase the hardness to 62hrc, operational speeds to 0.7m/s and reduce the operational forces to traverse. This will make the slide ideal for robotic usage with a substantial economy over expensive induction hardened beams.

The slides are manufactured from milled stainless steel (inox) 316L. Standard ball cages are manufactured from stainless 316, and the ball bearings are 316L stainless steel. A single SDTSB-90 weighs 19.38 kg per metre.
