SDTSB-50 Stainless 316L (70-294 kg/pr) Full Ext’n Bi-Direction

Description

Professional Range slides are sold as singles, so order two units if a pair is required

The SDTSB-50 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 where access from either side may be limited.

This is a heavy load/duty full extension telescopic slide (70–294 kg/pair) suitable for a wide range of applications. At 550mm 1 pair has a full extension load capacity of 287 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 battery boxes, generators and external pods which are working in corrosive environments. 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. Grade 316L is an austenitic stainless steel with a very low electro-magnetic signature, so ideal for defence applications.

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.

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 SDTSB-50 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-50 weighs 8.92 kg per metre.

The SDTSB-50 can be purchased online for global delivery. Please allow 5-6 weeks for manufacture, unless subscribed to our stock holding programme which facilitates next day supply.
