The EPG roller chain meets or exceeds ANSI standards and is manufactured in ISO certified factories. As is the case with our pillow block bearings and ball bearings, our roller chain parts are tested prior to shipment to insure quality. The roller chain parts and roller chains we supply are pre-stretched to insure you have limited sag. It also comes with solid rollers, ensuring that it is of the highest quality.ensures the stability and consistency of the key function of comp1nts.Standard strands have an even number of pitches, pin links, and roller links. A roller chain & sprocket strand can be shortened by removing links and lengthened by adding whole or a half links (offset links).Rosta 61030000 25BB20 idler sprocket for SE1110si1rs is manufactured to ANSI and ISO standards and is made from high-quality steel. It has 20 teeth and runs #25 roller chain & sprocket for size SE 1110si1rs. For more information or to get a quote please contact us and we will be happy to assist you!

Mounting Instructions for Chain & Sprocket Drives
The ROSTA10sioning device should be placed on the slack side of the chain & sprocket drive,
close by the smaller sprocket
wheel in order to enlarge its
contact-arc, therefore contact
application from the outer side of
drive. In mounted position, the10si1r-arm should stay close to parallel to the chain & sprocket run, in drain direction. By extremely long chain & sprocket drives it is recommendable to install several10si1rs or the type “Boomerang®” in order to enlarge the slack compensation. Reversible Chain & Sprocket Drive:By reversible chain & sprocket transmissions, it is recommendable to install a10si1r on each side of
the chain & sprocket-strands. Due to the
alternate occurring of the
slack, both10si1rs should
only be pre-tensi1d up to
max. 20°, in order to retain a
reset-path of 10°, when strains are changing from slack span on working span in reversible applications.
Sprocket Teeth in Mesh:By the initial10sioning of the chain & sprocket, at least 3 teeth of the10si1r sprocket wheel should be in mesh with the rollers. The min. distance between the sprocket wheel of the10si1r to the next sprocket wheel in the chain & sprocket drive should be at least 4 chain & sprocket-pitches.Adjustment of Chain & Sprocket Track:The wheel of the sprocket wheelset is adjustable according to the position of the chain & sprocket drive track. The wheel is positi1d between 2 nuts on the threaded shaft. In changing the adjustment band “R”, the track of the10si1r wheel can be set according to the relevant strand course. After positioning the sprocket, re-tighten the 2 nuts on the side. The counter-nut “B” remains always tightened.
