Belt Conveyor Idlers & Pulleys


Rupraj Technical Services is one of the leading supplier of various types of bilk and package handling conveyors and systems and their components like idlers, rollers, pulleys, etc.

We have designed and supplied idlers in different Troughing Angles and for various usages for a wide range of Belt Conveyors. Impact, self aligning, Rubber lined, pvc lined, polymer, TEFLON, Rollers.


We are pleased to introduce non metallic , polymer conveyor rollers suitable for corrosive and adverse applications. These rollers are made from High Density Polyethylene. The versatility of this material enables us to satisfy a varied range of uses where other plastic and metallic rollers have failed.


These rollers have following advantages :
  • High wear & Chemical resistant
  • Belt Protection : When steel rollers fail they can produce sharp rotating edges, which can cut and rip conveyor belts at a very significant cost, causing unplanned down time and interruption to coal supply. In turn, cut conveyor belt traveling at high speed can pose a significant risk to employees working in the vicinity of the operating plant
  • Less Noise and Antistatic : The anti-static agent in this compound prevents sparking during operation in Volatile conditions.Such sought after feature when considering usage such underground mining where gas build–up can occur, also dusty conditions in grain storage areas
  • Light Weight : 50 % Lighter than steel shell rollers

1. ROLLER BODY : The shell is made of precision smooth surface ‘ERW’ steel tube as per IS : 9295 / IS 1239.

2. ROLLERS END : Bearing housing made of press steel sheet with calibrated bearing seat, are welded with the periphery of the steel tube, for maximum strength.

3. SPINDLE : Spindles are made from M.S. bright bars and are precision grou8nr at bearing and seal seating areas.

4. BEARING : Precision single-row deep groove ball bearings with C3 clearance are provided. Distance between bearings and point of support at the shaft is very short and thus ensure higher load carrying capacity and longer service life.

5. SEALING : The double multi labyrinth seal ensures optimum protection against the entry of dust and dirt in to the bearings.

6. INNER SEAL

7. DUST COVER

8. RAIN CAP

Rollers are manufactured as per IS 8295 standards

Rollers can be manufactured as per your design & specifications


Belt Conveyor Drums / Pulleys

Standard Conveyor Pulleys are favricated from steel shells / plates with welded end plates and bosses keyed / fitted direct / through Taper sleeve on the shaft.

Shell thickness before matching = from 8 to 20mm. The distance over bosses can be made to suit any requirement, however, we recommend that this be as wide as possible to keep the dimension between the boss and bearing to minium to reduce shaft flexing.

Drive / Tail / Take-up pulleys have machined crowned faces to train and reduce wear on Belt. Other pulleys are with straight face.

Plain or grooved rubber lagging can be furnished when additional friction is required between belt and pulley or if the application calls for the same such as handling wet / abrasive materials etc.

All Pulleys are concentric and statically baalanced and confirm to IS:8531.
