Return idlers support the conveyor belt on the unloaded branch. The catalogue includes straight return rollers, V-shaped and reverse-V arrangements, rubber-disc configurations, polyurethane-disc options, and steel return rollers.
The correct configuration depends on belt width, stiffness, material build-up, return-run tracking, and spacing between idler stations.
Rubber-disc return rollers help separate material from the belt and reduce build-up on the return strand. V and reverse-V arrangements can also help control belt deviation in suitable layouts.
| Model / Arrangement | Application and Configuration |
|---|---|
| Return A Type | Straight return roller; equal support-ring spacing; for light/stiff belts and shorter idler spacing |
| Return A(I) Type | V-shaped or reverse-V arrangement for wide/light belts; helps restrain belt deviation |
| Return A(II) Type | Support rings concentrated at both roller ends; tighter outer-belt support and smoother running |
| Return B Type | Tight flat support surface; for medium/heavy belts with longer idler spacing |
| Return B(II) Type | V-shaped or reverse-V support for heavy/wide belts; supports belt tracking on the return run |
| Return Steel Idler Roller | For clean, non-sticky belts; rubber lagging options of 5 or 10 mm are shown |
| Reference Family | Catalogue Coverage |
|---|---|
| Straight A / B Types | Tables include L values up to 2200 mm and B values up to 2000 mm |
| V / Reverse-V Types | Multiple L/B/D/P combinations for wide conveyor belts |
| Roller Diameters | 108, 133, 159 mm; selected configurations also show 219 mm |
| Support Ring Count | Varies by roller length and configuration; catalogue tables show multiple combinations |
| Disc Material Options | Rubber discs; polyurethane discs also stated as available |
The catalogue identifies A-type and B-type rubber disc systems and notes ISO, SMS, and SFS references. Tailor-made support-ring assemblies can be confirmed according to the conveyor application.
Please provide conveyor belt width, roller function, roller diameter, face length, shaft diameter and end style, bearing requirement, troughing angle, bracket arrangement, operating speed, material handled, load, environment, surface treatment, quantity, drawing, or sample. Final dimensions and compatibility are confirmed according to the order drawing.
