Product Description
Shaft is high precision cold steel, Tube is high frequency seam welding, Decrease diameter runout and To ensure the operation process uniform rotation.Bearing use for HRB,ZWZ,LYC, bearing seat and dust cup use for high quality steel pressing, Lubrication using disposable high efficiency and long lithium base, And the labyrinth seal structure, waterproof, dustproof performance is good.
Roller load coefficient according to CEMA standard selection; Roller bearing with choose according to DIN standard;
Conveyor roller advantages:
1.Small Radial runout,weighting roller is below 0.35mm
2.Small rotating resistant,the resistant coefficient is below 0.010
3.Under testing of 72-hours water poof,water inflow is zero.
4.Permanent lubrication,long service life(at least 30,000 hours)
Carrier conveyor rollers are used to support and shape the conveyor belt. Conveyor carrier rollers can be fitted to the load side of the belt in: trough, tracking and transition frames, or fitted to the return side of the belt.

Conveyor Roller IDLERS features:
1. We are in desiging conveyor rollers combines the requirements of high quality and labyrinth seal.
2.Roller Shell : consist of a selection steel tube,machined at either to strict tolerance.
3.Bearing house : Formed from strip deep pressed and calibrated to ISO M7.this tolerance allowing a perfect match between the bearing and the relevant parts on the sealing.
4. The roller shell and the two bearing housings are welded together in an way that forms a monolithic structure of exceptional strength. This method guarantees the maximum precision and the minimum out of balance forces in the rollers.
5. Seal :Triple Labyrinth Seal design is grease filled and offers an additional level of protection from contaminants impacting the bearing CEMA C, D and E Idlers have sealed for life ball bearings.
6.Wide range of working temperatures from 0º C to 100º C.
7.Final Testing: Dimension,surface, Radial circular runout,Rotational resistance,Axial load,Water immersion seal,Axial displacement,Drop test.
Conveyor Rollers Production Process:
Conveyor Roller Advantage:
- Triple Labyrinth Seal
- Sealed for life ball bearings
- Extremely low rolling resistance
- CEMA C & D standard product line
- Idler end welding
- Solid steel shaft
- gauge steel shell/cover
Impact Roller Idlers:
Impact rollers are used as carrying rollers instead of normal steel rollers at a loading point. On steel roller there are rubber rings assembled, side by side, to absorb the weight and impact of material falling onto the belt. At the same time impact rollers reduce the shock and vibration through the steel structure.

Rubber Disc Return Roller Idler
Disc Return Rollers are used where the material has the potential to collect on the surface of the rollers which could ultimately lead to premature failure. The Ring minimises material build up on the roller shell. To maximise longevity, routine cleaning should still be observed. Rings come in rubber as standard.
