Long-Distance Conveyor Parts Flat Belt Conveyor Return Idler Roller

The role of the roller is to support the weight of the conveyor belt and the material, and is an important component of the belt conveyor.
Return rollers are often used in the return section of belt conveyors, that is, below.

Mainly used to support belts.

Due to factors such as conveying materials and working environment, the surface of the conveyor belt in the return section will often run with materials, which will cause the conveyor to fail to operate normally for a long time. The return cleaning roller-wire spiral and the return cleaning roller-comb roller are in On the basis of the ordinary return roller, iron wire or hot vulcanized rubber ring is welded on the surface of the roller barrel to clean the residual material on the belt surface.Among them, the return cleaning roller-comb type roller is widely used

The main performance parameters of the roller:

(1) Running resistance coefficient ≤0.03

(2) Outer circle radial runout≤0.7D (roller diameter)

(3) Water inflow ≤5g (water spray test according to national standards)

(4) Steel pipe wall thickness: when the roller diameter is 159mm and the bearing is 6308, the steel pipe wall thickness is not less than 4.5mm; when the roller diameter is 194mm and the bearing is 6308, the steel pipe wall thickness is not less than 6.3mm

(5) Bearing seat wall thickness: When the roller diameter is 159mm and the bearing is 6308, the bearing seat wall thickness is not less than 4mm; when the roller diameter is 194mm and the bearing is 6308, the bearing seat wall thickness is not less than 5mm

(6) Axial bearing capacity of roller ≥20000N

(7) Axial displacement ≤0.1mm
