Heavy Duty 89mm Diameter Flat Return Idler Belt Conveyor C3 Clearance
Heavy Duty Conveyor Flat Return Roller Idler for Belt Conveyor
Flat Return Idler automatically prevents the belt from misalignment and protect the belt edges from damages.
The return idlers is used to carry the the empty belt in the return side or the lower side of the conveyor belt.
Self-Training Flat Return Idler automatically prevents the belt from misalignment and protect the belt edges from damages. The self-training flat return idler is used to adjust the misalignment on the return side.
flat return roller suspended frames are commonly used on underground conveyor structure for ease of removal. These are designed to suit the customers specific loading requirements, and are available in high quality hot-dip galvanised steel as standard.
Housing is completed through sequential punching on imported superior steel sheet(SPCC), Finished housing features even thickness, good surface, precise measurement and consistency. Inner radius of housing completed is in conformity with designed value and roughness required by bearing and tube. The surface of housing is phosphated and degreased to improve cohesion of painting film.
selects labyrinth sealing arrangement which consists of two non-contact seals(inner seal and outer seal)and is waterproof with low rotation drag. All seals are made from PA/ABS. uses top lithium-based grease to fill in seals.
roller bearing uses double seal (ZZ) deep groove ball bearing with C3 clearance. Volume of lithium based grease filled inside ranges from 1/2 to 2/3, which secures the long service life.(Note: In view of visibility, the bearing on right graph omitted).
