Wing roller is a side roller of Variable Angle Troughing Sets (Adjustable Troughing Sets), the roller shaft end have centre hole, it is easy and quickly to adjust the angle from 20 – 60°。Joyroll wing roller is designed to seamlessly interchange with many mobile crusher and screening equipment manufacturers original conveyor components。
Pipe:
◉ High precision longitudinal seam-welded steel pipe, materials S235JR(EN 10025-2),St37-2 (DIN 17100)
◉ Remove internal and external welding bars and uniform wall thickness ensure the roller good dynamic balance
◉ Good out of roundness of pipe ensure the roller have small T.I.R
◉ The pipe is cut and machined using automatic CNC machines, that guarantee the tolerances precision
◉ Roller surface treatment is electrostatic powder coating, thickness of coating approx. 80-120 μ.
Shaft:
◉ Cold-drawn round steel bar, materials S235JR(EN 10025-2),St37-2 (DIN 17100)
◉ High precision diameter tolerance, seat IT6 acc. to EN ISO 286-1, perfect match with bearings.
◉ Cut and machined by automatic numerically controlled machines
◉ Precise positioning of circlip groove ensure roller have very small axial movement.
◉ Galvanized shaft are available.
Bearing House:
◉ Made of high quality cold-rolled steel plate, materials DC01(EN 10130), St12(DIN 1623)
◉ High precision, smooth and no burr, bearing fit tolerance standard ISO M7
◉ Perfect concentricity ensure the roller low T.I.R
Bearings:
◉ Deep-groove ball bearings, tolerance class P5 (DIN 620)
◉ C4 radial clearance provides for optimum roller operation
◉ Bearings are filled with lithium base grease throughout its service life
◉ Nylon cage advantage: self-lubricating, abrasion resistance and low heat by friction, low noise, long service life
◉ A variety of brands are available (HRB,ZWZ,LYC,SKF,FAG,TIMKEN,NSK,NTN etc.)
Labyrinth Seal System:
◉ The system comprises of inner seal, labyrinth seal, galvanized metal dust cover, protective cover
◉ Inner lip seal prevent the pipe internal rusting entering the bearing, material is Nylon.
◉ Labyrinth seal have two parts, female labyrinth seal and male labyrinth seal, both material are Nylon or POM, especially effective against the intrusion of outside contaminants
◉ Labyrinth seal filled with lithium lubricating grease, maintenance-free throughout its service life
◉ The labyrinth system can be fitted with a rubber friction ring to prevent the intrusion of water
