ROULEAUX DE GUIDES À ANGLE FIXE

Rouleaux de guides, Le rouleau à ailettes latérales de Joyroll est conçu pour s’interchanger de manière transparente avec les composants de convoyeurs d’origine de nombreux fabricants de concasseurs mobiles et d’équipements de criblage. Les rouleaux d’aile latéraux peuvent être réglés à 20°, 30°, 45° ou 60°, d’autres angles peuvent également être disponibles.

◉  Side roller length B and its angle can be custom manufacturing,  please contact our sales engineer for specific requirements.

Fixed Angle Troughing Wing Roller Sets

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
