Carrying Rollers

close tolerances and longitudinally welded carrying roller tubes made of S235JR steel in accordance with DIN 2458; deep drawn steel bearing retainers with calibrated bearing seats pressed in from the side and circularly welded, material thickness min. s = 2.00 mm; RAL 3000 red powder coated sheath, coating thickness min. 60 U; 20 mm Ø round steel in accordance with ISO h9; single row radial steel ball bearings in accordance with DIN625 type 6204 with suitable grease filling and cover plates on both sides made of sheet steel C3 bearing clearance. The calculated service life of the ball bearings, assuming belt speed 2m/sec. delivery capacity 200 t/he bulk weight 0.75 t/m³ temperature range 0° C 50° C is 30,000 hours. Steel circlip in accordance with DIN 471 Sealing using double labyrinth seal, incl. suitable grease filling, galvanized, sheet steel sealing cap and plastic rain cap

The carrying frame prevents belt misalignment and guarantees protection of the belt edges. As the carrying frames only function efficiently when the drum casing is clean, they are equipped and delivered with dirt repellent 60° shore soft rubber. Our carrying frames can be used with both normal and reversing conveyor belts. Mode of operation When the conveyor belt is running straight, the axle through the roller casing forms an angle of 90° to the direction of movement of the belt. When the belt drifts, the roller casing moves, due to the dead weight of the belt, so that a forward motion occurs which brings the belt back to its normal position. The roller casing returns to its normal position as soon as the corrective procedure is completed. The mechanics of the movement are rendered possible due to a complex ball joint in the centre of the roller as well as the position of the axle in relation to the conveyor belt being less than 90°.

For the special requirements of your belt conveyor system, we manufacture for you idler pulleys, carrying idlers, throbbing drums, lift pulleys with or without internally located cone. With diameters up to max. 1,000 mm and lengths up to max. 4,500 mm, these are suitable for all types of belt conveyor system. All pulleys are turned cylindrically or spherically. The axle connections can be delivered in alternative designs with internal bearings, welded, with wedged connections or with clamping set shaft connections. Special designs such as stainless steel and/or friction linings (ceramic, rubber) and accessories (pedestal bearings) can be delivered upon request.
