Erw Steel Belt Return Roller For Industrial Conveyors

Our company adopts special fine welding steel pipe for Roller, and does puncture processing in the tube. The roundness is controlled in special tolerance scope. The axle is according to standard tolerance and manufactured by fine cold drag steel. The bearing housing has been manufactured after stamping many times by the cold griped steel. The Roller shell and bearing housing have been welded together by the automatic welding machinery hand. Then it forms a whole high strength structure. The bearing, which uses the world famous brand, is the big roving crack, deep groove ball and double sealing bearing. It makes the Roller has the ideal static and dynamic balance that is better than the national standard. The above technical conditions can guarantee the Roller enjoy 10000-15000 hours of working life. At present, the Roller series products include the carrying Roller, the return Roller, the impact Roller, the training Roller, the spiral Roller, the Roller with rubber rings, etc.

Product characteristics:

Specifications:

ROLLER BODY : The shell is made of precision smooth Surface a ERWa Steel tube as per IS : 9295.
ROLLER ENDS : Bearing housing made of pressed steel sheet with calibrated bearing seat, are welded with the periphery of the steel tube, for maximum strength.
SPINDLE : Spindless are made from MS bright bars and are precision ground at bearing and seal seating areas.
BEARING: Precision single- raw deep groove ball bearing with C3 clearance are provided. Distance between bearings and point of support at the shaft is very short and thus ensure higher load carrying capacity and longer service life.
SEALING : The double multi labyrinth seal ensure optimum protection against the entry of dust and dirt in to the bearings.
INNER SEAL : RAIN CAP.
LUBRICATION : Hi-lithium base-greases is filled in measured quantities in bearing and seals, and rollers are sealed for life.
ADJUSTABILITY : Idler rollers are manufactures as per IS 8598 for belt with as per IS 4776 as well as to suit existing conveyor frame by providing adapter.
