Idlers & Pulleys

Idlers

MACMET offers idlers for trouble free conveyor operations. A wide range of 'sealed for life' type idlers, with either seize resistant or deep groove ball bearings, are supplied to suit specific requirements. Idler selection is guided by the type of material handled, belt speed and service requirement. Fixed bracket type (both in-line & staggered) and garland type idlers with roll diameters from 76.1 mm to 219.1 mm are manufactured by MACMET.

Idlers are made from ERW black tubes conforming to IS:9295. The bearing housings are made out of deep drawn quality steel sheets. The pressed steel bearing housings are simultaneously welded on both sides of the tube to form a mono block construction. The idler spindles are made from EN-8/C-40 materials and are precision machined.

Pulleys

MACMET pulleys are time tested drive components for all types of belt conveyor systems. They are robust and reliable with long service life. Basic pulley diameters are 200, 250, 315, 400, 500, 630, 800, 1000, 1250, 1400, 1600 & 2000 mm. The pulleys, unless otherwise agreed with the customer, are rolled and fabricated from low carbon steel plates with end welded to the shell. For specific requirements and applications, turbo diaphragm type cast steel end discs are also used. All pulley shafts are made from C-40/EN-8/EN-8D/EN-9 grade steel.

The pulley shaft is generally keyed with the hub. Macmet also manufactures pulleys with tapered locking assembly arrangement.
