Drum Pulley

Using international standard design and manufacturing technology, our factory can product head pulley, tail pueely and bend pulley.

Head pulley is the main part for transmitting the power. As per the different carring capacities, the head pulley can be divided into three categories: light duty, medium duty and heavy duty. and for the smae diameter of the pulley, there are many different axle diameters and central spans.

Lingt duty:

Bearing Aperture: 80-100mm

The axle and the hub are connected by the single key. And it's single plate welding.The axle is unidirectional out.

Medium Duty:

Bearing Aperture: 120-180mm

The axle and the hub are connected by the ring lock.

Heavy Duty:

Bearing Aperture: 200-220mm

The axle and the hub are connected by the ring lock. The shell body is aluminothermic welding fabric. The axle can be unidirectional and two-way out.

The surface treatment of the head pulley can be smooth steel, herringbone or rhombic rubber lagging. The smooth steel pulley is available for the place which environment is small power, small belt width and dry. The herringbone rubber lagging has a big friction factor, better anty-slippery and drainage ability, but it has its own direction. The rhombic rubber lagging is available for two-way operationg conveyors. The vulcanized rubber lagged pulley are mostly used for important applications.

The bearing housing of the pulley is lubricated by grease cup style lubrication.
