OEM Design Customizable 89mm Dt Ii Idler Roller

Guarante Half A Year Customizable Black Dia 89mm DT II Conveyor Roller

DT II A standard Pulley

Using international standard design and manufacturing technology,the corporation can produce head pulley,tail pulley,and bend pulley.
Driving Pulley is the main part for transform the power.As per the different carrying capacities,the driving pulley can be divided into three categories:light duty,medium duty and heavy duty.And for the same diameter of the pulley,there are many different axle diameters and central spans.

DT II Conveyor Roller

Light duty:

Bearing Aperture:80-100mm
The axle and the hub are connected by the single key.And its single plate welding.The axle is uni direct out.

Medium duty:

Bearing Aperture:120mm-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 driving 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 anti-slippery and drainage ability,but is has its own direction.The rhombic lagging is available for two-way operation conveyors.The vulcanized rubber lagged pulley are mostly used for important application.
The bearing housing of the pulley is lubricated by grease cup style lubrication.

Centering Idler DTII Groove

Idler is an important part of belt conveyor, which has many kinds and large quantity. It accounts for 35% of the total cost of a belt conveyor and bears more than 70% of the resistance, so the quality of the idler is particularly important.

The role of idler is to support the weight of conveyor belt and material. The operation of idler must be flexible and reliable. Reducing the friction between conveyor belt and idler plays a key role in the service life of conveyor belt which accounts for more than 25% of the total cost of conveyor. Although the idler is a small part in the belt conveyor and its structure is not complex, it is not easy to make high quality idler.

There are several criteria to judge whether the idler is good or bad: the radial runout of the idler; the flexibility of the idler; the axial displacement.

Characteristics of parallel idler

The parallel idler has very high wear resistance, very low friction coefficient, and is not easy to wear the belt; it has excellent self-lubricating property, no need to inject oil, and is not easy to be stuck when it is used under bad conditions; it has anti-static, anti combustion, anti-aging, acid, alkali and organic solvent corrosion resistance; it can withstand repeated impact and vibration; the service temperature range is - 40 ℃ -90 ℃; excellent mechanical properties, light weight, easy installation, no maintenance; stable operation, long life and other characteristics.
