The Importance of Proper Bearing Assembly in Conveyor Pulleys

assemblyConveyor systems are unrecognized heroes. The long belts work all day and all through the night to move packages in mailing warehouses. They keep suitcases in line at international warehouses and work in the shadows to seamlessly drive everyday commodities from one place to another. In other words, they typically work behind the scenes, but this scenario reverses itself when we move to an industrial stage. In here the system is a central part of a long process, one that requires smooth operation at all times. Conveyor pulleys are responsible for this fluid movement. They form the backbone of the equipment, and the bearings that support these key components must be assembled properly.

The Important Role of Rollers

If this underlying mechanical rolling support is hampered in any way, then the belt is affected. Imagine a conveyor belt laden with mined gold or diamonds. The passage of the belt is a necessarily important part of the work, as any interference will cause the flow to stutter or entirely fail. The jerk of the belt could cause loss of valuable ore, and the cessation of the machinery will freeze a very profit-dependent operation in its tracks. Seals must be fully dust-proof and waterproof in this scenario because a contaminant in a mine or quarry will inexorably seek its way into the bearing assembly, thus compromising the operation of the equipment. The chain of equipment and amount of conveyor pulleys may stretch for a kilometre or more, but this expensive moving train can quickly be humbled by one malfunctioning bearing, a part that’s failed due to a small cloud of dust.

Addressing Angular Displacement Issues

There are always maintenance crews and repair teams floating around a working facility, but proper assembly allows these hard-working individuals to run off to other jobs. The bearings have to be tightened properly, of course, and this one action stops alignment from drifting. All conveyor pulleys demand angular alignment, even the pulleys that curve in wide sweeps around a corner. The pulleys work at a perpendicular angle to the belt, and this ensures level wear is absorbed by the drum and its cladding. If that alignment should be off or the pulley is so loose that alignment is lost over time, then wear is uneven, resulting in an off balance flow of conveyed material.

Linear flow is naturally improved when the pulleys of the conveyor are properly assembled, which in turn increases lifespan and lowers service costs.
