Northern Chain Specialties has the solution to conveyor chain roller wear, contamination, and lubrication problems: maintenance free sealed ball bearing wheel kits with a life cycle of 5 plus years.
These sealed for life rollers have a friction rating of less than 3 percent and are easily interchangeable with a wide verity of chains such as v-top, flattop, apron chain and can be custom designed to fit your chain. The low friction rate improves the life of the chain and the existing drives.
The sealed for life roller replace the standard needle bearings which create sidebar wear due to forced roller contact as the wheels rotate. Metal shavings from wear produce friction which may stop the wheels from turning. This, in turn, creates friction on the rail and increases load for the drive motor. The design of these rollers eliminates any premature sidebar wear due to the roller rubbing on its surface.
