Bearing arrangements that do not require maintenance lend themselves to application in the lift masts of wheel loaders. All bearings coated with ELGOGLIDE® are especially suitable in this case. This sliding layer, which is based on a Teflon® fabric, makes INA brand bearings absolutely maintenance-free. They require no additional lubricant supply. The PTFE in the sliding layer ensures functional reliability and enables maintenance-free operation for the life of the part. Oscillating motion such as the frequent swiveling motion present in construction equipment is ensured. This is due to the solid and moisture-resistant combination of the sliding layer with the steel support body. Overall, the customer receives a bearing solution that's impressive due to its well-balanced combination of high load carrying capacity, excellent wear and frictional behavior as well as outstanding dry running characteristics.
