Alemite 6598-B Wheel Bearing Packer Pump 3/4 to 6 Inch

Product Description

The ALEMITE 6598-B is a wheel bearing packer pump designed for grease lubrication of wheel bearings across a range of sizes from 0.75 inches to 6 inches. Built from a combination of steel, aluminum, and stainless steel, this pump forces grease uniformly through the bearing cage and rolling elements, ensuring consistent coverage without air pockets. It is used by fleet maintenance technicians, automotive service professionals, and heavy equipment mechanics who require reliable bearing preparation before installation. The multi-material construction balances durability and corrosion resistance for shop environments.

This bearing packer pump suits applications where manual bearing packing is required prior to installation on axle assemblies, trailer hubs, and similar rotating components. It accommodates a wide bearing size range, making it practical for light-duty automotive work as well as heavier trailer and equipment hubs. Technicians working in fleet shops, tire service centers, and general mechanical repair will find this tool applicable across common bearing sizes encountered in everyday service.
