Originally titled 'Boundary Lubricant Prevents Metal-to-Metal Contact '
Dillon’s HPG500 is a premium boundary lubricant that prevents metal-to-metal contact under high load and slow speed conditions for either high-end manual chucks or power chucks. This high-performance NLDI grade 2 lubricating grease has great mechanical stability, high load carrying capacity, and excellent water and moisture resistance, according to the company. It has a water washout rating of less than 3 percent, making it one of the most water resistant products available.
Plus, its formulation gives it outstanding rust and corrosion resistance, even in the presence of a synthetic and oil based coolant environment. This chuck lubricating grease handles high loads and provides long-term corrosion protection under the most hostile conditions.
The environmentally friendly formulation contains no heavy metals or other environmentally undesirable materials such as compounds containing antimony, barium, lead, chlorine, phenols or phosphorus. This lithium-free formula does not react negatively when contacting the water contained in water based coolants as opposed to lubricants with lithium that cause lithium build-up on the internal workings of the chuck.
An all-purpose industrial lubricant, HPG500 can be used in bearings, bushings, slides, pivots, tracks, and so on, all important engineering components of manual and power chucks. It is recommended wherever high lubricity, EP (extreme pressure) properties, mechanical stability, rust and corrosion protection, water washout protection, and good oxidation stability are required.
Essential for safe operation, and maintaining maximum gripping pressure of chucks, HPG500 is available in 14-oz tubes. It can be purchased by the tube, in cases of ten or 50 each. A greasing set, consisting of a grease gun, two tubes of grease and one grease adapter fitting, is also available. HPG500 is also safe to use in machine centers that require EPI grease.
