Dillon Chucks and Jaws’ HPG500 premium boundary lubricant is said to prevent metal-to-metal contact under high-load and slow-speed conditions. Suitable for the range of applications from high-end manual chucks to power chucks, this premium, high-performance NLDI Grade 2 lubricating grease is said to have exceptional mechanical stability, very high load carrying capacity and excellent water and moisture resistance. With a reported water washout rating of less than 3%, it is one of the most water-resistant products available. Additionally, Dillon says its unique formulation gives it outstanding rust and corrosion resistance, even in the presence of a synthetic and oil-based coolant.

According to Dillon, this chuck lubricating grease handles high loads and provides long-term corrosion protection under the most hostile conditions. Essential for the safe operation, and maintaining maximum gripping pressure of chucks, HPG500 is available in 14-ounce tubes. It can be purchased by the tube, in cases of 10 or 50 each. A greasing set, consisting of a grease gun, two tubes of grease and one grease adaptor fitting, is also available.

The lubricant’s formulation is said to be environmentally friendly, meaning there are no heavy metals or other environmentally undesirable materials or 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 which 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 more — all important engineering components of manual and power chucks. Dillon recommends the lubricant wherever high lubricity, extreme pressure (EP) properties, mechanical stability, rust and corrosion protection, water washout protection and good oxidation stability are required. HPG500 is also safe to use in machine centers that require EP grease.
