| Neat Idea Enables Faster and Easier Grease PMs |
|
| Create a lube panel located in a convenient location on or near the machine so that hard-to-reach grease fittings can be centrally located using line extensions. This makes greasing the machine faster and more convenient for the operator or lubrication technician doing the preventive maintenance task. Remember, a PM that is made quick and easy is a PM that gets done!

Question: How much pressure can a grease gun generate?
|
GET THE ANSWER
| This article outlines a number of points to keep in mind when selecting lubricant for gears. Knowledge on a host of technical and performance attributes leads to better, more precise decisions. Consideration of synthetic lubricants should be included in that decision-making process. |
FULL STORY
From the book “Oil Analysis Basics – Second Edition” by Jim Fitch and Drew Troyer:
VI improvers are long-chain polymers of high molecular weight used to boost the viscosity index (VI) of lubricants that are routinely exposed to wide-ranging oil temperatures. An oil’s temperature, whether high or low, directly impacts its viscosity. Low temperatures increase viscosity, while high temperatures decrease viscosity. Both viscosity extremes (low and high) can degrade the quality of lubrication. VI improvers are used in oil formulations to reduce the rate of viscosity change as oil temperatures vary during service. VI improver molecules do this by shrinking (becoming smaller) as oil temperature drops and unfurling (becoming larger) as oil temperature rises. VI improvers consist primarily of polymers and esters such as olefin copolymer (OCP), polyacrylate, polymethacrylate ester (PMA) and polyisobutylene (PIB). VI improvers can be found in most engine oils, hydraulic fluids, automatic transmission fluids and gear lubricants.
