To realize maximum life from the gears and reducers in your plant, pay attention to their metallurgies and the operating viscosities of their lubricants. By Neville Sachs, P.E. In a typical facility, gears are usually the most common method of transmitting power and changing shaft speeds. Vast numbers of equipment systems, from cooling towers to paper […]
As machine designs evolve and energy efficiency remains a priority, synthetic lubricants are providing reliability professionals with an improved return on investment. By Grant Gerke, Contributing Editor Synthetic lubricants are quietly finding new footing in manufacturing. Maintenance teams and reliability programs are learning more about how polyalphaolefins, glycols, and esters achieve better viscosity at higher […]
Temperature is critical to the performance and life expectancy of lubricants and the components they protect. By Ken Bannister, MEch Eng (UK), CMRP, MLE, Contributing Editor In the lubrication world, temperature presents an interesting paradox and irony. The paradox is that lubricants require heat to flow efficiently over and around surfaces, most commonly bearings. However, if the temperature gets […]
By Ken “Dr. Lube” Bannister Symptom We have experienced lubricant-injector failures in a number of our conveyor lubricators. We’ve used the same brand of high-temperature chain oil for the past five years without issue, except for the last drum. In that drum, we discovered coagulated “lumps” floating in the oil. The oil supplier is blaming our […]
