NOW ON ML Find more great articles and content from Machinery Lubrication magazine online. From Web exclusives and industry news to videos, white papers, buyer's guides and more, everything that relates to machinery lubrication is available now on When a bearing is making noise, internal damage has likely occurred. If the bearing continues to run without being replaced, more internal damage may occur with the potential for failure. Access this 1-minute, 7-second video at Troubleshooting Hydraulic Strainer Issues There could be several reasons for a downward trend or even a sudden drop in viscosity without warning. However, the most common cause is adding in a lower viscosity fluid than what's required. A decrease in viscosity may also occur when non-lubricants like solvents and diesel fuel accidently get into the lubricant. If this happens, it is a good idea to change the oil. Find this article on the ML site to learn other ways your lubricant could be losing its viscosity. Hydraulic systems undergo several pressures. Where a strainer is placed within the system will decide the pressure it will experience. Obviously, if the strainer is on the return side, it will endure less system pressure and may potentially last longer. Read this article on the ML site to discover what could cause a hydraulic strainer to blow out. Lubrication Myth: Add Grease to a Noisy Bearing This video explains why adding grease to a bearing that's making noise may only provide temporary relief. Instead, a noisy bearing should be closely monitored and replaced as quickly as possible. Why an Oil's Viscosity Drops Catastrophic Ball Bearing Failure This video shows a ball bearing failure of a power plant condensate pump. The pump is a vertical KSB unit from 1972 that is almost 20 feet tall. The bearing box has three ball bearings, and the uppermost has evaporated. The other two were cracked, burned, bent and heavily distorted. The shaft was distorted as well. Access this 55-second video at The Disadvantages of Using Anti-Friction Metal Conditioners Using "metal conditioners" generally is not recommended because most of these types of products are derived from a chlorinated compound. The chlorine in these compounds is very reactive with a metal surface and will immediately corrode it. Understand why it is better to have your equipment operating under a full hydrodynamic fluid film, as opposed to relying on a friction barrier under boundary conditions, by reading this article on the ML site. Featured White Papers is the place to turn for white papers on a host of lubrication-related topics. Here's a sampling of the latest white papers that are currently available for download: • • • • 42 | July - August 2013 | Alternatives to Traditional Oil Testing Using SEM/EDX Overview of FluidScan Handheld Infrared Oil Analyzer Find Sources of Energy Waste A Practical Guide to Shaft Alignment Check out the full list of white papers by visiting and clicking on the "White Papers" link.
