Up to 40 per cent of a vegetable crop can go to waste due to the aesthetic requirements of some supermarkets. While a wonky vegetable may not be the most visually pleasing, it possesses the same nutritional value as its perfectly proportioned counterpart. Here, Chris Johnson, managing director of bearing specialist SMB Bearings, explains why not all bearing surface damage should cause alarm and future headaches for offshore oil and gas plant managers.
Bearing surface damage can take many forms, from spalls in the raceways, wear from ineffective lubrication, corrosion due to harsh chemicals to false brinelling marks caused by static vibration. While surface distress can result in problematic symptoms such as excessive heat, increased noise levels, increased vibration or excessive shaft movement, not all external bearing flaws point to compromised internal machine performance.
