SKF is making its high performance RSH seal design available on a larger range of SKF Explorer deep groove ball bearings. The tried and tested RSH seal uses a highly optimised dual-lip configuration to provide additional protection in demanding environments. For users, the result is bearings that last longer, especially in wet, contaminated or dusty operating conditions, and that need to be replaced less frequently.
A secondary lip on the seal withstands high pressure cleaning and offers increased resistance to the ingress of dust and other contaminants, while the seal’s internal geometry has been optimised for smooth running and improved grease retention. It has an operating temperature range of -40 to +100 °C and up to +120 °C for brief periods. Previously only available on bearings with an bore diameter of 25 mm or less, the RSH seal has now been further developed and tested for use in bearings up to 60 mm in bore diameter. Users can specify SKF Explorer deep groove ball bearings with the new RSH seal installed on one or both sides, depending on the requirements of the end application. The new bearing variants are already being introduced, and the full range will be available worldwide by July 2017.
