Ball bearings have new performance seal option

Ball bearings have new performance seal option

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 protec-tion in demanding envi-ronments. For users, the result is bearings that last longer, especially in wet, contaminated or dusty operating condit-ions, and that need to be replaced less fre-quently.

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.

The seal is made from acrylo-nitrile-butadiene rubber (NBR), which is resistant to mineral oil based lubricants, petroleum products and animal or vegetable fats. 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 25mm or less, the RSH seal has now been further developed and tested for use in bearings up to 60mm 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 extended RSH offering joins a growing list of options and improvements in the SKF Explorer range. These include numerous different shield and seal configurations and a choice of cage materials and lubricants.

The SKF Explorer offering has been continuously extended and improved for more than two decades, with deep groove ball bearings joining the range 15 years ago.
