Info

Cover plate SC...ECCover plates are available for all SNC bearing housings. The cover plate is made of corrosion-resistant sheetsteel and has a circular rubber lip made of NBR (butadiene acrylonitrile rubber). It is fixed in the sealinggroove between the upper and lower section and effectively seals the housing. Cover plates can be combinedwith any other seal in the SNC range. The temperature range for cover plates is between -40°C and+100°C.For details of the dimensions of the permissible shaft ends, refer to the dimension table (dimension w 1 ).The delivery includes one cover plate with vulcanised rubber lip.Special sealsIn special cases, it is possible that standard seals will not satisfy specific operating requirements. For example,if particularly high temperatures are required, SNC bearing housings can be fitted with seals made ofspecial materials. SNR bearing housings can also be used in solutions that differ from the standard shape.SNR bearing housings can also be adapted with sealing solutions that differ from the standarddesign.16
