Polyurethane Double Lip Sealing Rings: Designed as contact seals, these sealing rings protect the bearing position against contamination, spray water and the excessive loss of grease. Sealing rings are matched to the small radial dimensions of needle roller bearings. They are very easy to fit, as they are simply pressed into the housing bore. Sealing rings allow circumferential speeds at the seal lip of up to 10 m/s depending on the surface quality of the shaft. This sealing ring features a contact lip and a non-contact dust shield lip facing the shaft. The seal carrier is made from reinforced polyamide (coloured black), while the seal lip area is made from thermoplastic PU elastomer (coloured green). Suitable for operating temperatures from -30 to +100 deg C. Note: Sealing rings SD have an oversized outside diameter. This gives firm seating once the rings are pressed into the housing bore. The rings will adopt their correct geometrical form once fitted in the bore.
Benefits: Easy to fit, protects against contamination, spray water and excessive loss of grease, highly wear-resistant and resistant to environmental influences and many mineral oils.
