SB13S

Spring-loaded Single-lip PTFE rotary shaft seal with wiper lip

The spring-loaded lip design allows the seal to accommodate low rpm shaft runout or coaxial misalignment up to 0.020″ and high surface speeds. The opposing lip facing the environment acts as a dust wiper for dirt exclusion and as a lubricant retainer.  It is capable of handling extreme temperature, aggressive media, higher surface speeds, low to medium pressures, and can even run dry. The soft seal OD eliminates damage to housings manufactured from expensive metals. An integrated O-ring on the OD of the seal serves as an anti-rotation device and provides positive static sealing between the seal and the bore. Small quantities are available in 2-4 days.
