Your source for Oil Seals
Oil seals are used to seal in lubricants and keep out contaminants. Also called rotary shaft seals or grease seals, they are used in axles, gearboxes, hydraulic cylinders, and many similar applications.
While sealing lubricants within the system and keeping contaminants out of the system, a well-fitted oil seal leaves a thin layer of lubricant on the shaft surface that lessens friction and optimizes mechanical performance.
In many applications, the oil seal is one part of the total sealing solution. Additional components like wipers, v-rings, and wear rings may be required.
