Our Rotary Shaft Seals are used for keeping out dirt, dust, water or other particles, while retaining lubricant in rotary shaft equipment. It was developed as a means of protecting bearings of rotating shafts. The sealing effect is achieved by preloading the sealing lip with a garter spring making its internal diameter slightly smaller than the shaft diameter. The garter spring ensures constant force to the shaft, flattening the sealing edge to a defined width. Available in Single Lip (SC) or Double Lip (TC).
