    Profile

    Replace old seals without disassembling components—these seals come split for easy installation. Also known as clipper seals, they retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip to prevent leaks; fasten the hook and eye closure to secure. Press-fit seals into the housing bore; they fit tight for installation without a cover plate.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    A slippery PTFE surface allows these seals to function at speeds at least 25% faster than other rotary shaft seals. Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. An O-ring secures the lips to prevent leaks, while sealing against the housing. Press-fit seals into the bore around the shaft.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    Also known as V-rings and flingers, these seals protect shaft bearings by blocking dust and other contaminants while retaining lubricant. They’re Buna-N for excellent resistance to oil and grease. To install, stretch the seal over your shaft and press it firmly against the faceplate. The Seal OD and Seal Width listed are the dimensions of the seal after it is installed.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F. Also known as V-rings and flingers, they protect shaft bearings by blocking dust and other contaminants while retaining lubricant. To install, stretch the seal over your shaft and press it firmly against the face plate.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
