Rotary shaft seals are of many types and generally consist of a exible rubber sealing element, the metal insert/case and energized with garter spring. The purpose of the sealing element is to stop the uid from leaking between the shaft and housing. The sealing lip may be molded or molded with

Rotary shaft seals – or, most commonly, oil seals - keep in position a lubricant and for all other oil seals profiles, please visit the web catalogue.

The type A shaft seal according to DIN3760 is the most commonly used oil seal for low pressure ra- dial sealing. The rubber covered housing provides good sealing capacity even with rough housing bores.

on a 4.000" shaft rotating at 60 RPM. The lead angle equals 0.0456 = 2' 44.1". A 2" shaft with the same advance (0.300" in 30 seconds at 60 RPM) has a lead angle of 0.0912 = 5' 28.3". For best seal performance, industry standards recommend that the lead

oil seals, or rotary shaft seals, are made up of: 1) a metal structure, the body of the seal, whose function is to guarantee the stability and the resistance of the oil seal; 2) an elastomer lip ( nbr, viton, epdm; etc .) available different profiles, including single lip, double lip (most sold items), and high pressure profile 3) an

Radial Shaft Seals, also known as lip seals, are used for sealing rotary elements. Common elastomers are FKM, ACM, HNBR, AEM, and NBR. The compounds typical durometer is 70 to 85. Radial Seal applications can be simple designs, high heat, single lip, or more technical designs. Either way leave it up to our engineers to solve the problem.
