Oil seals are used for automobile engines and geared motors, and are designed mainly to prevent oil leakage from the end of a rotating shaft, or dust intrusion from the outside air.

Oil seals serve to prevent the leakage not only of lubricants, but also water, chemicals, and gas from “gaps” in machinery. Oil seals also serve to prevent the intrusion of dust, soil and sand from the outside air.

Oil seals are indispensable sealing devices and are used in various fields, including automobiles, aircraft, boats and ships, railroad vehicles, construction machinery, farm machinery, petrochemical plants, and electrical home appliances.

Japan’s history of oil seals is, in effect, NOK’s history of oil seals. NOK has always produced stable, high-quality products based on its unique principle of sealing.

Packings are used as sealing devices for hydraulic and pneumatic cylinders used in various machines. NOK provides a wide range of packings for many purposes, including those for pistons, piston rods, etc.

“Packing” is a collective term for sealing devices that are mounted on the moving parts of hydraulic, pneumatic, and water-pressure equipment. Packings are used for industrial equipment such as hydraulic cylinders, power shovels, bulldozers, industrial robots, and hydraulic elevators.

NOK continues to develop ideal packings that improve the reliability of industrial equipment. Examples include NOK Noxlan packings (Noxlan is a brand name for NOK polyurethane rubber, used exclusively for packings), the performance of which far exceeds the maximum limits of conventional packings.

O-rings are O-shaped ring packings, and are used to seal fluids and dust. NOK has a broad lineup of rubber materials that can meet various service conditions.

O-rings are ring packings with an O-shaped cross-section. O-rings are placed in groove portions and pressed in moderately before being used to prevent leakage of fluids, such as oil, water, air, gas, and others.

NOK uses synthetic rubbers for many purposes, including the manufacturing of O-rings that can withstand prolonged use in harsh environments.
