Manipulation of the grp stack is achieved through system calls such as setgid(), getgid(), and initgroups()

The sealing lip of the RST-D is more heavy-duty, so it can cope with pressures of up to 10 bar at slightly lower rotation speeds.
Oil seals require sufficient time to solidify and cure. Premature use of equipment with newly installed oil seals can compromise the integrity of the oil seal and may damage your machine. Refer to the supplied instructions for the time frame allocated for the seal to cure.

- 2. Material The material used to manufacture the 14x22x5 oil seal can vary depending on the application requirements. Common materials include nitrile rubber, fluoro rubber, and silicone rubber, each with its own unique properties such as temperature resistance, chemical resistance, and compression set.

HOW OIL SEALS WORK

Oil seals keep contaminants separate from the lubricants that keep rotating shafts and precision bearings in good working order. Oil seals are also known as rotary shaft seals, lip seals, and shaft seals.

Oil seals are widely used as sealing devices for machines.
JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.
Therefore, this series of columns will summarize the following in order:
• The structure, functions, and types of oil seals
• How to select the right oil seal
• Handling of seals, and causes and countermeasures for oil seal failure
