JB-OR1A-G270

The FANUC part number JB-OR1A-G270 is an O-ring engineered for essential sealing functions in mechanical assemblies. It is composed of either Nitrile (NBR) or FKM, providing robust chemical resistance against oil, grease, and coolant. This feature ensures longevity and reliability in environments exposed to varying lubricants and fluids.

This O-ring exhibits an inner diameter measuring 27.0 mm and a cross-section of 3.0 mm, making it well-suited for various dynamic and static sealing applications. It maintains a pressure rating of up to 10 bar, which highlights its capability to withstand significant internal pressures. The hardness of the material is rated at 70A, offering a balance of flexibility and strength.

Operating efficiently across temperatures from -30 to 100 degrees Celsius allows this O-ring to be versatile in a range of climatic conditions. Its typical applications include the sealing of robotic joint housings, specifically as a J2/J3 reducer seal. The mount location for this O-ring is typically found in the gearbox or joint cavity, ensuring a secure and effective seal in critical robotic mechanisms.
