114-0711 150 mm OD Bearing Ring
Cat® 150 mm OD Plastic Backup Ring for Hydraulic Cylinder Seals
Description
The backup ring is used to hold elastomeric or plastic seals in the desired shape and correct position. Using a backup ring allows an O-ring to be used in high-pressure applications that require a large extrusion gap and involve reciprocating or rotary motion.
Attributes
- Built to exact specifications for durability and reliability
- Distributes load more evenly across the seal, reducing stress
Applications
Backup rings act as a mechanical barrier in hydraulic cylinders, supporting and reinforcing seals and preventing the seals from being forced into the gaps between cylinder components.
