Groove Patterns
GMP Friction Products develops grooving and friction material to meet the unique needs of each application. The specific grooving pattern for a product is based on the oil flow needed for optimum performance.
Our wide range of integrally molded groove patterns allows our parts to provide high energy, low wear, unparalleled durability, and competitive friction levels compared to other materials. Our engineering staff will work with you to help you decide the best pattern for your project.
Spiradial - This grooving pattern may be used in wet (with oil) applications in which there is limited oil available due to the design of the brake or clutch.
Differential - Also known as the “sunburst” pattern, this relatively common grooving design is generally suitable for ordinary applications in which sufficient oil is available.
Spiral - Spiral grooving patterns are normally used in sump-type applications, in which the part is partially submersed in oil.
Radial - Radial grooving may be used in either wet or dry applications, depending on the specific design requirements.
Inside-Outside-Slot-Spiral (IOSS) - This complex, high-energy grooving pattern can meet the demands of severe applications in which there is very little oil or only a spray of oil available.
Plain - The plain lining, with no grooving, can be used for dry brakes or clutches.
