Logan Groove Pattern Descriptions and Friction Materials

Logan Groove Patterns

Logan groove patterns enable oil to be redirected for fast heat dissipation or contained to allow adequate lubrication in applications where only a mist or spray of oil is available.

Our wide offering of integrally molded groove patterns enable our materials to provide high energy and low wear. Consistent durability, and competitive friction coefficients are additional features when compared to other materials.


Grooving pattern that may be used in wet (with oil) applications where there is limited oil available due to the design of the brake or clutch



A relatively common pattern, also known as the "sunburst", is generally suitable for ordinary applications where which sufficient oil is available 



Normally used in sump-type applications where the part is partially submersed in oil



May be used in either wet or dry applications (depending on the specific design requirements)


Inside-Outside-Slot-Spiral (IOSS)

Complex, high-energy grooving pattern can meet the demands of severe applications where there is very little oil or only a spray of oil available



A plain lining, with no grooving, can be used for dry brakes or clutches

Logan Friction Materials

Metallic Friction

Our metallic friction materials are composed of a number of base metals. Copper, bronze, iron or iron-bronze bases conduct heat away from the part during use, allowing controlled motion.

Ceramic Friction

Our ceramic friction materials act as insulators, driving heat away from the friction material surface. They also offer low wear, for applications that demand long life and high durability.


Graphitic Friction

The graphite in our graphitic friction materials gives them high energy capacity and low wear, making them ideal for demanding applications.
