BR25 consists of multiple plies of heavy-weight canvas cloth saturated with phenolic resin system. The pre-preg (b-stage) plies are then laminated under heat and pressure to produce a thermoset composite material. The resin is modified with (1) graphitic carbon, which provides internal lubrication to reduce frictional heat generation and wear of metal shafts on the bearing, and (2) alumina, which adds hardness to the bearing to reduce wear. BR25 laminates offer load-bearing capacities equivalent to those of brass and bronze, but will not seize to metal shafts, speeding up bearing replacement and reducing equipment downtime. Compared to thermoplastics, BR25 provides superior load-bearing properties and has a Coefficient of Thermal Expansion that more closely matches the CTEs of metal shafts.

In addition, steel and aluminum rolling mills prefer BR25 bearings to metal and thermoplastic bearings because they last longer in many applications and can be replaced quickly during overhauls.
