The cross-head is cast of crucible steel and faced with Babbitt. […] The rod is secured to the crank pin by body bound bolts, this bearing being provided with Babbitt shells which are prevented from turning by paper liners extending to the pin.

The most common bearing materials are Babbitts, both tin-base (as 89% Sn, 8% Pb, 3% Cu) and lead-base (as 75% Pb, 15% Sb, 10% Sn), and copper alloys, primarily copper lead, leaded bronze, tin bronze, and aluminium bronze. […] The Babbitts are unexcelled in conformability and embeddability, but they have relatively low compressive and fatigue strength, particularly above about 77°C (170°F). Babbitts can seldom be used above about 121°C (250°F).
