C93700/SAE 64
- Typical Uses


Characteristics:
Good strength; low thermal conductivity compared to high-tin bronzes; generally high physical properties combined with fairly good bearings qualities; corrosion resistant to mild acids as found in mine water, good resistance to mineral waters or paper-mill sulfite liquor; excellent wear resistance under conditions of high speed, heavy pressure, shock and vibration; low friction; good machining and fair casting properties; can be used where lubrication is doubtful; requires hardened shaft, maximum shaft surface speed can be 800-1000 fpm.

Uses:
Heavy loads and high speeds; backings for Babbitt-lined bearings; wrist-pin and valve rocker arm bushings; fuel and water-pump bushings, aircraft control bushings, electic-motor bushings, steering knuckle bushings; track-roller bushings; crankshaft bearings for outboard motors, power lawn mowers and garden tractors; gear bushings for farm equipment, reducers and motorcycles; cam bushings for mechanical devices; farm equipment and diesel engines; piston pins for packaging equipment and diesel engines; linkage bushings for presses; roll-neck bearings, lathe bearings; Babbitt-lined armature bearings for electrical locomotives; railroad-car bearings; rolling-mill bearings; trunion bearings, impellers; pumps.
