173 Connecting Rod Bearing: The "Friction Buffer Barrier" of 173 Heavy Engines

The 173 Connecting Rod Bearing is the "friction buffer barrier" of 173 heavy engines, designed for wear reduction in heavy-load conditions. Its steel backing is high-strength cold-rolled steel, with thickness uniformity controlled within 0.01mm, evenly bearing crankshaft radial pressure to avoid deformation from local stress concentration.

The surface tin-lead-copper alloy wear layer has 20% copper content, 30% harder than ordinary tin-lead layers while retaining excellent friction reduction—avoiding "bearing burnout" even with short-term insufficient lubrication; the top antifriction coating further reduces initial operation friction, extending break-in life.

Old bearings often have "engine noise" and "power drop" due to wear layer peeling and excessive clearance. After replacing with the 173 Bearing, component friction loss decreases by 60%, engine operation smoothness increases by 40%, adapting to continuous high-load operation of heavy generators and pumps.

Whether for high-power construction equipment or farm heavy machinery, the 173 Connecting Rod Bearing buffers friction impact between crankshaft and rod with "high load-bearing + low wear + damage resistance" performance, being the core friction component for reliable operation of 173 heavy engines.
