Forged from high-carbon chromium bearing steel and treated with quenching and tempering, it boasts high hardness and toughness, capable of withstanding high-frequency axial thrust from the gearbox, resisting fatigue, and minimizing deformation and cracking. Precision grinding and mirror polishing of the end faces ensure precise control of flatness and parallelism, resulting in a low coefficient of friction, excellent heat dissipation, reduced wear on bearing and gear end faces, and extended gearbox overhaul intervals. Strict thickness and bore diameter tolerances, combined with a dedicated locking structure, effectively limit axial movement of the bearing, ensuring gear meshing accuracy, reducing transmission noise, and improving shifting smoothness. Designed for heavy-duty, high-load operating conditions in heavy trucks, it is resistant to high and low temperatures and aging, maintaining stable performance within a temperature range of -40\u2103 to 120\u2103, making it suitable for harsh road conditions such as construction waste, long-distance travel, and mountainous areas.<\/p>","protected":false},"featured_media":5867,"template":"","meta":{"_seopress_robots_primary_cat":"","_seopress_titles_title":"WG2229020025 Thrust Bearing Washer | Truck Transmission Input Shaft Spacer","_seopress_titles_desc":"WG2229020025 thrust bearing retaining washer is a key transmission component for heavy-duty trucks.
