Product Overview

561-15-79690 is a large bore deep groove ball bearing exclusively for Komatsu HD785-7 heavy mining dump truck transmission, listed as No.8 in transmission assembly breakdown list, 1 piece standard equipped per gearbox. Widened & thickened inner and outer ring matched with solid brass cage, evenly arranged steel balls deliver higher load limit and resist heat deformation during high-speed rotation. It bears both radial and bidirectional axial force, effectively buffer impact load caused by vehicle bumping during mine transportation, reduce abrasion of transmission housing, gears, pistons and other matching parts, extend overall overhaul cycle of dump truck transmission.

Material & Precision Manufacturing Technology

Inner ring, outer ring and rolling steel balls are all made of Gcr15 high carbon chromium bearing steel, processed by forging, precision grinding and integral quenching heat treatment for uniform stable surface hardness, superior wear and fatigue resistance compared with ordinary steel cage bearings. Integrated brass cage separates steel balls with excellent thermal conductivity, preventing seizure or crack during long-time continuous mining operation, outstanding dust & rust resistance for open-pit mines with heavy dust and wide temperature difference.

Optional Precision Grades

Customizable with three precision grades: P0 general industrial standard grade, P6 medium precision, P5 high precision. Standard stock is P0 grade with sufficient inventory and short lead time, bulk supply for overseas construction machinery spare parts wholesalers, repair shops and OEM refitting factories, meeting procurement demands of equipment renovation, original matching and emergency maintenance.
