Trade Information

1. Product Overview

The 708-2E-12152 cylindrical roller bearing is customized for travel motors of Komatsu D65 series bulldozers with fully OEM-matched dimensions, complete with separate inner ring, outer ring and rib assemblies. Installed inside travel reduction motors, it endures continuous high-strength radial impact loads during heavy bulldozing and climbing operations. Its high load and wear-resistant features greatly extend the service life of travel motors, acting as universal replacement parts for D65EX and D65PX models.

2. Material & Processing Advantages

Made of standard GCr15 high-carbon chromium bearing steel with multi-step quenching and tempering heat treatment, the rollers and raceways of inner & outer rings have uniform hardness and stable metallurgical structure for outstanding anti-fatigue and pitting wear resistance. The line-contact structure of cylindrical rollers provides large contact area, delivering much stronger radial load capacity than ball bearings of the same size. The detachable split rib design simplifies assembly, disassembly and maintenance. Mirror finish on raceways reduces running friction, accelerates heat dissipation during high-speed operation and avoids high-temperature seizure, perfectly adapting to long uninterrupted mining and construction site work.

3. Precision Grade Options

P0: Standard cost-effective grade with high cost performance, suitable for daily earthwork and regular maintenance replacement on construction sites
P6: Tighter machining tolerance reduces vibration and temperature rise during operation, ideal for long-hour continuous heavy bulldozing work in mines
P5: High-precision grade for complete travel motor overhaul and hydraulic transmission system performance upgrade, offering superior concentricity and running stability

4. Quality & Installation Instruction

Manufactured strictly according to original 708-2E-12152 drawing specifications, the full set includes inner ring, roller cage, outer ring and limit ribs, enabling direct on-site replacement without extra accessories. Every finished product passes full inspection on clearance, surface hardness, dimensional tolerance and appearance. Custom P0/P6/P5 precision grades are available for bulk orders. Clean the motor cavity during installation and fill sufficient lubricating grease to reduce wear and extend bearing service life.

5. Application Scenarios

Widely applied for travel motor repair of Komatsu D65EX/D65PX bulldozers, export wholesale of construction machinery spare parts, regular maintenance of infrastructure and mining engineering fleets, solving common failures such as bearing wear, abnormal noise, heat seizure, power attenuation and weak traveling of travel motors.
