Trade Information

1. Product Overview

The 06030-23220 spherical roller bearing is developed for Komatsu D57S, D60A, D65A, D75S series bulldozers with fully OEM-matched dimensions. It is installed on frame supports and heavy-load travel supports. The unique self-aligning structure relieves shaft misalignment stress caused by bumpy bulldozing work and frame deformation. The high-strength solid cage avoids breakage and deformation, and withstands alternating impact loads in earthwork and mining sites. It supports cross-model replacement and acts as a cost-effective OEM substitute for routine maintenance and chassis overhaul of bulldozers.

2. Material & Processing Advantages

Made of standard GCr15 high-carbon chromium bearing steel with complete quenching and tempering heat treatment, the rollers and raceways of inner and outer rings have uniform hardness and stable metallurgical structure for excellent anti-fatigue and pitting wear resistance. The double-row self-aligning roller structure bears heavy radial pressure and bidirectional axial thrust simultaneously, tolerating minor shaft misalignment during assembly and operation. The integrated solid cage features good toughness and impact resistance to avoid breakage and deformation. The outer ring dust-proof groove prevents construction dust and mud ingress to avoid premature jamming and wear. The integral structure simplifies disassembly to cut equipment downtime and construction losses.

3. Precision Grade Options

P0: Standard cost-effective grade for regular earthwork and daily maintenance on ordinary construction sites
P6: Tighter machining tolerance reduces vibration and heat generation, ideal for long-hour heavy continuous bulldozing work in mines
P5: High-precision grade for complete machine overhaul and chassis travel system performance upgrade with superior concentricity and running stability

4. Quality & Installation Instruction

Manufactured strictly to original 06030-23220 specifications for direct replacement without secondary machining. Full inspection on clearance, surface hardness, sealing performance and appearance is carried out before delivery. Custom P0/P6/P5 precision grades are available for bulk orders. Utilize the bearing’s self-aligning performance to adapt to minor shaft misalignment during installation, fill sufficient lubricating grease and control uniform preload to extend bearing service life effectively.

5. Application Scenarios

Widely used for overhaul of Komatsu D57S-1, D60A-6, D60A-11, D65A-8, D75S-2 bulldozers, export wholesale of construction machinery spare parts and regular maintenance of infrastructure and mining engineering fleets, solving common defects of original bearings such as abnormal noise, jamming, uneven wear, excessive play, load capacity degradation and cage breakage.
