The 06030-22311 spherical roller bearing is developed for Komatsu D41, D57S, D58, D60D, D70 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 solid brass cage boasts high strength to withstand 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.
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 brass 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. Split structure simplifies disassembly to cut equipment downtime and construction losses.
Manufactured strictly to original 06030-22311 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.
Widely used for overhaul of Komatsu D41-6, D57S-1, D58-1, D60D-8, D70-8 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.
