Product Description

SOLAR 300/DH280 Carrier Roller Replacement

OEM Part No. 2270-6126, V2270-6126V

Precision Engineered for Perfect Compatibility

Our carrier roller is manufactured to exact OEM specifications, ensuring a seamless fit for SOLAR 300 and DH280 excavators. Cross-referenced with part numbers 2270-6126 and V2270-6126V, this component eliminates the need for modifications during installation, reducing downtime and getting your equipment back to work faster.

Built to Withstand Extreme Operating Conditions

Constructed from high-tensile strength alloy steel, the roller surface undergoes a specialized heat treatment process to achieve a hardness rating of 50-52 HRC. This provides exceptional resistance to abrasion, impact, and corrosion, making it ideal for use in construction, mining, and forestry applications. Compared to standard aftermarket alternatives, our carrier roller offers up to 35% longer service life under heavy load conditions.

Advanced Sealing Technology for Long-Term Performance

Featuring a double-lipped nitrile rubber seal with a reinforced metal dust cover, our carrier roller effectively prevents contamination from dust, dirt, and moisture. Pre-lubricated with high-performance lithium complex grease, the internal bearings maintain smooth rotation and reduce friction, minimizing wear on critical components and eliminating the need for frequent re-lubrication.

Installation & Maintenance Guidelines

Installation Steps:

Park the excavator on a level surface and engage the parking brake
Use a jack to support the track frame and relieve tension from the carrier roller
Remove the mounting bolts and carefully lower the old roller from the track frame
Clean the mounting surface and inspect for any damage or wear
Position the new carrier roller and torque the mounting bolts to manufacturer specifications (refer to your equipment service manual)
Adjust track tension to recommended levels and test operation before returning to service

Maintenance Tips:

Inspect carrier rollers regularly for signs of wear, cracks, or seal damage
Keep the undercarriage clean to prevent abrasive debris from accelerating component wear
Monitor track tension periodically to ensure proper alignment with the carrier roller
Replace rollers immediately if excessive wear or damage is detected to prevent further damage to the track system
