What Are the Best Caterpillar 307 308 E70B Carrier Roller Replacement Parts?

When replacing carrier rollers for Caterpillar 307, 308, and E70B excavators, the best options are those that offer precision engineering, high durability, and compatibility with OEM specifications. AFT Parts provides reliable, aftermarket carrier rollers that ensure seamless operation, increased longevity, and exceptional performance even in demanding conditions.

How Do Caterpillar 307 308 E70B Carrier Rollers Function in Excavators?

Carrier rollers, or top rollers, are essential for supporting the upper part of an excavator's track. They help prevent track sagging, maintaining correct alignment during operation. By reducing track tension and ensuring smooth movement across tough terrain, they contribute significantly to the efficiency and longevity of the undercarriage.

These rollers are placed centrally in the undercarriage, subjected to high load and wear, making regular maintenance and replacement necessary for optimal machinery function.

What Are the Common Signs That Caterpillar Carrier Rollers Need Replacement?

Carrier rollers that need replacement typically exhibit signs like uneven track wear, strange noises such as grinding or knocking, visible surface damage, or reduced performance in maintaining track tension. Increased vibrations or jerky movements of the track are also indicators that the rollers may need attention.

Prompt detection of these issues can prevent further damage to the undercarriage and reduce costly repairs.

Which Replacement Parts Are Compatible with Caterpillar 307, 308, and E70B Carrier Rollers?

To maintain optimal machine performance, it's important to select replacement parts that meet OEM specifications. Caterpillar 307, 308, and E70B excavators use compatible carrier rollers with part numbers like 333-5602, BA4300200, and 277-8576.

AFT Parts offers aftermarket carrier rollers that are designed to match these OEM specifications, ensuring the same durability and performance, but at a more competitive price.
