CAT312 Excavator Carrier Roller | OEM Part # 4I7345, V990178V
Product Overview
Genuine OEM carrier roller engineered specifically for CAT312 excavators. This critical undercarriage component is designed to support the upper track chain, maintain proper track tension, and distribute the machine's weight evenly during operation. Replace worn or damaged rollers with factory-spec parts to prevent costly track misalignment, reduce fuel consumption, and extend the lifespan of your excavator's undercarriage.
Key Features
OEM Precision: Manufactured to exact CAT specifications (Part # 4I7345, V990178V) for perfect fit and compatibility
Heavy-Duty Construction: High-grade steel housing with heat-treated axle and sealed bearings for maximum resistance to impact, corrosion, and debris
Advanced Sealing System: Double-labyrinth seals prevent water, dirt, and contaminants from entering the roller assembly, reducing maintenance needs and extending service life
Optimized Load Distribution: Precision-engineered to support heavy loads while minimizing track wear and vibration
Direct Replacement: No modifications required - bolt-on installation matches original equipment dimensions and mounting points
Compatibility
This carrier roller fits the following CAT excavator models:
CAT312
CAT312B
CAT312BL
CAT312C
CAT312CL
Note: Always verify your machine's serial number and part number before purchase to ensure correct fitment. Contact our support team with your VIN for personalized assistance.
Why Choose Genuine OEM Parts?
Aftermarket carrier rollers may seem like a cost-effective alternative, but they often lack the quality control and engineering of genuine CAT components. Non-OEM parts can:
Fail prematurely due to inferior materials and manufacturing processes
Cause uneven track wear, leading to costly chain and sprocket replacements
Create excessive vibration, increasing stress on the excavator's frame and hydraulic system
