9237948 Carrier Roller for Komatsu PC20

9237948 Carrier Roller for Komatsu PC20 | Heavy Duty Undercarriage Part

9237948 Carrier Roller is the official OEM top roller designed for Komatsu PC20 2-ton mini excavators. As a core upper track undercarriage component, it supports the upper track chain, prevents track sagging, vibration and derailment. Built heavy-duty for African harsh construction sites, orchards, greenhouses, indoor demolition and municipal narrow trenching projects, this PC20 top roller delivers stable performance and long service life in muddy, high-temperature and dusty working conditions.

Premium Dual Heat Treatment Technology

To meet high-intensity mini-excavator working demands, FAJX PARTS adopts double heat treatment craft for the 9237948 PC20 carrier roller shaft:

1. Standard mesh belt heat treatment ensures surface hardness reach HRC52-58 for excellent wear and impact resistance.

2. Secondary vacuum furnace constant temperature tempering at 400°C for 4 hours deepens the hardened layer, keeping the shaft core toughness at HRC32. The hard shell and tough core structure perfectly combines rigidity and toughness, greatly extending the roller service life.
