E320 Excavator Top Roller For Excavator Undercarriage Parts, Improves Undercarriage Efficiency, Reduces Vibration And Impact

Product Overview

The E320 Top Roller, also known as carrier roller, is a vital undercarriage component specially engineered for CAT excavators. Installed on the upper frame, it reliably holds up the track chain to avoid track sagging, bouncing and deviation during operation. This premium roller effectively optimizes the overall running efficiency of the undercarriage system, while greatly cutting down vibration and impact force generated in working processes. Adopting superior raw materials and mature manufacturing techniques, it delivers stable performance, outstanding durability and long service life. It is an ideal OEM replacement part for various medium and heavy-duty construction, mining and earthmoving projects.

Compatible Models

This top roller is precisely manufactured to fit a wide range of CAT excavator models:

CAT E320
CAT E320B

Material & Manufacturing Proces

We select high-grade 50Mn / 40CrMn alloy structural steel as raw material. The roller body is made via integral forging, which strengthens structural rigidity and load-bearing capacity. The raceway surface is treated with high-frequency quenching, reaching a surface hardness of HRC 54–58 and a hardened layer depth of 6–9 mm. This process endows the roller with strong resistance against wear, impact and deformation.

Equipped with standard floating oil seal, paired with oil-proof, wear-resistant NBR sealing rings and dust-proof rings, the sealing system works perfectly to block mud, water and sand from entering the interior. The solid quenched and tempered shaft features excellent bending resistance, ensuring stable operation even under continuous heavy loads.

Product Advantage

Boost Undercarriage Efficiency: Supports track chain steadily to maintain normal track operation, effectively improving the overall working efficiency of the undercarriage.
Lower Vibration & Impact: Smooth rotation reduces mechanical vibration and impact force, relieving component fatigue and creating a more stable operating state.
Superior Wear Resistance: Forged body and deep quenched layer resist abrasion and heavy impact, not easy to crack or suffer eccentric wear.
Excellent Sealing Performance: Reliable floating seal prevents oil leakage and foreign matter intrusion, lowering the risk of early damage and reducing maintenance frequency.
Direct Installation: Strictly follows OEM standards, no modification needed for quick and easy replacement.
Wide Applicability: Performs excellently in earthwork, infrastructure, mining, gravel yards and other medium and heavy load working conditions.

FAQ

Q1: Which excavator models does this E320 top roller fit?

A1: It is fully compatible with CAT E320, E320B, E320C, E320D, E322 and E325 series excavators. All dimensions comply with OEM standards for direct installation.
