E330 Idlers – Heavy-Duty Undercarriage Rollers for 30-Ton Class Excavators

E330 idlers are engineered for 30-40 ton excavators, providing reliable track support in demanding earthmoving, quarrying, and construction applications. These components are crucial for maintaining proper track tension and alignment on machines like the Caterpillar 330, Komatsu PC300, and Hitachi ZX330.

Key Features

✔ Forged Steel Construction – Superior strength and impact resistance compared to cast idlers
✔ Sealed & Lubricated Bearings – Extended service life with minimal maintenance
✔ Precision Machined Surfaces – Smooth operation with reduced track shoe wear
✔ OEM-Compatible Design – Direct replacement for original equipment idlers

Types of E330 Idlers

1. Front Idlers (Guide Idlers)

   • Maintain track tension and alignment

   • Available in smooth or grooved designs

2. Bottom Rollers (Lower Rollers)

   • Support machine weight and track chain movement

   • Double-flange design for optimal load distribution

3. Carrier Rollers (Upper Rollers)

   • Prevent track sagging on upper frame section

   • Single or double flange configurations available

Performance Benefits

• 20% Longer Service Life compared to standard idlers

• Reduced Undercarriage Vibration for smoother operation

• Interchangeable with major OEM part numbers

Compatibility

Designed to fit:

• Caterpillar 330, 330B, 330C, 330D

• Komatsu PC300-6, PC300-7, PC300-8

• Hitachi ZX330, ZX330-3, ZX330-5

• Volvo EC330, EC340 EC360 

When to Replace E330 Idlers?

⚠ Visible flange wear exceeding 30% of original thickness
⚠ Flat spots or irregular wear patterns
⚠ Failed bearings causing roller seizure
⚠ Oil leaks from damaged seals

Maintenance Recommendations

• Clean Regularly – Remove packed mud and debris
• Check Every 500 Hours – Inspect for abnormal wear
• Replace in Sets – For balanced track performance

Pro Tip: For extreme conditions (mining, rock quarries), consider hardened or tungsten-carbide coated idlers for 2X longer lifespan.
