Volvo EC360 EC360B EC360BLC EC360C EC360D Excavator Track Roller Bottom Roller Lower Roller SA1081-04411 1081-04411 14263401 5209264 Undercarriage Track Roller Group Heavy Duty Replacement

Product Overview
The Track Roller — also called Bottom Roller or Lower Roller — is the load-bearing roller mounted under the track frame of the Volvo EC360 excavator. It carries the full machine weight, keeps the track chain aligned, and transfers the load evenly to the ground. A worn or seized track roller causes track misalignment, accelerated wear on the chain and sprocket, and expensive downtime on the jobsite. Our rollers are engineered for the Volvo EC360 undercarriage family, covering the EC360, EC360B and EC360BLC series for a direct, bolt-on replacement.

Key Features & Benefits

• Broad Compatibility: Fits Volvo EC360, EC360B and EC360BLC excavators (compatibility with EC360C / EC360D should be confirmed by machine serial number). Replaces OEM part numbers SA1081-04411 / 1081-04411 and cross references 14263401, 5209264.
• Single & Double Flange Options: Both Single Flange (SF) and Double Flange (DF) versions available to match the exact position on the track frame.
• Heavy-Duty Material: Made from high-strength forged alloy steel (35SiMn / 40Mn2), providing excellent structural integrity and fatigue resistance under constant heavy loading.
• Advanced Induction Hardening: The tread surface is hardened to HRC 50-56 with a hardening depth of 5-10mm, significantly reducing wear from abrasive rocks, sand and dirt.
• Reliable Sealing Technology: Equipped with professional-grade bi-metal bushings and heavy-duty floating seals to prevent grease leakage and keep mud and water out of the bearing area.
• Lifetime Lubrication: Factory-filled and sealed, maintenance-free for the normal service life of the roller.
• True OEM-Style Fit: Manufactured to original specifications, easy to install without modifying the track frame.

Why Trust Our Undercarriage Solutions?
For a 36-ton class excavator like the EC360, every track roller carries a significant share of the machine's total weight — a failed roller means track misalignment, extra wear on the entire undercarriage and expensive downtime. Every roller we produce is 100% inspected for hardness, dimensional accuracy and sealing quality before shipment. Our goal is to deliver genuine-compatible durability at a more competitive price, backed by a clear warranty. Contact us with your machine serial number, current part number and position (left/right, SF/DF) to confirm the correct fitment.
