It is engineered to deliver extended service life, reduce downtime, and protect your investment by ensuring smooth and reliable machine travel.
Key Features & Engineering Advantages
Precision OEM Interchangeability
Feature: Manufactured to the exact dimensions, load rating, and bolt pattern of the original SANY 13465919 component.
Benefit: Guarantees a perfect, hassle-free fit without any modifications, ensuring immediate restoration of machine performance and safety.
Enhanced Multi-Labyrinth Seal System
Feature: Incorporates a state-of-the-art combination of labyrinth channels, reinforced rubber face seals, and a high-capacity grease reservoir.
Benefit: Creates an formidable barrier against abrasive contaminants like dust, mud, and slurry. This superior sealing technology locks in lubrication, minimizes internal wear, and is the key to maximizing the roller's service life.
Forged Alloy Steel & Induction Hardening
Feature: The roller body is forged from high-grade, heat-treated alloy steel. The running tread surface undergoes deep induction hardening.
Benefit: This process creates an incredibly hard, wear-resistant outer layer while maintaining a tough, shock-absorbent core. The result is exceptional resistance to abrasion, spalling, and impact damage from rough terrain.
Optimized Flange & Bearing Design
Feature: Robust, precisely machined flanges and high-capacity, tapered roller bearings.
Benefit: The flanges provide secure track guidance to prevent derailment, while the heavy-duty bearings ensure smooth rotation under full load, reducing friction and heat generation.

Frequently Asked Questions (FAQ)
Q1: How can I be sure this part (13465919) will fit my SANY excavator?
A: Part number 13465919 is the official OEM designation for this specific support roller across the SY480, SY500, and SY550 models. For absolute confirmation, we recommend cross-referencing this number with the part on your machine or providing your excavator's serial number to our team.
Q2: What is the expected operational life under normal conditions?
A: While lifespan depends heavily on operating conditions and maintenance, our roller is engineered to deliver a service life that meets or exceeds OEM standards, typically ranging from 3,000 to 5,000 hours in standard applications. Regular track cleaning and proper tensioning are critical to achieving this.
Q3: Should I replace all my support rollers at the same time?
A: For balanced performance and to prevent uneven wear on your track chain, we highly recommend replacing support rollers in pairs (both left and right sides) at a minimum. Replacing a full set is the best practice for maintaining optimal undercarriage health.
Q4: Do you offer any warranty on this part?
A: Yes, we stand behind the quality of our products. This SANY Track Support Roller Assembly is backed by a comprehensive 6-month warranty against manufacturing defects.
