X678 698HT Trolley wheel

Description

The X678 and 698HT heavy duty trolley wheels are high-precision industrial components engineered for the most demanding 6-inch pitch overhead conveyor systems. Designed to navigate I-beam tracks with maximum smoothness and reliability, these wheels feature a reinforced structure capable of supporting massive product loads in continuous production environments. Whether used in automotive assembly, steel processing, or heavy logistics, the X678 and 698HT wheels provide the superior rolling efficiency and structural integrity needed to minimize friction, reduce motor strain, and ensure the long-term stability of high-tension overhead trolley lines.

Manufactured from high-grade alloy steel with precision-controlled heat treatment and advanced bearing technology, Hangzhou Ocean Industry's trolley wheels deliver exceptional wear resistance and extended service life. Every wheel is produced under ISO9001-certified quality management, ensuring total dimensional accuracy and seamless compatibility with standard X678 and 698HT forged rivetless chains and trolley brackets worldwide.

Key Features

• High-Precision Ball Bearing Design: every wheel is equipped with precision-ground ball bearings that provide ultra-low rolling resistance, ensuring smooth movement and reduced energy consumption for the entire conveyor drive system

• Hardened Steel Outer Races: the outer race of the wheel undergoes rigorous induction hardening to achieve maximum surface hardness, protecting against abrasive wear and deformation from continuous contact with I-beam tracks

• Superior Load-Bearing Capacity: engineered specifically for 6-inch pitch systems, these wheels are built to handle the heavy static and dynamic loads required by automotive body lines and heavy machinery assembly

• Effective Sealing and Lubrication Options: available with high-performance seals to prevent the ingress of dust, paint overspray, and industrial debris, with options for standard grease, high-temperature lube, or oil-mist lubrication

• Forged and Machined Structural Integrity: combined forging and precision machining ensure that each wheel maintains its perfect concentricity, reducing vibration and mechanical noise during high-speed conveyor operation

• Standardized Interchangeability: manufactured to strict international industry specifications, X678 and 698HT wheels are fully compatible with existing OEM trolley brackets, center links, and I-beam track configurations

• Severe-Duty Environment Resilience: available in specialized material grades and with anti-corrosive coatings (zinc or black oxide) to withstand high temperatures in drying ovens or chemical exposure in wash-down areas

Application Range

• Automotive Industry — high-load overhead paint lines, body-in-white transfer, and final assembly conveyor systems

• Heavy Machinery Assembly — transfer of large industrial sub-sections, engines, and transmissions through production cycles

• Steel & Metal Processing — reliable movement of heavy plates, coils, and cast components through severe-duty zones

• Construction Material Handling — stable transport of bricks, tiles, and heavy building products through kilns and ovens

• Foundry & Casting Operations — secure conveying of massive molds and hot castings through severe-duty cooling stages

• Logistics & Large Parcel Sorting — high-speed overhead routing for oversized industrial containers and freight

• Agriculture & Fertilizer Plants — durable conveying in abrasive and corrosive conditions where maintenance access is limited

• General Heavy-Duty Overhead Systems — any industrial conveyor requiring the strength and precision of 6-inch pitch trolley wheels
