The JQ® P140 Heavy Duty Offset Sidebar Chain is a robust industrial conveyor chain designed for high-load and high-impact material handling applications.
Manufactured according to ISO 1977 / DIN 8187 standards, this chain features:
Heavy-duty alloy steel construction for maximum strength
Offset sidebars for reliable support and attachment of flights, buckets, or hooks
Optimized pin and roller design to resist wear under high tension and impact
This chain is ideal for steel mills, cement plants, bulk material handling, and heavy industrial conveyors, ensuring safe and efficient operation even under extreme conditions.
Heavy-Duty Construction
Thick plates, oversized pins, and rollers provide high tensile strength and impact resistance
Offset Sidebar Design
Allows attachment of flights, buckets, hooks, or custom fixtures for material transport
Advanced Heat Treatment
Case-hardened pins and rollers increase wear resistance and service life
High Load Capacity
Suitable for heavy bulk materials, large parts, and high-tension conveyor systems
Reliable Operation
Resistant to bending, fatigue, and elongation under extreme working conditions
