Heavy duty series cottered type roller chains

Product Overview

Heavy Duty Series Cottered Type Roller Chains are precision short-pitch drive chains engineered for heavy load, high impact, and frequent disassembly conditions. Compliant with ISO and ASME/ANSI standards, they feature thicker plates equivalent to the next larger pitch size in standard chains, combining heavy-duty load capacity with easy maintenance.

Core Structure

Key Features

1. Heavy-Duty Load Capacity: Thickened plates deliver tensile strength far exceeding standard A-series chains, ideal for heavy-duty applications.
2. Cottered Quick-Release Design: Individual links can be disassembled and replaced without cutting the entire chain, greatly reducing maintenance costs and downtime.
3. Impact Resistance & Versatility: Reinforced plates enhance impact toughness; reversible for multi-shaft drives and long center distances (≤4m).
4. Standard Compatibility: Available in simplex, duplex, and triplex configurations, with chain numbers from 10AH to 40AH and pitches from 15.875mm to 63.5mm. Compatible with standard A-series sprockets (special sprockets required for multi-strand).
5. Reliable Performance: Roller-bushing rolling contact minimizes wear and maximizes transmission efficiency; black oxide or shot-blasted surface for corrosion resistance.

Applications

Widely used in construction machinery, mining equipment, metallurgical plants, agricultural machinery, port cranes, material handling systems, and heavy-duty transmission applications requiring high load, impact resistance, and frequent maintenance.
