Product Description

Cottered Type Short Pitch Precision Roller Chain (A Series) - Product Introduction

Overview

Our A Series Cottered Type Short Pitch Precision Roller Chain is a standardized, high-precision power transmission component manufactured in strict accordance with ISO and ANSI industrial standards. Designed for general industrial transmission and conveying systems, this cottered-version roller chain features a specialized open cotter pin fastening structure, enabling convenient installation, disassembly, and routine maintenance. It balances outstanding structural stability, dimensional precision, and cost-effectiveness, serving as a reliable and versatile transmission solution for diverse mechanical equipment.

Superior Structural Design

Different from standard spring clip roller chains, this cottered type chain fixes outer link plates and pins via sturdy open cotter pins. The locking structure is simple, firm, and anti-loosening, effectively avoiding chain separation and failure during long-term high-speed operation and heavy-load working conditions. The short pitch precision design ensures ultra-precise dimensional uniformity of each chain link, minimizing running deviation, vibration, and noise during equipment operation. Meanwhile, the standardized link structure guarantees excellent compatibility and interchangeability with standard A-series chain accessories, greatly improving equipment assembly flexibility.

Premium Material & Durable Performance

Crafted from high-grade 40Mn and 30 alloy steel materials, the chain undergoes strict integral heat treatment including quenching and tempering, achieving high tensile strength, excellent surface hardness, and strong wear resistance. The precision machined rollers and pins feature smooth surface finish and low friction coefficient, effectively reducing operating wear and extending service life. With stable mechanical properties, the chain resists deformation and fatigue under continuous operation, ensuring consistent and reliable transmission performance in long-cycle industrial work scenarios. Multiple specifications from 10A to 240-1C are available to meet different load and speed requirements.

Core Advantages

Easy Maintenance: Cotter pin connection allows quick disassembly and replacement, ideal for equipment requiring frequent inspection and maintenance, saving time and labor costs.
Stable Transmission: High-precision pitch control ensures smooth operation, low noise, and high transmission efficiency, with no jitter or slipping during operation.
Strong Adaptability: Excellent structural toughness and load-bearing capacity, adaptable to normal temperature, conventional dust and mild corrosive industrial environments.
Standardized & Interchangeable: Fully compliant with international industry standards, compatible with global standard sprockets and transmission parts, easy for replacement and matching.
Cost-Effective: Durable construction reduces replacement frequency and equipment downtime, lowering overall operating costs for customers.

Wide Applications

This A Series cottered short pitch precision roller chain is widely applicable to various industrial mechanical transmission and conveying equipment, including textile machinery, packaging machinery, food processing equipment, garment machinery, mining machinery, general conveyor systems, electric vehicle transmission devices, and other general industrial mechanical equipment. It is especially suitable for medium and low-speed, medium-load working scenarios with regular maintenance demands.

Packaging & Supply Service

We provide standardized export packaging including plastic bag inner packing and neutral/color box outer packing, with wooden case reinforcement for long-distance transportation to prevent damage. We support customized specifications, bulk wholesale, and fast global delivery. Strict factory quality inspection is implemented for each batch of products to guarantee stable quality and qualified rate, providing customers with reliable OEM and ODM supporting services.
