Product Description

Product Introduction

Our A Series cotter-pin type short-pitch precision roller chains stand at the forefront of small to medium-sized transmission systems. These chains are synonymous with simplicity, economic practicality, and ease of maintenance. When selecting the ideal chain, prioritize load capacity, operational speed, environmental factors, and lubrication conditions. Diligently checking the cotter pins' secure state can vastly extend the chain's lifespan. For demanding precision or challenging environments, consider upgrading to a roller chain with a sealing ring or opt for a silent chain to enhance performance and sustain durability.

Transmission chains serve as vital components in mechanical transmission, effectively conveying power and motion. By engaging with sprockets, these chains facilitate the transformation of rotary or linear motion.

 

Precision conveyor chains are crafted with a series of bearings, precisely aligned and anchored by chain plates. Each bearing features a pin shaft and a sleeve, enabling the chain's rollers to rotate seamlessly.

Stainless steel chains, crafted from stainless steel wire or round steel, are available in both short-link and long-link configurations, offering reliable durability and strength.

 

Our agricultural machinery chains include feeding chains with P2-type plates, lifting chains with Ld2-type plates, and corn harvesting chains featuring WK-type plates, designed for robust performance in the field.

 

Traction chains have widespread applications, serving forklifts, port stackers, textile machinery, parking garages, drilling rigs, aerial work platforms, and pipe benders with commendable efficiency.
