Transmission Roller Chain
What is the Transmission Roller Chain?
Roller chains are the most widely used rigid meshing transmission components in industrial transmission systems, consisting of five core structures: outer chain plate, inner chain plate, pin, bushing, and rollers. Relying on the precise meshing of rollers and sprockets, they achieve efficient, stable, and synchronous power transmission. Compared to belt drives, they do not slip; compared to gear drives, they offer a longer range of motion and lower installation and maintenance costs.
Models
Types of Roller Chain
- Standard Precision Roller Chains (Single/Double/Multi-Row)
Covering national standard models such as 06B, 08B, 10A, 12A, 16A, and 20A, as well as the full range of American and Japanese standard models (ANSI and JIS). Made of high-quality manganese steel, CNC precision stamping ensures accurate pitch and uniform clearance. Smooth operation, low transmission error, and high versatility. Primarily used in light to medium load applications such as automated equipment, packaging machinery, textile machinery, small conveyor equipment, and general transmission equipment.
- High-Strength Heavy-Duty Roller Chains
Upgraded and optimized for heavy-load, impact, and continuous operation conditions. Thicker high and low chain plates, thicker solid pins, and enhanced overall heat treatment significantly improve tensile strength and impact resistance, effectively solving the problems of excessive tensile stress, breakage, and wear common in ordinary chains under heavy loads. Suitable for heavy industrial applications such as mining machinery, metallurgical equipment, construction machinery, port conveyors, and hoisting equipment, significantly reducing equipment downtime.
Stainless Steel Roller Chains: Made of 304/316 food-grade stainless steel, these chains are non-magnetic, rust-proof, resistant to acid and alkali corrosion, and withstand high and low temperatures. They are free from electroplating pollution and offer high cleanliness. Perfectly suited for corrosion-resistant and clean environments such as food processing, pharmaceuticals, chemicals, cold chain logistics, seawater environments, and environmental protection equipment, they meet industry safety standards and can operate stably in humid and corrosive environments for extended periods.
- Customized Roller Chains with Attachments:
K-type, M-type, and A-type attachments can be added as needed. Customized options include extended pins, side-bent chains, widened chain plates, and special pitch roller chains. Primarily used for material conveying, lifting, sorting, and automated production line gripping and conveying scenarios, these chains perfectly adapt to non-standard equipment structures, solving the pain points of standard chains being unable to be installed or matched to conveying conditions.
Features
- Premium Materials, Enhanced Durability
Raw materials are sourced from large, reputable domestic steel mills, with material certificates accompanying each batch to prevent the use of inferior recycled materials. Core components undergo multiple heat treatments including quenching, tempering, and carburizing hardening, resulting in high surface hardness and robust core toughness, balancing wear resistance and impact resistance, and extending service life far beyond ordinary roller chains on the market.
- Precision Manufacturing, More Stable Transmission
Fully automated CNC machining, fully automated assembly, and intelligent testing ensure uniform chain link pitch and high interchangeability, preventing skipping, deviation, and jamming during high-speed operation. Strict control of chain clearance and coaxiality ensures high transmission efficiency, low power loss, and minimal accuracy degradation over long-term operation.
- Corrosion and oxidation-resistant, with wider environmental adaptability.
The carbon steel series roller chains undergo professional blackening and rust-preventive oil passivation treatment to isolate them from air oxidation and dust corrosion, preventing rusting and jamming under normal temperature conditions. The stainless steel series is non-magnetic, acid and alkali-resistant, and resistant to seawater salt spray corrosion. It can be adapted to harsh environments such as humidity, washing, acid and alkali, low temperature and high temperature for a long time, and is not afraid of corrosion and wear under complex working conditions, ensuring stable operation in all weather conditions.

FAQ
Q1: How to select single-row, double-row, or multi-row roller chains?
A1: For light-load, conventional transmission, and low-load equipment, choose single-row roller chains; for medium-heavy-load conditions requiring increased tensile strength and load-bearing capacity, choose double-row chains; for heavy equipment, ultra-high loads, and continuous impact conditions, choose three-row or multi-row roller chains. If you are unsure about your operating conditions, provide your equipment parameters, and our engineers will provide free, accurate model selection.
Q2: What causes a roller chain to lengthen and loosen after a period of use?
A2: The main causes are normal and abnormal elongation. Slight initial stretching is a normal phenomenon during the break-in period of assembly clearance. Significant elongation and loosening within a short period are often due to an undersized chain, excessive load, insufficient lubrication, or severe sprocket wear. It is recommended to use a standard high-strength chain, perform regular maintenance, and regularly check the sprocket wear.
Q3: Can roller chains be customized to non-standard specifications? Do you support special accessories and pitches?
A3: We support full-dimensional non-standard customization. We can customize special pitches, extended pins, high and low accessories, side-bending chains, widened and thickened chain plates, and irregularly shaped roller chains, adapting to various non-standard automation, conveying, and lifting equipment. We can also create molds one-to-one according to drawings and working parameters.
