II. Core Technology: Forging International Standard Roller Chain Quality
1. Strict Adherence to Global Technical Specifications
All BULLEADCHAIN products strictly comply with EN ISO 606 international standards and EU CE certification requirements. They have passed the Machinery Directive 2006/42/EC compliance assessment, ensuring market access in the EU. They also meet RoHS 2.0 directive restrictions, with metal parts containing lead, cadmium, and other hazardous substances below the limit standards, and plastic coatings free of excessive plasticizers, making them fully suitable for high-standard applications such as electronic and electrical equipment and medical devices. Product model designations follow internationally unified standards. For example, the LL120-2×16-1.5 series double-row roller chains have a pitch accuracy controlled within ±0.5mm, roller surface hardness ≥HRC60, and chain link surface roughness Ra≤0.8μm, reaching top-tier manufacturing standards in the industry.
2. Innovative Breakthroughs in Materials and Processes
High-Performance Material Application: Utilizing high-quality base materials such as 42CrMo alloy steel and 304/316L stainless steel, and employing precise heat treatment processes, the tensile strength of the products is increased by more than 30%, and wear resistance is improved by 20% compared to ordinary carbon steel products.
Precision Manufacturing Process: Through computer-aided design and CNC machining technology, dimensional tolerance control is achieved for key components such as rollers, sleeves, and pins. Combined with surface treatment processes such as galvanizing and chrome plating, the product’s corrosion resistance is significantly improved.
Intelligent Upgrade: The intelligent roller chain, integrated with IoT sensors, enables real-time monitoring of operating status, predictive maintenance, and remote diagnostics, reducing maintenance costs for customers by more than 20%.
III. Full-Scenario Coverage: Empowering Efficient Operations Across Multiple Industries Globally
1. Core Application Area Solutions
2. Customized Service Capabilities
BULLEADCHAIN provides end-to-end customized services, from parameter design to mass production, to meet the specific needs of specialized industries. Core parameters are precisely calculated using the pitch formula (pitch = chain plate thickness × (1 + √(number of rows² + 1.41² × number of rows))). Key indicators such as chain plate thickness and roller diameter are optimized based on customer operating conditions. For example, the 24A series roller chain (76.2mm pitch) customized for oil drilling rigs can withstand heavy-load impacts and high-temperature environments. IV. Selection and Maintenance Guide: Making Transmission More Efficient
1. Three Key Elements for Scientific Selection
Working Condition Matching: Select single-row/multi-row chains according to load level (e.g., for torque 500 N·m, a 6-row chain is recommended). Prioritize A-series products for high-speed operation, and B-series products are suitable for general transmission.
Parameter Verification: Measure the chain plate thickness and roller diameter with calipers, and confirm the model using a pitch reference table to avoid jamming or slippage caused by pitch deviation.
Material Selection:Select stainless steel for humid environments, alloy steel for heavy-duty applications, and special surface treatment processes for corrosive conditions. 2. Professional Maintenance Recommendations
Daily Inspection: Check chain tension and wear daily to avoid abnormal tension (recommended tension 0.8-1.2kN);
Lubrication and Maintenance: Regularly add specialized lubricant. Under harsh operating conditions, shorten the maintenance cycle to 500-800 hours;
Replacement Standard: Replace the chain immediately when wear exceeds 3% of its initial length, or when cracks appear on the roller surface or the chain plates are deformed.
