We started making belts in 1999 with a single production line and a simple idea: Chinese manufacturers could build products as good as anyone else — if they stopped cutting corners. Twenty-five years later, we’re still here, still making belts, and still learning that the hard way is usually the right way.
Today, Longyi Rubber Products Factory (brand: LYBELT) operates from Xingtai, Hebei Province. We’ve developed 130+ proprietary rubber compound formulations, earned [IATF 16949 certification](/certifications/), and ship to distributors in over 100 countries. But the numbers don’t tell the whole story.
At present, the company has more than 130 rubber belt material formulations, can produce tens of thousands of belt varieties, Suitable for the world’s mainstream passenger auto models, commercial vehicle models, widely used in agriculture, machinery and equipment, more than 80% of the products are exported to Europe,the United States, Australia, the Middle East, Southeast Asia and other more than 100 countries and regions, is many internationally renowned auto parts sellers, and rubber belt sellers long-term partners.

Here’s the truth about our history: it’s not a straight line of success. It’s a series of lessons, some of them expensive.
We’re one of the few Chinese rubber belt manufacturers holding [IATF 16949 certification](/certifications/). This isn’t just a badge — it’s a system. Defect prevention built into every process. Statistical process control. Full traceability from raw material to finished product. The same quality requirements that Tier-1 automotive suppliers must meet.
130+ proprietary rubber compound formulations developed since 1999. EPDM, CR, HNBR, NBR, NR, FKM, and custom blends. We can engineer belts for virtually any operating environment — from -40°C Arctic conditions to +200°C industrial processes. When a customer brings us a weird application, we don’t say “we can’t do that.” We say “let’s figure it out.”
Our 2018 aviation product certification sets us apart from virtually all competitors. The precision, testing rigor, and documentation standards required for aviation components are now embedded in our standard processes. You benefit from aerospace-level quality control even if you’re buying agricultural belts.
Five major product lines under one roof:
80%+ of our production is exported to over 100 countries. We understand international quality standards, packaging requirements, shipping logistics, and documentation needs. When you work with us, you’re not our first export customer — you’re benefiting from two decades of international trade experience.
We’re a manufacturer, not a trading company. You work directly with the people who make your products. This means better pricing (no middleman markup), faster communication (no telephone game), greater customization flexibility (we control the production), and complete quality traceability (we know exactly what went into your belts).
Our factory in Xingtai, Hebei Province houses:
Tensile strength testing machines
We can handle orders from 200 pieces (trial orders) to hundreds of thousands of pieces (annual supply contracts). Flexible scheduling allows us to accommodate rush orders when production capacity permits.
The first step in quality control is the selection of high-quality raw materials. Factories rigorously select natural or synthetic rubber, ensuring it meets all necessary performance standards. Additionally, suppliers are strictly evaluated to choose only those who can consistently provide quality materials.
During production, each step is accompanied by meticulous quality checks. Advanced automation systems are used to ensure that the thickness, width, and elasticity of each rubber belt meet the design standards. Real-time monitoring of production lines allows for the immediate identification and resolution of any potential quality issues.
Each batch of finished products undergoes rigorous testing, including tests for abrasion resistance, tensile strength, and long-term durability. These tests ensure that each rubber belt performs excellently in practical applications. Products that do not meet the standards are strictly dealt with, ensuring that only qualified products enter the market.
Through these strict quality control measures, rubber belt factories ensure the high quality of their products. This not only wins the trust of customers but also sets a benchmark for the entire industry. Continuous quality improvement and technological innovation are key to maintaining a leading position in this industry.
In summary, strict quality control is not just the cornerstone of the operation of rubber belt factories, but also a guarantee of their long-term success. By continually pursuing excellence, these factories contribute valuable stability and reliability to the entire field of industrial production.
Quality isn’t something we talk about — it’s something we prove.
