Shanxi Langnuo Industrial and Mining Equipment Co., Ltd specializes in manufacturing and supplying a wide range of conveyor rollers and idlers for bulk material handling. Our offerings include galvanized rollers for light industrial continuous conveyors, complete roller conveyor systems, spare parts, and related peripheral hardware. These products are widely used in mining and bulk material handling industries.
Our company is ISO9001:2015 certified and holds an industrial production license issued by the General Administration of Quality Supervision, guaranteeing both quality and reliability.
Material: Conveyor rollers are typically made from high-quality steel, such as Q235 carbon steel or SS304 stainless steel, ensuring they can handle heavy loads and withstand long-term wear.
Structure: A carrying roller generally consists of a cylindrical roller body, shaft, and bearings. The roller body supports the weight of the load, the shaft connects the roller to the conveyor frame, and the bearing allows smooth rotation of the roller body.
Bearing Types: Common bearings for carrying rollers include deep groove ball bearings, spherical roller bearings, and tapered roller bearings. The choice depends on the conveyor’s load capacity, operating speed, and environmental conditions.
Applications: Carrying idlers are widely used in mining, construction, and manufacturing industries, enabling efficient transport of heavy goods over long distances and facilitating easier material handling in conveyor systems.
Langnuo has over 12 years of experience in the design and manufacture of conveyor rollers. The company leverages advanced technology and automated production processes to ensure high-quality and efficient manufacturing. Langnuo’s production capabilities include:
· Automated mechanical roller line
· Drumline production

This integration of advanced machinery and automation ensures precision, consistency, and reliability in every conveyor roller produced.
Solid design, suitable for various production lines.
The bearing housing and steel tube are assembled and welded with a concentric automatic.
Cutting of the steel tube and bearing is performed with the use of a digital auto device/machine/equipment.
The bearing end is constructed to ensure that the roller shaft and bearing can be firmly connected.
Fabrication of the roller is effected by an auto device and 100% tested for its concentricity.
Roller and supporting components/materials are manufactured to DIN/AFNOR/FEM/ASTM/CEMA standard.
The casing is manufactured with highly composite, anti-corrosive alloy.
The roller is lubricated and free from maintenance.
Working life expectancy is up to 30,000 hours or more, depending on usage.
Vacuum sealed which has withstood anti-water, salt, snuff, sandstone, and dust-proof experiments.
1. The product manufacturing and testing are recorded, and all testing information is documented.
2. For product performance testing, we invite the user to inspect the product throughout the entire process, conducting full performance checks until the product is confirmed before shipment.
1. To ensure high reliability and advanced products, we select domestic or international quality brand-name components for the system.

1. Product delivery: We strive to meet user requirements as much as possible. If there are special requests, we can complete production ahead of schedule. Our company can organize production and installation specially to fulfill user needs.
Idlers are cylindrical rods that extend under and along the conveyor belt. They are the most important component of a trough belt conveyor. Idlers are usually located in the trough-shaped metal support frame under the carrying side to support the conveyor belt and the materials.
· Properly support and protect the conveyor belt.
· Provide appropriate support for the load being conveyed.
· Belt conveyor idlers for bulk materials are designed to contain drums of various diameters.
· Rollers are fitted with antifriction bearings and seals, and mounted on a shaft.
· Frictional resistance of the idler affects belt tension and power demand.
· Roll diameter, bearing design, and sealing requirements are the main factors affecting frictional resistance.
· Correct selection of roll diameter, bearings, and shafts depends on service type, load carried, belt speed, and operating conditions.
· Stable running with good quality and minimum maintenance.
· Low vibration and long lifespan.
· Dustproof and waterproof.
· High-accuracy steel pipes ensure rollers/idlers run with low vibration and less noise.
· Carrying Idlers: Located on the support side.
· Return Idlers: Located on the return side.
· Many types and functions exist depending on specific applications.
· Coal mines
· Metallurgy
· Machinery
· Ports
· Construction
· Electricity
· Chemical industries
· Food packing
· Idlers endure over 70% of resistance in a conveyor system.
· Conveyor rollers support both the conveyor belt and the material.
· Available roller types include steel, nylon, ceramic, and rubber.
