Non-metallic idlers
Non-metallic idlers
Compared with traditional metal idlers, non-metal idlers are made of double-protection composite materials and offer several advantages, including flame resistance, antistatic performance, wear resistance (service life up to 30,000 hours), corrosion resistance, no impurity adsorption, low operating noise, and light weight. For the harsh working environment underground in mines, they provide clear advantages. In addition, the internal double-labyrinth sealing design ensures excellent sealing performance. This product has been tested by the Shanghai Coal Research Institute in China, and its actual service life can reach 30,000 hours. It has also been used by multiple mining units, whose actual feedback confirms that the tested service life can be achieved. A long service life means a lower replacement frequency, reduced replacement costs, and less downtime caused by replacement, which greatly improves the production efficiency of manufacturing enterprises. At the same time, a long service life also demonstrates the high quality of our idler products and can significantly reduce the occurrence of production accidents.
All of our products can be flexibly customized. Non-metal idlers can be customized according to the buyer’s actual requirements, including dimensions, sealing structure, and the thickness of the non-metal pipe body. Mining cable hooks can be customized in terms of suspension method, dimensions, and thickness according to the user’s actual application needs. Hydraulic seals can also be customized in terms of size, structure, and thickness.
As a source manufacturer, our company is equipped with complete production lines and has independent design capabilities and efficient production capacity. Our flexible customization can meet buyers’ actual application needs to the greatest extent. Customization method: mutual discussion. Customization process: discuss customization requirements — the buyer provides customization parameters — we produce and send a trial sample.
Non-metallic conveyor idler rollers are designed to replace traditional metal rollers. These rollers are made from polymer composite materials, offering superior flame retardancy, wear resistance, and self-lubrication. The industrial conveyor rollers are engineered to enhance the efficiency and longevity of conveyor belt systems, reducing maintenance costs and supporting sustainable industrial operations.
The idler roller is a key component that supports the weight of the conveyor belt and transported materials. Our company has independently developed non-metallic idler rollers made from polyvinyl chloride (PVC) and ultra-high molecular weight polyethylene (UHMWPE), utilizing chemical by-products as raw materials.
Each roller is composed of a polymer composite body, flexible bearing housing, bearings, cold-drawn shaft, sealing device, and shaft collar. It incorporates proprietary technologies such as deep-hole processing for rollers, high-pressure water sealing, and noise reduction. Compared with traditional carbon steel rollers, our idler rollers are lighter, more durable, corrosion-resistant, and fire-retardant
Conveyor idler rollers advantages
◆ Material Benefits: Constructed from ultra-high molecular weight composites, these non-metal rollers exhibit high wear resistance, self-lubrication, and non-adhesiveness, significantly reducing friction and extending belt life.
◆ Design Features: The embedded combination design ensures stability under load, while the special material of the bearing seat provides non-heat-conductive and high-temperature resistant properties, enhancing product performance and safety.
◆ Sealing Structure: A double labyrinth design effectively isolates the bearing, ensuring long-term, maintenance-free operation and preventing contamination that could lead to belt and roller damage.
Non-metallic rollers are widely applicable across various industries, including food, pharmaceutical, electronics, chemical, and mining, where they meet hygiene standards, prevent cross-contamination, and withstand corrosive environments.

Non-metal rollers refer to rollers made of non-metallic materials . Compared with traditional metal rollers, non-metal rollers have the advantages of flame retardancy, light weight, corrosion resistance, wear resistance, and low noise, so they have been widely used in modern industrial production.
The cable clamp for coal mining machine is made of stamped steel plate as the skeleton and high-density polyethylene through injection molding.
There are a large number of flammable and explosive components such as gas dust in coal mines, and there are many metal equipment and instruments. When the equipment is moved and used, it is very likely to collide with the cable hook, which will produce sparks and lead to explosions.
The dustproof seal is a single-acting seal that is installed by extruding the outer diameter. It can effectively prevent dust and dirt from entering, and allow the residual oil to flow back.
The Y-ring is designed as a static seal for the cylinder, which can replace the traditional O-ring/retaining ring combination. Through its unique design and material, the allowable extrusion gap can reach 0.4mm at a pressure of 500bar.
Piston rod seal, double-lip design has better sealing effect, and polyacetal back-up ring is better under pressure.
The piston seal is a two-way seal, used in conjunction with two piston guide rings, and has a two-way sealing effect.
