When utilizing metal gears and resin gears, have you encountered any of the following issues? "Resin gears have a short lifespan. I want stronger resin gears." "The gears are heavy. I am considering lightweighting the gear train." This document provides technical information on how to solve such common concerns with Rignite Gears, along with points to consider during selection! 【Features of Rignite Gears】 ■ Achieves long lifespan and high transmission capability due to high strength ■ Enables lightweighting as it has a density that is 1/5 that of metal ■ Allows for low noise due to good vibration damping properties ■ Capable of small lot production starting from just one piece 【Product Lineup】 ■ N Type Characterized by low water and oil absorption rates and high thermal deformation temperature, resulting in good dimensional stability. ■ BC Type Features the highest thermal deformation temperature and high impact resistance. It also has a friction coefficient comparable to MC nylon. ■ Carbon Type Characterized by the highest tooth surface strength and exceptional wear resistance, leading to a long lifespan. *For the technical documentation on "Rignite Gears," please refer to the PDF data available for download.

"Rignite Gear" is a resin gear (transmission gear) that achieves one-fifth the weight of metal and low specific gravity. It contributes to the lightweighting of all types of machinery, including machine tools and industrial equipment. Additionally, it does not require lubrication oil and helps reduce noise, thereby minimizing environmental impact. 【Features】 ■ Achieves long lifespan and high transmission capability due to high strength ■ Enables lightweighting due to one-fifth the specific gravity compared to metal ■ Capable of low noise levels due to good vibration damping properties ■ Small lot production is possible starting from just one unit *Please view the PDF data of the "Rignite Gear" catalog available for download.

At Lignite, we specialize in manufacturing special resin rollers that place particular emphasis on heat resistance, wear resistance, chemical resistance, and durability. We have established a consistent production system from material development to molding and final processing of components, striving to meet the needs of our users. In particular, we are a manufacturer with dedicated materials for under rollers used in twisting machines. **Features of Lignite Under Rollers** - **Protection of Disc Rollers** Reduces wear and damage to disc rollers. - **Low Vibration and Low Noise** Achieves low vibration and low noise with appropriate compression elasticity and good vibration damping characteristics. - **Reduced Maintenance** With a specific gravity that is 1/5 that of metal, the under rollers are lightweight, making maintenance easier. - **Choice of Materials** Depending on the model you are using and other conditions, you can choose from two types of materials (BC-3000, RB500B).

At Lignite, we manufacture large, thick, and massive resin molded products using various presses, including a 1500-ton press and a 500-ton press. The 1500-ton press is used to produce large resin molded products (such as gears and rollers) for various industrial machines, including twisting machines and textile machinery. We are also capable of producing non-asbestos molded bodies and arch-shaped bow guide plates. 【Lignite's Molded Products】 ■ Large Molded Products: Large and thick molded products that push the boundaries of molding technology ■ Material Development Products: Molded products developed from materials that only a resin manufacturer can provide ■ CFRP Molded Products: Production of molded products using carbon fiber *For more details, please refer to the PDF materials or feel free to contact us.

"Rignight Gear" is a heat-resistant resin gear that achieves high durability and high transmission capability while having a low specific gravity of 1/5 compared to iron. By using it as a substitute for other resin gears, it enables high transmission capability in various gear trains such as machine tools. In addition to being oil-free, its excellent vibration damping characteristics contribute to low noise and low vibration. It has a wide range of sizes from 40 to 2000 mm in outer diameter and can accommodate orders from a single piece. 【Features】 ■ Achieves long life and high transmission capability due to high strength ■ Excellent dimensional accuracy due to low water and oil absorption rates and high heat resistance ■ Usable in water and oil baths ■ Three types with different characteristics are available *For more details, please refer to the materials. Feel free to contact us with any inquiries.

Our company is focusing on initiatives for carbon neutrality. We are actively engaged in research and development of materials for energy storage systems aimed at green electricity, technologies for large-scale hydrogen supply and utilization towards the realization of a hydrogen society, and CO2 recycling using activated carbon. 【Details】 ■ GPS for LIB: Development of materials for batteries aimed at green electricity ■ GPS for FC: Technologies for large-scale hydrogen supply and utilization towards the realization of a hydrogen society ■ Activated carbon from LPS: CO2 recycling using activated carbon *For more details, please refer to the materials.

The oldest resin, "phenolic resin," is now available in spherical form! Particle size control is possible in the range of 5μm to 500μm! Being spherical, it has excellent flowability! 【Features】 ○ Spherical shape provides good flowability and allows for high filling. ○ High fixed carbon content enables the production of spherical carbides through firing and heat treatment. ○ High purity with no ash content. ○ The molded products possess heat resistance, mechanical strength, chemical resistance, and electrical insulation comparable to conventional phenolic resins. For more details, please contact us or download the catalog.

The "BCS Board" is a porous material molded from our original spherical phenolic resin "LPS." Due to its porous nature, it has good air permeability, which varies depending on the size of the spherical phenolic resin used. Additionally, we also offer a porous carbon material that has been fired and carbonized, so please feel free to contact us if you are interested. 【Features】 ■ Porous, allowing for air permeability ■ The air permeability of the porous material changes by varying the particle size of the spherical phenolic resin used ■ A porous carbon material that has been fired and carbonized is also available ■ The porous carbon material is resistant to acidic and alkaline chemicals *For more details, please refer to the PDF document or feel free to contact us.
