Developed exclusively for industrial elevator transmission systems, Leesolu’s reinforced glass fiber nylon sprocket is made of enhanced polymer composite material with 30% to 33% glass fiber filled in PA66 base, manufactured via precision integrated injection molding. We provide two specifications: drive sprocket and driven sprocket, which can directly replace traditional carbon steel, cast iron and stainless steel sprockets of the same size. It is an optimal solution for upgrading elevator transmission components while cutting costs.
This product outperforms traditional metal sprockets in mechanical strength, wear resistance and corrosion resistance, with a greatly extended overall service life. The keyway of the drive sprocket is embedded with a stainless steel transmission insert, fundamentally eliminating the risk of keyway deformation and slippage for more stable and reliable transmission under heavy-duty working conditions. Manufactured strictly in line with the standard of 24 teeth and 31.75mm double pitch, the sprocket boasts industry-leading tooth profile accuracy. It is ready for use right after installation with no modification to the original equipment structure, effectively reducing maintenance downtime and retrofit costs.
Solve 7 Major Pain Points of Traditional Sprockets, Reduce Costs and Boost Efficiency in All Aspects
Pain Points of Traditional Metal Sprockets
Solutions of Reinforced Glass Fiber Nylon Sprocket
Carbon steel / cast iron materials are prone to rust and corrosion, with extremely short service life in acid-alkali environments
The polymer base material resists acid, alkali and rust, with service life increased by over 5 times in humid / corrosive environments
High dead weight and large moment of inertia, strong start-stop impact and high energy consumption
With a density only 1/7 of steel, it features small moment of inertia, effectively reduces motor load and saves energy by 15%-20%
Loud metal friction noise and poor workshop working environment
The material has self-lubricating property, cutting operating noise by more than 30dB and improving the workshop working environment
High metal hardness easily wears out chains, leading to frequent consumable replacement
Reasonable hardness matching enables more uniform wear with the chain, extending chain service life by 2-3 times
Welded and spliced structure is prone to cracking and desoldering, resulting in high equipment failure rate
Integrated injection molding with no welding or seams, uniform structural strength, reducing equipment failure rate by 80%
Rough surface easily adheres to materials, causing chain jamming and chain dropping
Dense and smooth surface with low friction coefficient, no material adhesion or chain jamming, ensuring smoother material conveying
High purchase cost of stainless steel sprockets, putting pressure on O&M budget
With comprehensive performance comparable to stainless steel sprockets, the purchase cost is only 30%-50% of stainless steel ones, achieving significant cost reduction
Five Core Advantages for Stable and Reliable Transmission Performance
1. High Strength & Wear-Resistant Structure, Stable Operation Under Heavy-Duty Conditions
The base material has a tensile strength of up to 200MPa, close to that of ordinary carbon steel, and can withstand continuous heavy-duty transmission. The key transmission position of the drive sprocket adopts a stainless steel embedded keyway design, combining metal transmission strength with polymer wear resistance, completely eliminating the risk of keyway deformation and slippage. High-toughness PA66 is perfectly compounded with glass fiber, featuring impact resistance, wear resistance, scratch resistance and cracking resistance, with a service life more than 3 times that of ordinary nylon sprockets.
2. Wide Temperature Range Weather Resistance, Stable Performance in Extreme Environments
Heat deflection temperature reaches 180-250℃, maintaining no deformation during continuous operation in high-temperature workshops. Excellent low-temperature performance, retaining good ductility under extreme low temperature without brittle fracture risk. Stable material performance, no powder shedding and no deformation during continuous operation, resistant to various acid and alkali corrosion, suitable for special working conditions such as chemical production and food cleaning.
3. Precise Tooth Profile Design, Accurate and Efficient Transmission
The double-pitch tooth profile is formed by precision mold in one injection, with tooth pitch error ≤±0.05mm, reaching industry-leading accuracy. It achieves precise gap-free meshing with elevator chains, no chain jamming during heavy-load start and stop, no chain dropping during high-speed operation. Transmission efficiency is as high as 98% or above, effectively improving the overall operating efficiency of the elevator and reducing energy loss.
Adopting advanced integrated injection molding process, the product has no welding, no seams and no burrs. Uniform material density, stable structure, no cracking and no peeling, with high quality consistency. Smooth and burr-free surface will not scratch chains and conveyed materials, fully suitable for industries with high hygiene requirements such as food and pharmaceuticals.
5. Standardized Interchangeable Design, Convenient Installation and Maintenance
Manufactured strictly in accordance with national standard dimensions, 100% interchangeable with metal sprockets of the same specification. No equipment modification is needed when replacing old sprockets; direct installation can be completed in minutes, greatly shortening maintenance downtime.
