Overview
Custom plastic sprockets for roller chain drives. Quieter, lighter, and corrosion-proof.
CDS Plastics manufactures all types of precision plastic sprockets including drive sprockets, driven sprockets, and idler sprockets for chain systems. Through advanced CNC plastic machining of UHMW sprockets, nylon chain sprockets, and food grade sprockets, we produce replacement sprockets that perfectly engage ANSI standard chains (#25, #35, #40, #50, #60, and larger). Our corrosion resistant sprockets deliver superior performance as drop-in replacements for metal sprockets in harsh environments.
Why Choose CDS Plastics Sprockets
Self-Lubricating Performance Eliminates Maintenance
UHMW sprockets and oil-filled nylon chain sprockets run without external lubrication, eliminating grease contamination in food processing and significantly reducing maintenance labor costs.
Corrosion Resistance in Harsh Environments
Our corrosion resistant sprockets withstand washdowns, chemicals, and outdoor exposure without rust or degradation, typically lasting significantly longer than steel in corrosive applications.
Noise Reduction for Safer Work Environments
Plastic chain drive components reduce noise considerably, helping facilities meet OSHA requirements while improving worker comfort and communication.
Precision CNC Machined for Perfect Chain Engagement
Our CNC machined sprockets hold tooth profile tolerances to ±0.005" ensuring smooth chain meshing, reduced wear, and elimination of chain jumping or binding.
Solutions for Common Chain Drive Challenges
Contamination from Lubrication
Corrosion in Washdown Areas
Excessive Chain Drive Noise

Frequently Asked Questions
Can plastic sprockets handle the same loads as steel?
For many applications, yes. Nylon chain sprockets handle significant loads, and glass-filled versions approach steel strength while maintaining weight advantages. The key is selecting the right material for your torque and speed requirements. Most conveyor and moderate-speed applications work excellently with plastic.
How long do UHMW sprockets last compared to steel?
In corrosive or washdown environments, UHMW sprockets typically last significantly longer than steel because they don't rust. In dry conditions, they may wear faster than hardened steel but replacement sprockets are economical and won't damage expensive chains when worn.
Do plastic sprockets work with standard roller chains?
Yes, our CNC machined sprockets are precision-made to ANSI standards and work perfectly with standard roller chain sprockets. The tooth profiles are identical to metal sprockets, ensuring proper engagement and power transmission.
What's the difference between metal detectable and X-ray detectable sprockets?
These are not interchangeable - they work with different detection systems. Metal detectable plastics trigger metal detectors, while X-ray detectable materials show up on X-ray inspection systems. We also offer ultra detectable plastics that work with both detection methods and include blue coloring for visual detection. Choose based on your facility's inspection equipment.
Can you make split sprockets for installation without removing shafts?
Yes, we regularly machine split hub plastic chain drive components that clamp around existing shafts. This design allows replacement sprockets to be installed without disassembling drive systems, reducing downtime from hours to minutes. We can replicate your existing split design or create new configurations.
