Material
Nylon Gear
Nylon Gear is evaluated as a brush component material rather than as filament. Use the project load, geometry, mating parts, exposure, cleaning method, and service requirements to select this component material.
Material Overview
A nylon gear is a molded or machined polyamide power-transmission component used to drive or synchronize a brush.
In a finished brush, Nylon Gear is controlled by section geometry, support, attachment, working load, environmental exposure, and the cleaning method used on the assembly. Specify the component together with its mating parts and acceptance criteria; the material name alone is not a complete design.

Frequently Asked Questions
What are the key properties of Nylon Gear brush material?
A nylon gear is a molded or machined polyamide power-transmission component used to drive or synchronize a brush. Direct data: Density: 1.12–1.15 g/cm³; Hardness: Shore D 75–85; Module range: 0.5–8; Use temperature: -20–100°C; Water absorption: 1–9% by PA grade.
Where is Nylon Gear used in cleaning brushes?
Powered appliance, floor-machine and conveyor brushes that need a quiet moderate-load drive interface.
How does filament geometry change Nylon Gear brush stiffness?
Nylon Gear changes brush stiffness through filament diameter, free trim, density, crimp, and contact. Use finer filament and longer trim for conformable contact; use coarser filament, shorter trim, or higher density for stronger displacement or cutting.
When should Nylon Gear be replaced by another material?
Compare Nylon Gear with POM gear, metal gear, PA12 gear, reinforced nylon. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
