Nylon Spur Gears

Custom Nylon Spur Gears — Manufacturer & Supplier in China

Raydafon makes nylon spur gears to order in its own workshop in Ningbo, China, for OEMs that need a specific tooth count, bore, hub or material rather than a catalogue part. Send a dimensioned drawing or a sample gear and we will either cut or mould to match it, in the polymer grade that fits your load, speed and environment. Because we handle both moulding and machining, the same project can start with a machined prototype and move to a moulded production part once the geometry is fixed — which removes the tooling risk from your first samples.

Typical buyers are builders of automatic assembly and control machines, semiconductor handling equipment, medical devices, machine tools, parking systems and transport equipment, where a self-lubricating gear removes an oiling point from the maintenance schedule. If you need a plastic gear family rather than a spur gear alone, see the full plastic gear range; if the duty is beyond polymer, the metal spur gear line from the same factory covers it.

Specifications and Available Options

Please note: hardening, milling, grinding, anodizing and zinc plating are metal-gear processes and do not apply to polymer gears. If a drawing specifies those treatments, we will flag it and propose the polymer equivalent — glass-filled grade, moulded finish or a machined plastic part — before quoting.

Key Advantages

• Self-lubricating, no oiling pointWithout a lubricant film to maintain, the gear removes an oil chamber, seals and a recurring service task from your design. Printers, dispensers and office equipment run for months of daily use without the drag or noise that a dry metal gear pair develops.
• Quiet by material and by geometryPolymer damps vibration instead of ringing like steel, and the fibre-reinforced grades hold tooth form well enough to keep mesh quiet across the batch. Workshops and office equipment see a clear drop in noise after switching from metal gears.
• Wear life beyond ordinary plasticFibre-reinforced PA66 gives roughly 60% longer wear life than standard nylon, so a gear that previously needed replacing can run through extended high-frequency duty on an assembly line with negligible tooth-surface loss.
• Corrosion and chemical resistanceNylon does not rust, and it tolerates humid, mildly acidic and mildly alkaline environments, plus many cleaning agents. That makes it suitable for wash-down areas and outdoor equipment where a plated metal gear would eventually break down.
• A fraction of the weight of metalLow mass cuts the inertia of the driven parts, which matters for hand-held devices, drones, lightweight actuators and any mechanism where every gram affects battery life or handling.
• Prototype to production under one roofMachined prototypes let you validate geometry before committing to tooling, then the same workshop moves the part to moulding for volume. You keep one supplier, one tolerance reference and one inspection standard throughout.
• Flexible materials and standardsSeven polymer families and five gear standards (ISO, DIN, ANSI, JIS, BS) mean the same drawing can be produced in the grade your application actually needs, rather than the one grade a supplier happens to stock.
• Factory-direct pricing on volumeMoulding, machining, inspection and packing are all in-house, so there is no trading margin between you and production, and unit cost falls predictably as quantity rises.

Nylon vs Metal Spur Gears: When Plastic Is the Right Choice

A nylon spur gear is not a weaker substitute for a steel one — it is a different design decision. Plastic wins where the load is moderate, the speed is high enough that noise matters, and lubrication is expensive or impossible to maintain. It loses where the torque is high, the temperature is sustained above the polymer's limit, or the duty involves continuous shock that would deform the teeth.

In practice the most durable arrangement is often a nylon gear running against a steel or brass pinion: the polymer wears in preference to the metal, the mesh stays quiet, and the metal part carries the higher stress. Tell us the mating gear material and we will advise on backlash and centre-distance allowance, since plastic and metal expand at different rates.

Buyer FAQ

• Can you make a nylon spur gear to my drawing or from a sample?Yes. Send a dimensioned drawing or the sample gear with the module, tooth count, bore, face width and material grade. We confirm whether the part suits moulding or machining, quote both if relevant, and can produce a machined prototype before any tooling is committed.
• Which material should I choose — PA, POM or PEEK?PA (nylon 66) is the general-purpose choice, and fibre-reinforced PA66 gives roughly 60% longer wear life than standard nylon. POM suits applications where dimensional stability and backlash control matter more than impact tolerance. PEEK or PPS are for elevated temperature or chemically aggressive service. Tell us load, speed and environment and we will recommend one.
• What tolerance can you hold on a plastic gear?It depends on the feature, the module, the wall thickness, the material and whether the part is moulded or machined — machined parts hold tighter tolerances than moulded ones. State the centre-distance and backlash your assembly needs and we will confirm what is achievable before quoting.
• Does the gear need lubrication?No in normal duty; nylon and POM are self-lubricating. For high-speed or heavily loaded continuous running, a small amount of compatible grease can extend life, and we will say so at quotation stage if your duty benefits from it.
• What are your sample, lead time and payment terms?Samples are priced from USD 2 to USD 100 depending on size and material, with express freight paid by the customer. Sample lead time is 20 business days and bulk production is 25 days. Payment terms are T/T or L/C, and packing is a plastic bag plus carton, or a wooden case for larger quantities.
• Can you supply the matching pinion as well as the nylon gear?Yes. Supplying both halves of the mesh from one workshop means the backlash, centre distance and tooth form are matched at the design stage rather than adjusted on site. Send the pair drawing, or the load and ratio you need, and we will quote both parts.
