Injection Moulding Corrosion Resistant MC Nylon Industrial Conveyor Rack Gear

🚚 Cycle Count and Wear Life

Conveyor diverter rack drives cycle far more frequently than sliding gate systems — a gate may cycle 20-50 times per day, while a conveyor diverter at the merge point of a busy distribution centre may cycle 2,000-5,000 times per day. MC nylon and PA66 with self-lubricating surface properties are specified for these high-cycle conveyor applications because the rack wears slowly and predictably, with service intervals typically measured in years rather than months.

🦻 Contamination Control

Conveyor racks in food, pharmaceutical, and electronics production environments must not generate metallic wear particles or lubricant contamination. Nylon, POM, and UPE racks satisfy this requirement because: the polymer wears by generating microscopic polymer particles rather than metallic debris; no external lubricant is applied; and FDA-compliant or RoHS-compliant grades ensure the polymer itself does not introduce prohibited substances into the production environment.

⚙ Load and Module Selection

Conveyor product loads are typically light to moderate — 50-500 N tangential force on the rack tooth for most carton and tote conveyor systems. Module M2-M4 in PA66 or MC nylon covers the majority of industrial conveyor rack applications. For heavier pallet conveyors or elevated deck systems above 500 N tangential load, specify a larger module or upgrade to MC nylon — which handles approximately 30-40% more load at the same module and face width than standard PA66.

🔧 Maintenance-free Operation

The self-lubricating property of nylon and POM racks is particularly valuable in conveyor applications where access for lubrication is restricted by guarding, production scheduling, or hygiene requirements. A nylon conveyor rack installed correctly — with proper centre distance, correct module matching, and thermal expansion gaps at section joints — requires no maintenance beyond periodic visual inspection across its full service life.

What polymer should I specify for a food-processing conveyor rack gear?

For dry food-processing conveyor zones, specify PA66 or MC nylon — both are food-safe in contact with dry packaged goods under EU and US food-contact regulations, and both are self-lubricating so no lubricant contamination risk is introduced. For wet zones with wash-down, specify POM acetal or UPE — these materials absorb very little moisture so tooth accuracy is maintained after repeated wetting, and FDA-compliant grades are available for direct food-contact approval. For applications where a formal FDA or EU food-contact compliance letter is required, specify this at the enquiry stage and the appropriate documentation will be supplied with the order.

I do not have a drawing. How do I start a custom conveyor rack project?

You can provide us with a worn or failed rack sample and we will reverse-engineer the specification — measuring the module, cross-section, section length, hole pattern, and material grade from the sample and producing a dimensional drawing for your review and approval before production. If the original specification is known from a parts manual or datasheet, we can produce directly from that information. There is no charge for the reverse engineering drawing service for production orders; a nominal drawing fee applies for development projects, which is credited against the first production order.

How is product quality ensured before delivery without a factory visit?

If no factory visit or third-party inspection is arranged, we act as your quality inspector. On completion of production, we prepare a detailed video showing the production process, dimensional inspection measurements with the measuring instrument and part clearly visible, surface condition, and packaging details. This video is shared before shipment and provides the same visual evidence that a factory visit would provide. For regulated applications requiring a formal inspection certificate, a third-party inspection from SGS or equivalent can be arranged at the customer request.
