Durable High Precision Gears 13.5mm Derailleur Nylon Duplex Gear With 0.5m Modulus

 

 

Plastic duplex gears have a double gears design with different reference circles but same modulus , speed for big reference circle gear is slower than speed for small reference circle gear when they are driven under same power , this design is used to driven system with multiple purposes .

 

Material

Duplex gears are made from plastic nylon ( PA 66 )

Features

 

Wear resistance

 

Good self-lubricant

 

High mechanical property

 

Resistant high temperature

Normally , plastic nylon duplex gears can be operated smoothly at temperature 150℃ and thermal deformed temperature is up to 250℃ when parts with glass fiber .

 

Perfect elongation

Elongation at break is 2.2% according to ISO 527 testing method .

 

Corrosion resistance

 

Good insulation

Specific volume resistance is 1.83×1015 and resistance to high breakdown voltage support part to be good insulated .

 

Resistant impact

60 – 80 KJ/M2 normally .

 

Resistant fire

Generally , the fire resistance is UL94V-2 and UL64V-0 for special parts .

 

 

Resistance to low temperature

Parts can be workable at -30℃

 

Environment friendly

Plastic nylon duplex gears meet RoHS or REACH environmental production standard .

 

 

More plastic gears we manufactured

We provide more plastic gears except duplicate gears , eg , spur gears ,bevel gears ,plastic gears for reducer ,worm gears and involute gear .
