DS10/20B-5 Metric DELRIN 500 Moulded Spur Gear 20 Tooth 1 Mod Bored 5mm

Metric Delrin® 500 Plastic Spur Gears: Spur gears are one of the most common type of gears. They have straight teeth and are generally mounted on parallel shafts. They are designed to exchange speed for torque or vice-versa between input and output shafts, dependent on the gear ratios chosen they can step-up / down the output speed or torque.
Lubrication: In most cases where Delrin plastic gears are deployed no lubrication is required especially if used in conjunction with a steel opposite gear. They are suited to running directly on the shaft with no additional bearings required providing the surface hardness of the shaft is suitable, increased surface hardness will extend bearing life. Soft steels, stainless steels and none ferrous metals will not perform well as a bearing surface for Delrin. Delrin 500 gears are ideally suited to dusty or washdown environments in the food industry although excessive contamination will reduce service life notably.
Material: Delrin® 500 has a good tensile strength and corrosion resistance, manufactured to DIN standards. It is a tough, durable material and is readily machineable.
Benefits: High quality, good tensile strength, pre-bored to H8 tolerance, high quality off the shelf component.
Gear Geometry and Modulus or Mod: The reality of gear geometry and modulus is it can become quite complicated but the rule of thumb is to only use gears of the same modulus together.
The modulus of a gear is a ratio calculated from the gear diameter at half its tooth height divided by the number of teeth, gear modulus must be the same between connecting gears in a drive train, bigger mod ratios have fewer teeth and will transfer larger amounts of power, smaller mod ratios will tend to be in faster and quieter applications.
