The KNSU1-70J17 is a plastic spur gear featuring a steel core, designed for applications requiring durability and precision. It has a module of 1 and consists of 70 teeth, with a finished bore diameter of 17mm. The gear is made from MC nylon fused to a metal core, providing a wide operational temperature range and good dimensional stability. The allowable torque for this gear is 5.12 N¬?m, with a corresponding weight of 0.40 kg. The backlash is rated at 0 to 0.36 mm, ensuring minimal play in gear engagement. This product is suitable for applications where reduced weight and corrosion resistance are advantageous, although it is recommended to pair it with steel gears to mitigate heat generation without lubrication.
