Note:Gears are offered single.Product Description:Name: 45 Degree Helical GearModel: 1MMaterial: 45# steelTooth:15 Tooth -60 ToothProcess hole:10mm(Different batches may result in different inside holes)Rotation direction: Right rotationPressure angle: 20 degreesSpiral angle: forty five degreesFeatures: 1. 45 diploma helical gear, nice meshing, smooth rotation, low noise, excessive torque, and excessive overlap. It reduces the weight on each pair of gears and improves the bearing potential of the gears. It can be paired with any number of enamel without transmission ratio.2. Buy 2 to type a 90 degree transmission torque staggered gear. forty five degree helical gear can be utilized as a ninety degree steerage gear.3. Standard inner gap with top screw gap for simple installation4. This tools adopts a hobbing process, and the inner hole is precision machined. The meeting clearance needs to be elevated by way of about 0.2mmThe following is the theoretical Centre-to-centre distance of each tooth quantity assembly, for reference only, the categorical data shall be discipline to the actual situation, thank you!Remarks: If you've special needs, please touch us, we can customise consistent with your needs!Package Include:According on your Choose!
