KG Geared Spiral Bevel Gear BG2.5S 20L30R-12H BG2.5S 20L30R-12H 1 pc

Catalog number: BG2.5S 20L30R-12H Features: ●Compared to gear cutting products, it can rotate at high speeds and is quieter. ●High strength specifications. After induction hardening of the teeth, the teeth are polished to a high precision. As a result, bending strength and tooth surface strength are improved by more than 20% compared to gear cutting products. ●Can be customized to high precision. The outer circumference of the hub and the outer circumference of the teeth are polished to maintain precision and ease of processing when additional processing is performed by the customer. (The outer circumference of the teeth is chamfered parallel to the axis, so it can be chucked with high precision.) ●Ideal for high-speed operation. ●Compared to gear cutting products, it can rotate at high speeds and is quieter. Applications: ●Used for general industrial machinery, high-speed rotating tool equipment, etc. Specifications: ●Module: 2.5 ●Number of teeth: 20 ●Pitch circle diameter (mm): φ50 ●Assembly distance (mm): 55 ●Hole diameter (mm): φ12 ●Total length (mm): 30.81 ●Tooth width (mm): 15 ●Tooth tip circle diameter (mm): φ53.5 ●Hub outer diameter (mm): φ44 ●Hub length (mm): 15.49 ●Hole length (mm): 28 ●Tooth ratio: 1:1.5 ●Tooth tip angle: 39°24′ ●Gear precision: Tooth surface ground finish ●JIS B 1704 Class 1 ●Pressure angle: 20° ●Twist angle 35° ●Backlash can be set to 30μ or less Material/Finish: ●SCM440 (Chromium molybdenum steel) Caution: ●Avoid meshing with gear cutting products or other products, and use only with our gear cutting products. ●For high-precision customization, be sure to use a raw-jaw scroll chuck and make the runout of the product's hole surface as close to zero as possible.
