Type T - Set of bevel gears, 3 bevel gears, 1 x right-hand, 2 x left-hand pitch

Information
GN 297 bevel-gear wheels are used for angular / T-gears in connection with linear actuators / transfer units and housings. (See GN 298 for examples of use.)
The spiral bevel facilitates both setting the desired clearance and locating the correct position of the bevel gears. Meanwhile, the spiral bevel also greatly reduces noise levels.
Two bevel-gear wheels are required for an angular gear (set sold as Type W), and three for a T-gear (set sold as Type T).
Please note that only bevel gears with different pitches can be paired. The transmission ratio is always 1:1 because bevel gears always have the same number of teeth.
