Features: "Modulus" is the ratio of two teeth adjacent to the same side of the teeth between the tooth profile and the pitch t of the pi π m (modulus) = t (pitch) / π (3.14) Tip diameter D = number of teeth Z +2 * modulus M Gear pitch = 4.71 * modulus M Gear depth =3.375 * modulus M ProductSiteLaunchDate : 2021-09-10T05:30:39.694Z UnitCount : 1 UnspscCode : 26111500
