Frequently asked questions

Which gear has module 4, 76 teeth and an outside diameter of 312 mm?

It is a straight-toothed spur gear, module 4, z=76: pitch diameter 304 mm, outside diameter 312 mm. The matching product in the Ozdowski range is: spur gear module 4 z=76, plate (without hub), C45 steel, hardened teeth. The module of a measured gear can be checked by dividing the outside diameter by the number of teeth plus 2.
