Custom worm gear sets
Custom worm gear sets are produced in various designs and materials according to customer specifications.
FMP offers custom gear sets with axial distances from 17 to 210 mm and a maximum worm wheel diameter of 300 mm. If necessary, FMP calculates the tooth profile data, defines the material and surface treatment, and provides consultation on lubrication and torque loads.
FMP has many years of experience in manufacturing worm gear sets, which means that our customers rely mainly on existing gear cutting tools, especially when dealing with short delivery times and small unit quantities. Therefore, the procedure must be checked on a case-by-case basis. To this end, you can contact us personally or use the request form.
