Gear rack crossover: Atlanta, GAM, Güdel and more
Find the RackPro equivalent for the gear rack you use today. Racks are matched on what engineers specify — module, tooth form, hardness, finish and quality grade — and every cross is confirmed by our engineers before we quote.
Direct equivalent same tooth form, module, hardening and grade in the published catalogs Equivalent — review same rack with a different grade, length or detail Alternative different hardening or helix — engineering review required Made to order not a catalog rack, but we make it: module, material, shape or helix to your requirement
All matches are catalog-based. Before we quote, our engineers confirm mounting holes, section size and the other dimensions critical to your installation.

Competitor series, grades and part numbers are taken from their published catalogs and web pages. Atlanta grades are ATLANTA quality classes; GAM grades are ISO; KHK grades are JIS. In the RackPro code, change the M and the length to suit (for example RP-HR-G-M3-Q6-2000). Don't see your rack? Send us a drawing or part number.
