Mädler drive components identification and part numbers
Mädler GmbH supplies precision mechanical drive parts identified by an 8-digit part numbering structure: initial digits define product families while suffix numbers specify teeth, bore and tolerances.
When replacing worn machinery components with missing tags, physical dimensions such as tooth count, module, chain pitch or shaft diameter allow verified cross-referencing against factory documentation.
Our technical sourcing specialists match field measurements with Mädler CAD models and factory engineering tables to confirm drop-in interchangeability.
Precision spur gears, helical gearing and machined racks
Mädler spur and helical gears span metric modules 0.5 to 8.0 mm in C45 carbon steel, 1.4305 stainless steel, brass and polyacetal POM for quiet running.
Options include hubbed gears for finish machining and plate wheels, with optional tooth induction hardening up to 55 HRC for elevated wear resistance under cyclic loads.
Ground gear racks up to 2000 mm support seamless end-to-end gantry assembly across linear automation axes and CNC portal machinery.
Bevel gears, spiral Gleason sets and worm gear drives
For 90-degree angular transmissions, Mädler produces straight and spiral Gleason bevel gear sets delivering smooth, quiet meshing and high torque transfer.
Gears are supplied in matched lapped sets across ratios up to 4:1. Accurate case-hardening and ground bearing surfaces ensure precise gear mesh and extended operational life.
Worm drive assemblies combine case-hardened steel worms with centrifugally cast CuSn12Ni bronze wheels for low friction and anti-scuffing durability.

Belts are manufactured from durable polyurethane with steel or Kevlar cord reinforcement, and chloroprene neoprene with fiberglass tensile cords in endless or open-length rolls.
Positive synchronous engagement eliminates belt slippage, maintaining exact angular positioning and synchronized velocity ratios.
Flexible jaw couplings, metal bellows and torque limiters
Mädler couplings compensate for axial, radial and angular misalignments while attenuating torsional vibrations to protect drive motor bearings.
Jaw couplings feature 92° and 98° Shore A elastomer inserts to adjust dynamic damping and torsional stiffness to match equipment requirements.
Stainless steel bellows couplings deliver zero backlash for high-speed servo axes, while mechanical friction torque limiters protect against machine jams.
