Gleason-Pfauter spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Gleason-Pfauter spindles and motor spindles: gear hobbing, shaping, Power Skiving and gear grinding machines built in Ludwigsburg (Germany) within the Gleason group.
Gleason-Pfauter, from hobbing to gear grinding
TLDR: Gleason-Pfauter Maschinenfabrik GmbH (Ludwigsburg) is the heir to Hermann Pfauter, founded in Chemnitz in 1900. The Pfauter group joined Gleason Corporation in 1997. The range covers hobbing, shaping, Power Skiving and gear grinding.
Robert Hermann Pfauter invented and patented the gear hobbing process in 1897, and Hermann Pfauter Maschinenfabrik was founded in Chemnitz in 1900. After the 1952 expropriation, the Pfauter family opened a new plant in Ludwigsburg, West Germany. A few milestones cited by Gleason:
- 1975: first numerically controlled hobbing machine, shown at EMO Paris
- 1983: first PE150 CNC
- 1987: first profile grinder
- 1994-1995: takeover of Mikron's gear business in Biel (Switzerland) and launch of the P100 dry-hobbing machine
- 1997: the Pfauter group joins Gleason Corporation
- 2006: Genesis series of hobbing machines
- 2012: complete Power Skiving range
- 2014: GX series of threaded-wheel grinders
- 2015: the Gleason-Hurth division is merged into Gleason-Pfauter
For older machines bearing only the Pfauter name, see also our Pfauter page.
From hob spindles to shaping heads
TLDR: On a 2002 GP 130 S, the hob spindle has a PKP 45 (Bauer) hollow taper, for hobs up to 175 mm in diameter. A 2008 P 1200 S shapes at up to 80 strokes per minute, with a total power of 75 kW.
For example, a Gleason-Pfauter GP 130 S (2002) cuts parts up to 300 mm in diameter, module 4 in steel, with a PKP 45 (Bauer) hollow-taper hob spindle, a 1¼-inch hob arbor, hob diameters up to 175 mm, a 30 mm shift and ±0.25° adjustment. A P 1200 S (2008, gear shaper) is listed with modules from 0.5 to 16 mm, workpiece diameters up to 1,200 mm (1,400 mm without outboard support), up to 80 strokes per minute with the H1 hydraulic head, and 75 kW total power.
On a gear cutting machine, a Gleason-Pfauter spindle defect ends up directly on the teeth: pitch, profile, surface finish. Rotation speeds, spindle power ratings and bearings are not given in these examples: we confirm them in our quote.

Frequently asked questions
Do you repair the hob spindles of Gleason-Pfauter machines?
Yes, we check the bearings, runout, taper and balancing of the Gleason-Pfauter spindle, then overhaul it.
Do you work on P S series gear shapers?
Yes, we handle both the spindle and the shaping head.
What is the difference between Pfauter and Gleason-Pfauter?
Pfauter is the historic name; Gleason-Pfauter has been used since the Pfauter group joined Gleason in 1997. See also our Pfauter and Gleason pages.
What is the average turnaround for a complete overhaul?
Allow around 20 working days in our workshop, depending on the condition of the spindle and parts availability (bearings, seals, specific components).
