The story matters beyond a single machine. It shows what becomes possible when sound original engineering meets disciplined maintenance and expert service: equipment that runs reliably long past its expected life. In an industry where every hour of unplanned downtime is lost production, that reliability is what protects output.

We carried out the work during a scheduled shutdown, with one goal - restore the mechanical integrity of the drive. Our engineers:

Replaced all spherical roller bearings on the high-speed and intermediate shafts

Installed a new high-speed shaft (pinion) housing and realigned the shafts to specification

Verified tooth contact, backlash, axial displacement, and shaft positioning

Inspected the lubrication system, seals, and structural components

After 70 years under the heavy, variable loads of a working ball mill, the gearing told its own story: tooth contact remained correct, with only localized pitting on the low-speed gear set - well within tolerance for equipment of this age.

A fit problem, solved by engineering - not by force

Fitting the new housing surfaced a challenge: its mounting holes did not match the original 1950s pattern. Rather than force the fit and risk the alignment, our team machined the housing to the historic foundation geometry. That preserved both shaft alignment and the rigidity of the whole assembly.

Work like this depends on respecting the machine's original tolerances and choosing the right measurement methods. It is the core of a professional gearbox overhaul - and the reason a 70-year-old unit can return to service performing like it should.

Post-assembly measurements confirmed the gear unit meets every requirement for continued operation, with all clearances and axial settings within factory norms. We also used the shutdown to prepare the unit for vibration monitoring - the foundation of a Condition-Based Maintenance (CBM) strategy that catches wear before it becomes a failure.

Seventy years after it left the factory, the SYMETRO™ TS 1250 still transmits more than 1,250 HP. That is what initial engineering, material quality, and service competence add up to over time.

A 1956 gear unit still running in 2026 is not lucky. It is designed to last, supported by the right service at the right moments. If you operate aging gear units - MAAG or otherwise - the same approach can extend their service life, reduce downtime risk, and prepare them for condition-based maintenance.

Few machines in heavy industry run for 70 years without interruption. One of them is a SYMETRO™ TS 1250 gear unit, built by MAAG Gear in 1956. It still drives a ball mill at the Heidelberg Materials cement plant in Picton, Ontario, Canada - and in early 2026, our engineers completed a full overhaul to keep it in service.

Webinar: Cement plant maintenance

The gearbox industry is navigating a period of significant change. Customers face increasingly complex technical demands, supply chain pressures, and a growing need for partners who combine deep product knowledge with long-term reliability. It is against this backdrop that MAAG Gear has made a deliberate choice: to strengthen its commercial leadership with someone who has lived these challenges firsthand.



"This appointment is both an honour and an exciting opportunity. The gearbox industry is evolving rapidly, and our customers face increasingly complex demands. My goal is to build a commercial organisation that responds to those challenges with expertise, consistency, and a genuine partnership mindset. I look forward to working with our international teams to shape a future defined by collaboration, innovation, and performance."

 - Guillaume Luck,
Chief Commercial Officer

Guillaume's path to this role is anything but conventional. It began on the shop floor - working with CNC machines and later as a field service technician - before evolving through sales management, general management, and international product line leadership. Along the way, he returned to education at an international business school in Paris, adding strategic and commercial depth to an already grounded technical foundation. That combination of experience gives Guillaume a perspective that is both practical and forward-
looking - precisely what MAAG Gear needs at this stage of its growth.


"Guillaume' s appointment is not just about filling a role - it's a signal of where we're headed. We are entering a new phase in our commercial strategy, including a reorganisation of the Commercial Office aimed at building a more efficient structure and further strengthening customer satisfaction. Guillaume has the industry knowledge, the leadership qualities, and the values to help us execute this vision - and I am confident that together we will continue to reinforce MAAG Gear's position as a trusted leader in the industry." 

Those who know Guillaume well will tell you that the same principles that define his leadership also define how he approaches sport. As a committed triathlete and Ironman competitor, he has learned that sustainable performance - whether in racing or in business - is built on discipline, resilience, and the ability to stay focused when conditions get difficult. It is a philosophy he brings directly into his work: developing people, building trust, and creating organisations that perform not just in the short term, but consistently, over time.


With Guillaume on board, MAAG Gear looks ahead with confidence - to stronger customer relationships, a more agile commercial structure, and a team ready to meet the demands of an evolving industry.

MAA Gear is entering a new phase in its commercial development - and Guillaume Luck will lead the way. With 18 years of experience in the gearbox industry and a career built from the ground up, Guillaume brings to the role something rare: a leader who understands the business from every angle, from the shop floor to the boardroom.

MAAG Gear at Semtec 2026 | Cement Industry Event in Brazil

When it comes to cement production, reliability is not just a performance metric — it is the foundation of continuous operations, efficiency, and long-term value.

This is exactly what has been demonstrated over the past two decades at the Ste. Genevieve plant in Missouri, one of the largest and most advanced cement facilities in the world.

Back in the mid-2000s, the ambition behind the Ste. Genevieve project was clear: to set new benchmarks in capacity and operational excellence. From the very beginning, the plant required drive solutions capable of handling extreme loads, high torque, and continuous production cycles.

This is where MAAG Gear’s WPV gear units came into play.

Installed in 2007 to power the plant’s vertical roller mills, these units were designed to meet the demanding requirements of large-scale cement production — ensuring stability, efficiency, and long-term reliability from day one.

Over the years, the WPV gear units have proven their value in one of the most challenging industrial environments.

Their three-stage planetary design, optimized load distribution, and robust construction have enabled:

consistent uptime under heavy operating conditions

efficient torque transmission for large grinding applications

reduced mechanical stress and maintenance needs

In an industry where downtime is not an option, these features translate directly into operational continuity and peace of mind for plant operators.

More than 16 years later, the results speak for themselves.

The WPV gear units at Ste. Genevieve have delivered continuous performance, supporting high production volumes while maintaining efficiency and durability. Their long service life highlights the importance of engineering solutions that are not only powerful, but also built to last.

In December 2025, a new WPV gear unit was commissioned at the plant — fully interchangeable with the original units installed nearly two decades earlier.

This compatibility is more than a technical detail:it reflects a design philosophy focused on long-term value, flexibility, and future-proofing.

Behind this success lies a strong collaboration between MAAG Gear and Amrize (formerly Holcim US). By combining engineering expertise with real operational feedback, it has been possible to develop solutions that truly respond to industry needs.

This case is a clear example of how innovation and partnership can generate lasting impact in the cement sector.

We are proud to share that this story has been featured in the April 2026 issue of 

, one of the leading technical publications for the global cement industry, known for its in-depth analysis and case studies across the entire production chain.
