PM is an independent, family-run Dutch company with over 50 years of experience in manufacturing of precision linear bearings, frictionless slides and positioning systems.

Demanding industries continuously push us to find innovative solutions to our linear bearing systems and crossed roller configuration technologies. This core competence has paved the way for PM to develop its position as an architect of motion systems and integrated solutions.

The combination of our manufacturing knowhow and mechatronic expertise together with customers application specific knowledge is the key in solving complex technological challenges.

Product Lifetime Management

Safeguarding structured development and continuous product support is a core value. To aid in achieving this, PM has adopted a Product Lifetime Management (PLM) system, supported by Siemens NX and Teamcenter. Our mechanical and mechatronic system engineers use the latest in 3D CAD and FEA tools and design revision management is at the heart of it all. In close cooperation with the customer we can therefore quickly and effectively modify existing products or develop entirely new products.

Catalog and custom made

Over time, PM has developed an impressive range of standard catalogue products which are readily available to our customers. The catalogue comprises a wide variety of variants on our crossed roller bearing types as well as circular and recirculating precision bearings.

In addition to this, our standard program also offers motorized stages driven by a variety of types of motors. When these modules are stacked, cost effective stages can be configured. PM offers the service of customization or a complete redesign of our standard products to better suit customers’ specification

Motion system development

For customers with challenging specifications or special needs, PM offers the service of specific motion system development. From conceptual idea to design and production; it can all be taken care of. To ensure our products perform according to specification, the well-known V-model is adopted. System concepts are evaluated and customer specifications are translated to engineering specifications with our in-house developed Multibody Dynamics model. Subsequently sub-systems are designed and validated with the purpose of functioning in synergy when assembled as a whole.

Manufacturing expertise

PM is able to accommodate production on various levels of magnitude: from prototyping or sampling batches to moderate and high volume production. Through integration of production models like Kanban and J-I-T in our ERP system, we remain resilient to market demand fluctuations. Our own production plant allows us full control of manufacturing processes like high precision grinding, milling and material hardening, which ultimately improves the overall product quality.

Vacuum technology

PM has extensive experience in design and manufacturing of HV and UHV chambers and components. Using specific design tools for vacuum applications and our own understanding of materials optimized for vacuum applications, we can offer a complete, cost-effective solution, suited specifically to the customer’s needs.

Cleanroom facilities

To be ready for the requirements of tomorrow’s world, PM has ISO 5 certified cleanroom facilities. In our 1500m2 (15 000 sq. ft.) cleanroom we can assemble, test and package components and systems, ready for cleanroom application at the customer.

Development of computational tools

As an integral part of our R&D-activities, PM continuously develops new computational tools as they are needed in current or future design and qualification efforts. Major benefits of developing these tools in-house are full control and understanding of various model outputs and the assurance of applicability to PM’s specific needs. Many of these models are MATLAB-based. A few examples of tools that have been developed are:

  • Nonlinear bearing stiffness calculator

  • Topology optimization routine

  • Constrained multibody dynamics simulation program

Qualification and testing

A wide range of products requires a wide range of equipment for qualification and testing purposes. On component level our profilers, coordinate measurement machines and optical instruments provide valuable insights, while on system level our dynamic testing equipment allows us to identify machine frequency responses, identify mode shapes and specify operational parameters, even at the customer’s location if desired.

Quality control

PM strives for high product quality, through risk mitigation and process control throughout the entire production chain, from conceptual design to final testing and qualification. Methods such as statistical process control, FMEA, 8D and constant multi-level internal reviews help in maintaining our high standard in product quality.
