Splines & mangenoter

William Petersen specializes in manufacturing both internal and external splines as well as keyways using advanced production methods such as hobbing or broaching.

These methods ensure precision and durability in the production of complex tooth profiles and keyways that meet even the most demanding industrial needs.

We have an extensive range of modules in accordance with DIN 5480/5482 standards, ranging from 0.8 to 8.0. This allows us to produce splines and keyways in various sizes and specifications to fit your specific needs and requirements.

The gearing is carried out in accordance with international standards such as DIN, BS, SIS, or to customer specifications and requirements.

Custom-made splines and keyways

We can also manufacture custom-made broaching tools for machining internal splines and keyways. This ensures that even the most complex tooth profiles can be produced with high precision and quality.

With a maximum length of spline shafts up to 5000 mm, we are able to meet the needs for long and complex components as well.

CTA: Custom-made Product

Do you need a custom-made product?

Our focus is not on producing large series of standard products - instead, we help companies that need a custom-made product for their specific product or machine.

We have our own raw material warehouse, but we can also produce your turned parts if there is a need for something completely unique. We always make sure to first identify the core of your specific needs so that we can find the best solution and help you move forward with your project as quickly as possible.
