PRT slewing ring bearings


PRT slewing ring bearings are ready-to-install slewing rings for lubrication-free, dry operations. The design is not based on metal rollers or balls but on maintenance-free sliding elements made of the proven tribologically optimised iglidur® materials.
This is in combination with rings made of lightweight anodised aluminium or stainless steel. iglidur® materials can be employed universally and enable use in applications involving high temperatures, moisture or contact with chemicals, as well as in the food industry.

Frequently asked questions about slewing ring systems


Can I restrict the rotation of my slewing ring (PRT)?

Yes, of course. We have a couple of ways in which this can be achieved to any number of degrees. Our Angle limiter kit comprises of the limiter, a limiter stop and pin which all work externally and can be adjusted by yourself. This can be readjusted should the degree of rotation change for your application.

Can I have a slewing ring with multiple ‘home’ positions?

Yes, this is possible. In late 2021 we have released a product which uses a spring plunger to drop in to fixed location points as the slewing ring rotates. Favourites, and standards are 90, 180 and 240 as well as the 0 point.

I need a non-reflective PRT, is black anodising a possibility?

Yes it is and not only that, but we can offer it with black, self-lubricated liners, so the whole product is black in colour.

I’d like a different colour part as the silver stands out. Can you anodise black?

Yes, black along with other colours are available for anodising. There are other options to consider also.
