Precision Ringslide RPM 3
Play-free pre-loaded circular movement, high running accuracy, reliability and a light and smooth motion are the main features of the RPM-frictionless ringslide. The compact size also makes a low construction possible. This simple but innovating design is based on state-ofthe-art technology developed by the specialists of PM - BEARINGS.

Ringslide RPME

RPME ball recirculating units are single row ball bearings for low to medium loads. The units can be used in every orientation. The main body in made of high quality stainless steel 1.4034 and through hardened at 56 /- 2Hrc and precision ground. The special designed return offers extremely smooth running characteristics. For one set you need to order one inner and one outer recirculator.

RPM-2 row Trackrail
RPM rails are 2-row precision tracks providing spacesaving solutions. They are standard manufactured from high quality stainless steel 1.4034, through hardenend 56 /-2Hrc. RPM guides can be mounted directly into the application.

RPMT - Sliding table
RPMT tables are used to attach and preload the recirculating units to the RPM rail. They are made of hardened stainless steel which allow the user to add custom holes easely. The tables include standard countersunk attachment holes for the recirculating units. Tables are precision ground finished.
