Expertise for combined motion
Previously, combinations of needle roller bearings and linear ball bearings were used to support rotating and simultaneously oscillating ink distribution rolls. These designs are relatively costly and require large design envelopes, often not achieving the desired load carrying capacity.
Until recently, needle roller and cylindrical roller bearing solutions were used only within very limited operating parameters. The Schaeffler Group was able to make significant progress here by performing intensive running tests at our in-house test facility. We were able to demonstrate that machined needle and cylindrical roller bearings can be used in a much wider range of applications.
The advantages of these bearing series can now also be used for extreme combined rotary and linear motion. These include the low radial section height and also the excellent availability of cost-effective standard bearings.
Machined needle and cylindrical roller bearings are available with or without seals for oil or grease lubrication.
