New range of ball bearings for ball screw applications
For several years R.A. Rodriguez has marketed the Unitec brand of ball screw support bearings designed for high-performance machine tool applications. Now in addition to the high load and exceptional performance capabilities of this needle roller bearing range, the company is introducing a new range of ball bearings to meet more general high-precision ball screw needs.
Sourced from the R.A. Rodriguez German facility, the DRF/DRN double-row ball bearings for screw drives are high-precision components with a contact angle of 60 degrees. They can absorb radial as well as axial forces from both directions and guarantee high running accuracy due to their axial stiffness. The range is therefore suitable for lighter-load applications that call for precise positioning and good repeatability.
The integrated, low-friction seal prevents the ingress of dirt, thereby enhancing reliability and operating life. The bearings are supplied ready-to-fit and lubricated. They may be specified with or without fixing holes and their design ensures swift and easy installation.
Standard precision for the DRF/DRN range is the high accuracy p5/p6 precision class. For lower precision applications a commercial series of the DRF/DRN bearings is also available; this range carries the suffix NP.
Eight types of bearing support units are also available in block or flange design.
Full details of the newly extended range of bearings for ball screw drives from R.A. Rodriguez is contained in a newly published brochure that is available from the company's website.
