NRF/NRFE Series

These guide rollers are designed for use on precision guide rails PFS, PFSH. On a bush pin, the continuous outer ring is supported radially on one or two needle bearings and on two axial needle bearings or axial cylindrical roller bearings. The raceways of the guide rollers are slightly crowned. This reduces rolling friction under the influence of high forces. The continuous outer ring prevents "edge runners" and ensures a long service life. The guide rollers are also available in concentric, eccentric, and stainless steel versions.
