Slewing Bearings

FRUSCA Slewing Bearings (also named Antifriction Bearing, Slew Ring) are mechanical components made of two Drilled Rings (one Inner and one Outer Ring), a gear where needed on one of two, and an internal Rolling System to stand simultaneously Axial and Radial Loads, Tilting Moments, also of considerable values. The Fixing Holes and the simple Manufacturing Shape of the Slew Bearings, permit an easy Mounting and a sensible Cost Reduction for the Manufacturing of the companion Structures. FRUSCA SRL technically supports its Customer in developing of Standard Slew Bearings from catalogues, Special and Made on drawing, Without Gear, External Gear, Internal Gear, from diameter 150 mm to 6200 mm, in different manufacturing shapes from Module 2. FRUSCA Slewing Bearings, depending on the constructive shape, have specific application destinations. FRUSCA Slewing Bearings has a limit speed. Beyond this limit are not considered because they affect the life of the same. The Materials, Treatements and type of Clearance of FRUSCA Slewing Bearings are on various classifications; chosen and used according to use of them. On request FRUSCA provides a Life Time Calculation of any Slewing Bearings.
