FD1010-DLR-T-P4S series high-speed floating displacement bearing description

Floating displacement bearing is an ideal high-speed floating bearing solution when the ultimate operating speed is to be reached but the required load capacity is not the decisive factor. Floating displacement bearings can reach the speed of high-speed angular contact ball bearings, which is twice the speed of ordinary cylindrical roller bearings. Therefore, it is especially suitable for electric spindles. The floating displacement bearing is composed of the outer ring of the ball bearing and the inner ring of the cylindrical roller bearing. Ceramic balls are standard rolling elements. This design ensures that the inner ring can float freely relative to the outer ring during operation. The inner ring is made of Cronidur 30 high-performance bearing steel, which has a higher permissible Hertz contact stress than ordinary bearing steel. The contact between Cronidur 30 and ceramic balls ensures that the inner ring and the rolling elements have sufficient load-bearing capacity. During the assembly process, the bearing clearance must be set according to the operating conditions. The industrial application technology department provides consultation under simulated actual operating conditions.

Floating displacement bearings have the same external dimensions as B70…series bearings or N10…series cylindrical roller bearings, and their sufficient load-bearing capacity and high speed capability provide designers with a new floating bearing layout design. The FD series of floating displacement bearings can be used in existing structures with lower rated load and can easily increase the allowable speed. Provide floating displacement bearings and spindle bearings with seals on both sides (2RSD) or direct lubrication for oil and gas lubrication. Similar to super-precision cylindrical roller bearings, the floating displacement bearing FD bearing series also has a type with a tapered bore inner ring (K). The FD bearing series with radial clearance matching the bearing bore is also provided, which simplifies the arrangement of the bearing on the shaft and allows a variety of bearings to be installed side by side in groups.
