High load capacity ball screw support bearings "TAF-X Series" to market
The Company, in the industrial machinery sector, so far, including the bearing "TAF" series for ball screw support, developed a high-performance bearings, such as its own highly thin-walled bearings and spherical bearing, has been market deployment.
Now, Nachi Fujikoshi, as the line-up strengthening of industrial machinery bearings, plus enhanced further load capacity in the "TAF series," "TAF-X Series", keep up with the performance of industrial machinery.
Market needs
Received the performance of the industrial machinery, in the industrial machinery bearings has expanded the high load and high speed corresponding needs. In particular, in the injection molding machine, there is no companion to the electric of the driving method, for the bearings supporting the ball screw, long life, there is an increasing miniaturization, and high speed of the request.
Features
Longer life: By maximizing the contact angle expansion and steel balls of steel ball and the raceway surface, the axial direction ? 1 increase the load rating. Realize the conventional product ratio of about 1.5 times longer life.
Miniaturization: By the optimal design of the track, axial limit load ? 2 a Compared with the conventional product, expanding about 10 percent. During assembly of the machine, by reducing a combination of such thrust bearing required previously, it enables the downsizing of the bearing periphery.
Faster: By pre-conditioning of the optimization and the preload of the track surface, about 15% reduction in the conventional product ratio of the torque.
This by the permissible speed is improved by about 25% than the conventional product, it corresponds to the speed.
Axial direction: Parallel direction with respect to the axis of rotation of the bearing. A load of this direction that the axial load.
Axial limit load: Contact ellipse of when you load an axial load and the steel ball and the track is moved to the track shoulder, to the maximum of the axial load the contact ellipse does not protrude from the track surface.
