THK BNF Ball Screw with Unfinished Shaft Ends
The THK BNF Ball Screw is a precision ball screw with a single nut. It is designed for accurate positioning and smooth linear motion. The nut can be mounted using the bolt holes in its flange.
The BNF Ball Screw has no preload and uses a return-pipe system. Its unfinished shaft ends can be machined to suit the required installation. This makes the ball screw easier to adapt to different machine designs.
THK BNF Ball Screws are available with 16 to 50 mm screw shaft diameters. Basic dynamic load ratings range from 7.4 to 58.2 kN, while basic static load ratings range from 13.9 to 176.4 kN, depending on the model.
