Our trapezoidal threaded screw with bronze nuts give traversing systems with better efficiency, fluency and quietness compared with couplings with machined screws. Because of low friction coefficient, the amount of heat generated during the movement is limited with resulting smaller nut heating. Nut life is also increased. The nuts we make with length 3xd: HDL, BIG and HAL deserve special attention.
These bronze nuts, thanks to their considerable length, distribute the load over a larger number of holding threads and limit surface contact pressure between screw and nut. This is decisive for long nut life. By using the 3xd long nuts compared with bronze nuts with conventional length (approximately 1.5xd or 2xd), higher loads can be born for equal traversing speed.
Where it is not desired to lubrificate trapezoidal screws, self-lubrificating plastic nuts are recommended. It is not possible to couple plastic nuts with screws made by machining. |
