New anti-backlash nuts are ideal for applications that require precise positioning as they eliminate the minimal backlash between the lead screw and nut interface on external linear actuators.
Haydon has added a new series of anti-backlash nuts to its line of linear motion products.
These new anti-backlash nuts are ideal for applications that require precise positioning as they eliminate the minimal backlash between the lead screw and nut interface on Haydon's external linear actuators.
The nuts are manufactured from a proprietary self-lubricating polyacetal that, when combined with the company's precision rolled stainless steel lead screws, provides low drag torque and smooth operation throughout the life of the assembly.
When supplied from the factory with Haydon's standard lubricant these nuts are designed to operate for the life of the motor without relubrication.
They can also be operated without lubrication when combined with PTFE coated screws.
The Haydon "W" series anti-backlash nut assembly uses a patent pending system which preloads two threaded nut halves to eliminate backlash without sacrificing efficiency.
This system optimises load carrying capability and bidirectional axial stiffness while minimising drag torque and system lost motion.
For applications that do not require anti-backlash control, the Haydon N series free wheeling nut optimises system load carrying capability in the industry's most compact package.
Both nut series are available with a thread mount and are easily customisable with a variety of standard or special flange configurations.
These nuts are available in a wide range of diameters and leads that are compatible with Haydon's size 14, 17 and 23 linear actuators.
