Nuts and flanges
Choosing the correct nut for the lead screw, need not be a headache. We have standard nut designs to suit most applications and when you want a nut to incorporate some special form of attachment or load we can also help.
Primarily we use Delrin as our base material for the plastic nuts. Delrin is an acetal resin engineering plastic and is often used as a metal substitute. Delrin is lightweight, has a low coefficient of friction, is extremely wear-resistant and capable of operating in temperatures in excess of 90 degrees Celsius (approx 200 degrees Fahrenheit). Other plastic materials we use are: polyoxymethylene (POM), acetal resin, polytrioxane and polyformaldehyde. Bronze nuts are normally machined from SAE660 bronze but we have also machined in aluminium bronze hybrids for certain applications.
One new nut design utilises a revolutionary cam collar, which will eliminate the backlash, maintain a high axial stiffness and simultaneously reduce drag friction. Other designs enable lighter loads (up to 4.5kg) smooth movement and low drag torque for very little cost. Some nut designs utilise the latest technology in injection moulding techniques to produce the precision form complete with an integral three holed attachment flange for ease of connection to the application. This particular nut has an external spring and collar arrangement which creates the axial preload to eliminate the backlash when on the screw. (Please also note that our antibacklash nut designs compliment the complete range of lead screws and in some cases can be tapped to run on ball screw threads.)
If you require further technical information, please do not hesitate to contact our sales engineers who will be more than happy to help you with your selection.
Plain thread mount leadnuts
Our standard Plain leadnuts are available in several thread forms.
STANDARD FEATURES INCLUDE:
- Turcite-X plastic nuts provide low friction for high efficiency movement.
- Lead nuts tapped in ACME, Unified National V, Metric V, and Metric Acme thread forms.
- Separate mounting flanges can be assembled to our Plain lead nuts without integral flanges.
Anti-Backlash Leadnuts (AB)
Our standard Anti-Backlash lead nuts are available in several thread forms. The anti-backlash feature compensates for clearance or wear between the leadscrew and nut when reversing the direction of movement. Abssac offers standard leadnut and lead nut assemblies in many designs and thread forms. However, we also welcome inquiries for special nut designs. Lead nuts are available in other materials upon request.
Standard Features:
- Turcite™ X polymer nuts in Plain or Anti-Backlash design.
- Lead nuts are available in ACME, Unified National V, Metric V, and Trapezoidal (Metric Acme) thread forms.
- Optional Flanges can be assembled to our Plain or Anti-Backlash nuts for additional mounting options.
