SNAB Anti-Backlash Nuts

SNAB Anti-Backlash Nuts

Thomson's SNAB thread-mount style design has the greatest design flexibility allowing anti-backlash assemblies through 1 inch diameters. Often imitated, this design offers extreme simplicity. Slightly less stiff than the XC series lead screw nuts, but still providing zero backlash up to the preload weight in the catalog specifications.  All SNABs are made from our internally lubricated Acetal providing excellent lubricity and very low wear.
