Inch Standard Accuracy Ball Screw Features

SRT – Standard Rolled Thread (sometimes referred to as commercial or transport type) ball screws offer the low friction advantage of antifriction screws at lower cost. They are capable of higher speeds and longer predictable life when compared to similar acme type lead screws.

Offered in diameters from 3/8" to 6" and leads from .125" to 1.875" depending on diameter, they are manufactured from the same high quality materials and produced following the same ISO certified procedures as higher precision screws. Most SRT screws are rolled, induction heat treated and black oxide coated. Three sizes are also available in 17-4 PH stainless steel.

SRT screws are offered with OD threaded, non-preloaded ball nuts, with optional mounting flanges and wipers. Some sizes are also available with integral flange nuts and/or with double nuts. Double nuts have a spring loaded adjustable preloading feature for eliminating backlash.

For convenience SRT screws can be supplied completely machined and assembled with nuts, flanges, wipers and EZZE-MOUNTS ready for assembly to your product. Should a standard assembly not fit the application, Nook can machine the screw to your specific design requirements.
