The NSK PFT series ball screw turns motor rotation into axial movement with minimal friction and high repeatability. It suits machines that must position loads accurately, such as machining centers, measuring systems, actuators and automation axes. MR Industrial Accessories supplies this series to customers across the United States and Latin America.

The PFT code packs the screw diameter and lead into one string, separated by a hyphen. Take PFT 2006-2.5 and PFT 2006-3: the first two digits give the diameter (20) and the next two the lead (06), while the suffix after the hyphen denotes either the number of starts or the nut style, depending on the variant. The same logic applies to PFT 2504-5, PFT 2505-3, PFT 2505-5, PFT 2505-7.5 and PFT 2506-3, where diameter, lead and suffix all shift.

In industrial plants, PFT ball screws show up in CNC milling and machining centers, grinding machines, laser and plasma cutters, coordinate measuring equipment and automation actuators. You will also find them in test benches, manipulators and linear axes that demand repeatability and axial rigidity. Because it is a precision component, the choice depends on the load type, operating speed and the positioning accuracy your equipment needs.

When specifying a ball screw, consider the axial load, critical speed, unsupported length and allowable axial play. During installation, align the screw with the guide, use supports with precision bearings and follow the correct tightening torque for the nut. Lubrication and sealing against contaminants are key to extending the life of the assembly. For vertical applications, add a retention or brake system to keep the load from dropping.

Ball screws from different manufacturers can often be swapped if diameter, lead, length and nut type match, but supports and beds may need modification. If you have a part number from another brand or an unidentified part, MR Industrial Accessories can point you to a compatible alternative.
