When a machine needs rotary motor input turned into accurate linear travel, the NSK RMA series ball screw is one of the options maintenance and purchasing teams look at. It fits machine tools, machining centers, measuring systems and automation equipment where rigidity and repeatable positioning matter. MR Industrial Accessories LLC supplies this line to customers throughout the United States and in several Latin American countries.

Reading an RMA code is a matter of breaking it into blocks. The letters name the family; the digits that follow give nominal diameter and lead; the C and S suffixes tell you the recirculation type and how the screw is configured. Two examples, RMA0601C7S-160 and RMA0802C7S-280, show how diameter, lead and length change from one reference to another. The block after the hyphen normally refers to overall length or travel. NSK's technical documentation is the right place to confirm how a specific code is interpreted.

Typical applications include CNC milling machines, precision lathes, grinding machines, laser cutting equipment and inspection stations, as well as manipulators, servo presses and other high-accuracy positioning systems. Because the design carries substantial axial load while keeping friction low, it suits continuous, demanding duty cycles.

Selection should start from axial load, critical speed, the rigidity the application calls for and the mounting arrangement. Sealing and lubrication have a direct effect on service life, and in areas exposed to chips or dust extra protection is worth considering. Careful alignment between the ball screw and the linear guide prevents parasitic stresses. Axial play is set according to the precision required, and grease or oil can be used depending on the application.

Interchange with other brands of comparable performance is possible, but true equivalence depends on dimensions, lead, preload and precision class. Matching diameter and length alone is not sufficient; load capacity and nut type also need to be checked. If you are working from another brand's part number or from an unidentified component, send us the details and we will point you to a compatible alternative.
