NSK Linear motion

The NSK PSS series ball screw is a linear drive component that converts rotation into axial displacement with high efficiency and repeatability. It is used in machine tools, automation equipment and positioning systems where precision and rigidity are critical. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and helps you select the right model for your application.

The designation of the PSS series is read in blocks: PSS identifies the family of precision ball screws; the following numbers indicate the nominal diameter and the lead, and the suffixes define characteristics such as the precision class, the nut type and the overall length. For example, PSS1005N1D0171 corresponds to a screw with a 10 mm diameter and a 5 mm lead, with a single nut and a specific length; PSS1010N1D0221 has a 10 mm diameter and a 10 mm lead. These part numbers allow you to quickly identify the main dimensions and order the exact replacement.

In Argentine industry, NSK PSS series ball screws are used in machining centers, CNC lathes, grinding machines, coordinate measuring machines, laser cutting equipment and industrial automation systems. They also appear in robotics, manipulators and high-accuracy positioning tables. Their ability to support high axial loads with low friction makes them suitable for intensive duty cycles and repetitive movements.

To select the right screw, take into account the axial load, rotation speed, required precision and environmental conditions. Proper lubrication and sealing against contaminants are key to service life. Assembly requires precisely aligning the screw with the guide and the nut, and controlling axial play according to the application. The PSS series supports configurations with a single or double nut, and different precision classes to suit each need.

NSK PSS series ball screws can be interchanged with equivalent products from other brands, but dimensional and functional compatibility must be verified case by case. If you have a part number from another brand or an unidentified part, at MR Accesorios Industriales we tell you the compatible alternative. We work with the leading brands on the market and advise you so that the replacement does not affect your equipment's performance.

If you need an NSK PSS series ball screw, message us on WhatsApp with the part number or the dimensions you require. At MR Accesorios Industriales we quote it promptly and support you in the selection. With more than 80 years in the business, we are your partner for linear motion and power transmission in Buenos Aires, Argentina.

The NSK MCM series linear actuator is a precision motorized component that converts rotary motion into controlled linear displacement. It is used in applications that require exact positioning, regulated speed and reliable repetition, such as coordinate tables, manipulators and testing systems. MR Accesorios Industriales sells this series with technical advice so you can choose the right model for your stroke, load and precision needs.

The MCM series designation is structured with several numeric and letter blocks that identify the size, configuration and options of the actuator. For example, MCM03005H05K00 corresponds to an actuator of the MCM series with a ball screw, while MCM03010H10K00 varies in stroke length and other parameters. The H and K suffixes indicate specific construction features, such as the guide type or the measuring system. To correctly interpret each part number, it is essential to consult NSK's technical documentation or contact MR so we can advise you.

These actuators are used in industries such as automotive, consumer electronics, pharmaceutical and metalworking. In Argentina, they are common in assembly machines, visual inspection equipment, dosing systems and test benches. Their ability to operate with high repeatability and controlled speeds makes them suitable for processes where precision is critical. MR Accesorios Industriales sells them to supply both integrators and end users who need reliable linear motion components.

When selecting an MCM actuator, take into account the load to be moved, the required stroke, the speed and the positioning precision. Mounting must ensure correct alignment with the guide and the coupling to the motor; misalignment can generate vibrations and premature wear. Proper lubrication and sealing against contaminants extend service life. If the actuator includes a ball screw, verify the preload and axial play according to the application. For environments with dust or humidity, consider the available protection options.

NSK MCM series linear actuators may have equivalents in other automation component brands, but interchangeability is not direct: mounting dimensions, stroke, load capacity and screw type vary between manufacturers. If you have another brand's part number or an unidentified part, at MR we will indicate the compatible alternative. It is always advisable to validate the technical specifications before replacing an actuator to ensure system performance.

To request a quote for the NSK MCM series linear actuator you need, send us the full part number on WhatsApp. At MR Accesorios Industriales we will quote it for you shortly and provide the technical advice so that the integration is successful. We can also help you if you are looking for a specific variant within the MCM series.

The NSK SA series ball screw is a linear transmission component that converts rotation into axial displacement with high efficiency and repeatability. It is used in machine tools, machining centers, automation equipment and positioning systems that demand sustained precision. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the right configuration for your application.

The SA series designation is read in blocks: the initial W indicates the screw type, the number that follows is the nominal diameter, and the letters SA identify the series. The suffixes provide key data: 2Z or 4Z indicate the number of ball circuits, C5 or C6 the accuracy grade, and Z5 or Z6 the axial clearance. For example, W2802SA-2Z-C5Z5 has a 28 mm diameter, two circuits, C5 accuracy and Z5 clearance; W2803SA-4Z-C5Z6 combines four circuits with C6 accuracy and Z6 clearance.

In Argentine industry, SA screws are used in milling machines, CNC lathes, grinding machines, coordinate measuring machines, Cartesian robots and testing equipment. They also appear in precision presses, bottling lines and laser or plasma cutting systems. Their ability to withstand high axial loads with low friction makes them suitable for continuous and demanding cycles.

To select the right screw, consider the axial load, rotation speed, stroke length and required accuracy. The Z sealing protects against contaminants; in environments with chips or dust, additional seals should be evaluated. Grease or oil lubrication must follow the manufacturer's recommendation, and alignment between screw and guides is critical to avoid premature wear. Mounting of the supports and tightening of the nut also affect performance.

NSK SA series screws are interchangeable with other brands of ball screws with equivalent performance, but interchangeability depends on mounting dimensions, lead, diameter and nut type. If you have another brand's part number or an unidentified part, send us the data and we will indicate the compatible alternative. MR Accesorios Industriales sells the NSK line and can quote you the exact model you need.

To move forward with your inquiry, send the full part number by WhatsApp to MR Accesorios Industriales. We will quote you promptly and help you define the configuration that best suits your equipment. If you are looking for a variant that is not listed, write to us with the model or dimensions and we will handle it.
