NSK-RHP's linear axis Monocarrier system NSK-RHP's linear axis Monocarrier system can now be used in environments where normal lubricants are not permitted, thanks to the company's K1 lubrication technology, which provides simultaneous sealing and lubrication from one unit. The K1 unit is manufactured from a porous synthetic resin, which is oil impregnated. This avoids any need to re-lubricate and enhances the linear system's long term performance. The Monocarrier system distinquishes itself from other linear systems by integrating the components into a precision, single-axis feed mechanism for easy installation and alignment.
