In NSK, every linear guide assembly, the mounting bolt holes are processed after heat treatment using a precision machining center; therefore, the bolt hole pitch accuracy is as good as the positioning accuracy of the machine, which is considered very good. When tightening the bolts, be sure to start at one end and work in order to the other end. If the bolts are tightened at the middle first, it tends to leave the linear bearing rails curved. If you suspect this has happened, loosen the bolts and start again. The rail that has been tightened can now be used as a reference rail. Using a vernier calipers or other accurate tool, measure the distance between the two linear bearing rails, and adjust each end until they are the same. Tighten a bolt snugly at each end of the rail. Move the table to one end of the linear bearing rails, and start tightening the adjusting rail bolt sequentially to the specified torque while checking excessive friction of table movement. Continue moving the table down the rail tightening each adjacent bolt until they have all been tightened. |

Maintenance- free operation with K1 Lubrication Units is standard on the ball screw and linear guide. Unit comes ready for you to install the motor assembly of your choice. Simply aim and bolt the module in place- it is already aligned. |
Here are but some of the NSK Linear Guide features: High Accuracy: The lateral reference surface and linear bearing ball grooves are ground simultaneously for high accuracy and extended life. Ease of Installation: Mounting of rails is simplified due to their excellent linearity and minimum bolt-hole pitch error. Interchangeability in the Series: Linear bearing rails and linear slides do not have to be purchased as a set, reducing replacement costs. Standardization is made much easier. High Resistance Against Impact Load: Under normal operation, downward loads are carried by the upper two rows of balls. The Gothic arch design allows for vertical shock loads carried by the upper and lower two rows of balls. |
