SLIDE WAY SLIDE WAY Figure G-3 Structure of NV type Figure G-4 Structure of SV type The NB slide way is a non-recirculating linear motion bearing utilizing precision rollers. It is used primarily in optical and measurement equipment where high precision movement is required. STRUCTURE AND ADVANTAGES The NB slide way NV type comprises precisely ground rails and R-retainers with built-in STUDROLLERs and precision rollers. The rails have been optimally designed so that the STUDROLLERs move smoothly, and the STUDROLLERs and precision rollers incorporated in the R-retainers enable slip-free...

The accuracy of the slide way is represented as parallelism measured across the full length with a method shown in Figure G-6. It is classified as high (blank), precision (P), or ultra precision (UP). Special accuracies can also be accommodated. Please contact NB for details. Figure G-5 Parallelism Figure G-6 Accuracy Measurement Method rail length (L) mm Ultra Preclslon grade is available from size 1 to size 9. RATED LIFE The life of the slide way and the slide table is calculated with the following equations: Rated Life Life Time L: rated life (km) \r. temperature coefficient fw: applied...

Please contact NB for a non-standard stroke length for the NV type. When the stroke of SV type or SVW type is changed, the stroke length must be determined and the load rating should be re-estimated as follows. Stroke of SV type, SVW type When the slide way moves along the rail, the cage moves half the distance traveled by the slide way in the same direction. Therefore, although the work may be fixed on the table, the distance between the load center and the cage center will change. To achieve stable accuracy, determine the stroke and the length of the rail as follows. When the stroke is...

INSTALLATION PROCEDURE OF SV TYPE Installation Procedure ( 1 ) Remove burrs, scratches, and dust from the rail-mounting surface of the bed and the table, be careful to prevent contamination during ( 2 ) Apply low-viscosity oil to contact surfaces. Attach rails©-© by tightening screws with the recommended torque (Table G-4). (Figure ( 3 ) Temporarily attach rail © on the adjustment ( 4 ) Remove end pieces on one end. Carefully insert roller cages between rails. (Figure ( 6 ) Move the table slowly to each stroke end to position roller cages at the center of the rails. ( 7 ) Set the dial...

SLIDE TABLE The NB slide table is a precision table equipped with a slide way. Its high-precision and low-friction characteristics make it well suited for use in electronics automatic-assembly machines, optical The NB slide table consists of a slide way sandwiched between an accurately machined table and a bed. Stoppers are provided inside the table. High Accuracy The mounting surfaces of the table and bed are precision finished to ensure high precision linear motion, resulting in a high performance slide way. Its non-recirculating mechanism provides stable motion at from low to high...
