Approximate travel available for a particular slide guide can be determined by subtracting the carriage length L1 from the rail length chosen.

The corners (r) of the reference planes should be finished with undercuts as shown in Figure 3. The recommended heights of the shoulders of the mounting planes are as shown in the table. To attain high accuracy, it is recommended to finish the mounting planes of the bed and table to an accuracy the same as or better than that of the guide rail and block.

Recommended Tightening Torques: The recommended tightening torque for the mounting bolts (hex socket head bolts) are shown in Figure 4.

To install a BSG Guide (Fig. 4), confirm the reference planes as shown in Figure 1, then let the reference planes of the bed and table make close contact with the reference planes of the object and fix them. When using two guide rails, fix the reference slide in a state in which it is closely contacted with the reference plane. Fix the adjustment side after adjusting the traveling state with either the guide rails or the block in a free state.
