Stand-Up Shaft Support SKW

Stand-Up Shaft Support SKW
ISUTAMI SKW stand-up shaft support, also called SKW linear shaft support block, is an inch assembly for end or intermittent support. It is the machine component that position the shafts where linear bearings slide. The linear shaft using the shaft mount is lightly loaded and does not require a slight shaft deflection. The shafts are commonly installed in pairs, allowing a carriage or table with installed bearings or bushings to slide back and forth. The shafts must be aligned parallel to each other or the carriage will not move smoothly.

Stand-Up Shaft Support SKW Features

Unlike the shaft support rails, the SKW stand-up shaft support do not permit longitudinal passage of open ball bushing bearings. Shaft support blocks enable clamping of shafts, eliminate the need for bolts to maintain shaft position. Shimming is suggested for high precision applications to eliminate the effect of variations in surface of base or manufacturing tolerances between supports.

SKW stand-up shaft support is an aluminum one, has a weight range of 15-716g and is more resistant to corrosion than the steel SK shaft support. There are flanges on both sides of the support bottom, and each has a screw hole with a diameter (S) ranging from 0.156’’ to 0.406’’. The series of shaft blocks use side clamping to secure the linear shaft. There is a gap at the top of the support, which is controlled together with the locking screw to the tension between the support and the linear shaft.

The overall height (F) of the SKW vertical shaft support is 1.063''-4.5'', and the width (W) range is 1.5''-5.5'', and the length (L) range is 0.5''-1.5''. The width error range is ±0.05mm and the height error range is ±0.02mm. The diameter of the linear shaft matched with the SKW shaft support is 0.25''-2''. The SKW series includes 9 specifications from SKW4 to SKW32.
In general, the advantages of using PA shaft supports are as follows:
For easy installing and quick aligning
Precise design with reference edge
More affordable than in-house designs

For heavily loaded linear bearing units or long track lengths, ISUTAMI recommends the use of shaft supports to eliminate shaft bending. For these applications, continuous or at least partial support of the shaft is necessary.
