Horizontal Shaft Support SHF

Horizontal Shaft Support SHF
ISUTAMI SHF horizontal shaft support, also known as the SHF horizontal shaft support block, is a metric assembly for end or intermittent support, to position the shaft on which the bushing bearing slides smoothly. The linear shaft uses the shaft mount, so it is lightly loaded and does not require a slight shaft deflection. The shafts are usually mounted in pairs, allowing the carriage or table (with mounted bearings or bushings) to slide back and forth. The shaft must be aligned parallel to each other or the carriage will not run smoothly.

Horizontal Shaft Support SHF Features

Unlike the shaft support rails, the SHF horizontal shaft support do not allow the open ball bushing bearings to pass longitudinally. The shaft support block can clamp the shaft without the use of bolts to maintain the position of the shaft. It is recommended to shimming high-precision applications to eliminate the effects of variations in the surface of the pedestal or manufacturing tolerances between supports.

The SHF horizontal shaft support is a steel one with a weight range of 13-890g. There are flanges on both sides of the bottom of the shaft support, and each has a screw hole with a diameter (S) ranging from 5.5 to 14 mm. The matching mounting screws are M5-M12 screws. The series of shaft bearings use side clamping to secure the linear shaft. And the size of the locking screws is M4-M12.

The overall height (F) of the SHF horizontal shaft support ranges from 24-83 mm, the width (W) ranges from 43 to 122 mm, and the length (L) ranges from 10-50 mm. The diameter of the linear shaft matched with the SHF shaft support ranges from 3 to 50 mm.

For heavy-duty linear bearing units and long linear axes, ISUTAMI recommends the use of axle supports to eliminate shaft bending. For these applications, continuous or at least partial support of the shaft is necessary.
