Support Units

Support units are special parts for bearings used in a set together with a ball screw. Support units come in various shapes, such as square, round and round 2-surface chamfered. There are also 2 different types—models used at the fixed side and models used at the support side. Support units attach to the fixed side and support side of a screw shaft, enabling the screw shaft to be mounted in the correct position. A bearing integrated into the body of the support unit enables stable shaft rotation. Support units are available with various types of bearings, sizes, shapes and surface treatments. Models for various applications, operating environments and mounting spaces can be selected. Support units can be mounted in equipment as-is, with no need for additional processes or machining.

Advantages of Using Shaft End Support Units

Shaft end support units are assemblies used to securely hold and smoothly rotate the ends of shafts or ball screws, utilizing internal bearings for support.

Easier to assemble than machining blocks yourself.
Saves time and offers factory-standard precision.
Provides good support for both radial and axial loads.
Available in both Fixed Side (rigidly secured) and Floating Side (supported but allows slight movement) types.

General Installation Procedure for Shaft End Support Units

Generally, installing shaft end support units is considered straightforward and easy.

Inspection: Verify that the size and type of the support unit match the shaft and the desired mounting position.
Positioning: Place the support unit in the desired location on the structure.
Securing: Tighten the screws or bolts through the mounting holes of the housing securely.
Shaft Insertion: Insert the shaft end into the bearing bore.
Shaft Locking (if applicable): Some models may have an additional shaft locking mechanism, such as side set screws.

Applications of Shaft End Support Units

Shaft end support units are designed to:

Support shaft ends: Help the shaft rotate stably and reduce vibration.
Secure the shaft axially: Prevent the shaft from moving along its axis (Axial movement).
Self-align: Compensate for minor shaft misalignment to reduce stress on the bearing and other components.
Easy to install: Designed for direct mounting onto machine structures.
