Product Description
Introduction

Structure and Features
The Support Unit comes in six types: models EK, FK, EF, and FF, which are standardized for the
standard Ball Screw assembly provided with the finished shaft ends, and models BK and BF, which
are standardized for ball screws in general.
The Support Unit on the fixed side contains a JIS Class 5-compliant angular bearing provided with an
adjusted preload. The miniature type Support Unit models EK/FK 4, 5, 6 and 8, in particular, incorporate
a miniature bearing with a contact angle of 45° developed exclusively for miniature Ball Screws.
This provides stable rotational performance with a high rigidity and an accuracy.
The Support Unit on the supported side uses a deep-groove ball bearing.
The internal bearings of the Support Unit models EK, FK and BK contain an appropriate amount of
lithium soap-group grease that is sealed with a special seal. Thus, these models are capable of operating
over a long period.

Uses the Optimal Bearing
To ensure the rigidity balance with the Ball Screw, the Support Unit uses an angular bearing (contact
angle: 30°; DF configuration) with a high rigidity and a low torque. Miniature Support Unit models EK/
FK 4, 5, 6 and 8 are incorporated with a miniature angular bearing with a contact angle of 45° developed
exclusively for miniature Ball Screws. This bearing has a greater contact angle of 45° and an
increased number of balls with a smaller diameter. The high rigidity and accuracy of the miniature
angular bearing provides the stable rotational performance.

Support Unit Shapes
The square and round shapes are available for the Support Unit to allow the selection according to
the intended use.

Compact and Easy Installation
The Support Unit is compactly designed to accommodate the space in the installation site. As the
bearing is provided with an appropriately adjusted preload, the Support Unit can be assembled with a
Ball Screw unit with no further machining. Accordingly, the required man-hours in the assembly can
be reduced and the assembly accuracy can be increased.
