Product Overview
Description
Structure and Features
The Support Unit comes in six types: models EK, FK, EF, and FF, which are standardized for standard-stock Ball Screws provided with 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 rotation performance with high rigidity and accuracy. The Support Unit on the supported side uses a deep-groove ball bearing. The internal bearings of 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 rigidity balance with the Ball Screw, the Support Unit uses an angular bearing (contact angle: 30゜; DF configuration)
with high rigidity and 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 stable rotation performance.

Support Unit Shapes
Square and round shapes are available for the Support Unit to allow 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 assembly can be reduced and the assembly accuracy can be increased.
