Short product lead time
Most standardized bearing products are
available in stock. In stock items can be
shipped within 2 working days with
reception of purchase order.
Flexible bearing choice
For each model, users can choose
bearings between various accuracy
grades and origins based on precision
class requirements and budget.
Made for harsh environments
Each support unit is supplied with grease
already applied and is equipped with
seals, which significantly extends the
bearing lubrication interval.
DESCRIPTION
The ball screw support unit, also known as the ball screw
bearing housing or bearing housing, is typically installed
at both ends of the ball screw to provide axial and radial
support for its rotational motion. In addition to ball
screws, it can also be used for other types of lead
screws, such as trapezoidal screws, or for applications
that require support for rotational motion, such as
splines, shafts, and other similar components.
Depending on the application, support units can be
classified into two main types: fixed end units and
support end units. Fixed end units provides both axial
and radial support for the ball screw, while the support
end units only provide radial support to compensate for
axial expansion and contraction of the lead screw during
operation due to factors like temperature rise.

PRODUCT LINEUP AND CLASSIFICATION:
Classification by application:
➢ Fixed end units provides both axial and radial support for the ball screw.
➢ Support end units only provide radial support to compensate for axial expansion and contraction of the ball
screw during operation due to factors like temperature rise.
➢ For general application, use fixed end units and support end units in pair for each ball screw.
➢ For application with high loads (e.g., heavy milling machines), use heavy duty series fixed end units on both
end of ball screw. Please consult with HZMotion technical support for this type of application.
Classification: Fixed End Support Unit Support End Support Unit
Load Type: Radial & Axial Radial
Typical bearing type: Angular contact bearing pair Deep groove ball bearing

The maximum axial load refers to the greatest axial load that the bearing housing can withstand. At this load, the structural safety of
the bearing housing is fully ensured. Engineering practice shows that when the average axial load on the bearing housing is
approximately 20% of its maximum axial load, its service life can be fully guaranteed.
** The axial load capacity increases when using fixed end supports on both end of lead screw.
Classification by installed bearing capability:
➢ Use the table below as quick reference to select support units based on axial load and lead screw diameter.

DIMENSIONAL CHARACTERISTICS:
Comparison between low to medium load capacity series:
➢ The EK/AK/LK series bearing housings have similar installation characteristics, with the main dimensional
differences between them being in the axial projection plane, as shown in the figure below:
Note1： Using the lead screw rotation center as the reference point for dimensions, the LK series occupies less bottom space
compared to the AK series.
Note2: Compared to the AK and LK series, the EK series has a lower shoulder height on the mounting tab.
Note3: The AK and LK series feature countersunk holes for internal hexagon bolt heads at the bolt mounting positions, while
only partial of EK series (EK06/EK08) have this feature.
➢ The main difference between the three series (EK/AK/LK) and the BK series is that the BK series uses four
bolts for installation, achieving a narrower mounting shoulder size in the axial projection plane.
Top view Front view Isometric view:
Note1： The BK series has a narrower mounting shoulder width compared to other block style bearing supports.
Comparison between high load capacity series:
➢ The axial mounting bearing housing (WBK/FBSA/MBK) are primarily used in heavy-load scenarios. Each
bearing housing is designed with its corresponding bearing and application-specific features. Please
refer to specific drawings in this technical manual to obtain accurate dimension parameters.

HOW TO ORDER / PART NUMBER LOOKUP:
For low to middle load capacity series:
* Represents actual shaft diameter except following models: EF08, LF08, LF10, AF10, AF12, EF10, EF12, BF10, BF12, FF10 & FF12.
Please refer to specific drawings in this technical manual to obtain accurate dimension parameters.
For high-load capacity series:
* Represents actual shaft diameter in mm. FBSA series uses 3-digit code to represent shaft diameter. The corresponding shaft
diameter for each code is listed and marked with “FBSA Only”.
