●End Support Detailed Introduction

1.BK End Support Unit:

The BK end support unit is designed to support the fixed end of the ball screw. It consists of a bearing housing and a bearing block. The bearing housing is typically made of cast iron or aluminum alloy, providing a sturdy base for the ball screw assembly. The bearing block, on the other hand, houses the angular contact bearings that support the ball screw shaft. The BK end support unit ensures axial rigidity and prevents axial movement of the ball screw.

2.BF End Support Unit:

Similar to the BK end support unit, the BF end support unit is also used for the fixed end of the ball screw. However, the BF unit differs in terms of its design and construction. It features a flange-type bearing block that allows for easy mounting and installation. The BF end support unit is commonly used in applications where space is limited or when a compact design is required.

3.FK End Support Unit:

The FK end support unit is designed for the floating end of the ball screw. It consists of a bearing housing and a support block. The bearing housing is similar to that of the BK unit, providing a stable base for the ball screw assembly. The support block, however, allows for axial movement of the ball screw shaft, accommodating any thermal expansion or contraction. The FK end support unit ensures smooth linear motion while compensating for any misalignments or variations in temperature.

4.FF End Support Unit:

The FF end support unit is similar to the FK unit in terms of its function and design. It is used for the floating end of the ball screw and provides axial movement capability to compensate for thermal expansion or contraction. However, the FF unit differs in its structure, featuring a flange-type support block for easy mounting and installation. The FF end support unit is commonly used in applications where space is limited or when a compact design is required.

5.EK End Support Unit:

The EK end support unit is designed for the fixed end of the ball screw and is commonly used in high-speed applications. It features a lightweight and compact design, ensuring minimal inertia and reduced vibration. The EK unit provides excellent rigidity and stability to the ball screw assembly, allowing for precise linear motion even at high speeds.

6. EF End Support Unit:

Similar to the EK unit, the EF end support unit is also used for the fixed end of the ball screw in high-speed applications. It offers a flange-type design for easy mounting and installation. The EF unit provides exceptional rigidity and stability, ensuring accurate linear motion even at high speeds. Its compact design reduces inertia and minimizes vibration, making it ideal for demanding industrial environments.
