Ball Screw Brackets & Accessories

Ball screw brackets and accessories are key components ensuring the high-precision, high-rigidity, and stable operation of ball screw systems. Their primary classification is based on functional role, structural design, and service type.

The core components can be divided into four main categories:

Support Seat Units: Divided into fixed-end and support-end units based on the load and function they bear.

Fixed-end support seats (e.g., BK, FK, EK, AK series): Typically equipped with angular contact bearing assemblies, they bear bidirectional axial and radial loads and provide precise axial positioning of the screw, serving as the reference end for the entire transmission system.

Support-end support seats (e.g., BF, FF, EF, AF series): Typically equipped with deep groove ball bearings, they primarily bear radial loads and allow for slight axial thermal expansion displacement of the screw, providing auxiliary support and floating adjustment.

Standard functional accessories: Primarily lock nuts (e.g., RN series), used to tighten and preload the screw shaft end to the bearings within the fixed-end support seat. These are crucial standard components for torque transmission and eliminating backlash.

Custom machining services: These refer to the machining services provided to users of the lead screw shaft ends, ensuring a perfect match with standard support brackets. This mainly includes machining of the fixed end journal (compatible with BK/FK/EK/AK, etc.) and the support end journal (compatible with BF/FF/EF/AF, etc.), a crucial step in achieving plug-and-play functionality and lowering the assembly threshold.

The support bracket and accessory system, with its core division of labor between the fixed and support ends, supplemented by standard parts and custom machining, together constitute a complete, plug-and-play lead screw system installation solution.

With ISO9001 quality management, advanced equipment and technologies introduced from Germany, Japan, and Taiwan, and cooperation experience with customers from more than 30 countries, we support engineering teams from product selection to batch delivery and long-term replacement needs.

What Are Ball Screw Brackets & Accessories?

Ball screw brackets are mechanical support components used to fix and support both ends of a ball screw shaft. In a typical ball screw drive system, the fixed side support unit carries axial load and helps maintain positioning rigidity, while the support side support unit provides radial support and stabilizes shaft rotation.

Ball screw accessories are the related parts used for installation, connection, adjustment, and maintenance of the complete transmission system. These may include:

01
Ball Screw Support Units
02
Fixed Side Support Units
03
Support Side Support Units
04
Bearing Blocks
05
End Support Brackets
06
Lock Nuts and Washers

08
Couplings
09
Nut Housings
10
Mounting Screws
11
Dust Covers
12
Oil Seals
13
Spacers and Positioning Parts

Although these components may appear small, they directly affect installation accuracy, axial support, rotation stability, operating noise, and long-term performance of the complete ball screw system.

Common Industrial Applications

Ball screw brackets and accessories are widely used in equipment that requires stable rotary-to-linear motion conversion.

In CNC machine tools and machining centers, support units help position the ball screw shaft accurately and maintain stable feed movement under repeated operation. In industrial automation equipment, they are used with motors, couplings, linear guideways, and nut housings to build complete linear motion axes.

For linear modules and robotic linear axes, compact ball screw brackets make installation easier and help reduce assembly time. In semiconductor equipment, electronics manufacturing systems, laser cutting machines, and inspection equipment, properly matched support units help improve motion stability and repeatable positioning.
