Floated Side EF Series Ball Screw Bracket

Main Technical Parameters and Design
1. Extremely Compact Design:
The housing design is extremely streamlined, removing unnecessary structures to ensure functionality within the smallest possible envelope.
The flange mounting hole layout is compact, allowing for installation on very narrow equipment side walls or support plates.

2. Core Functionality Guarantee:
It uses a standard deep groove ball bearing internally, whose axial clearance naturally allows the ball screw shaft to expand and contract freely, perfectly achieving thermal compensation.
The bearing and shaft use a clearance fit, making installation simple and avoiding additional axial constraint forces.

3. Standardization and Compatibility:
Equipped with basic dust seals to meet general environmental protection requirements.
Its inner bore size series is completely compatible with the EK series, and the mounting flange hole spacing and shape are often designed to be consistent with or highly coordinated with the same specifications of the EK series, making equipment base processing simpler and the appearance more uniform.

Applications
The compact support pair composed of the EF and EK series is the ideal combination for the following applications:
Desktop precision equipment: X/Y/Z axes of desktop CNC machines, small laser engraving machines, and high-precision 3D printers.
Teaching and experimental devices: Automation teaching platforms, motion modules for physics experimental instruments.
Light industrial automation: Small assembly line modules, electronic component testing machines, and transmission support for light packaging machinery.
Any OEM project requiring a complete support system but limited by installation space or overall machine cost control.

The Floated Side EF Series Ball Screw Bracket perfectly embodies the design philosophy of "simplicity without compromise." Through meticulous engineering optimization, it condenses the functionality of the floating end into the smallest and most economical physical form. Choosing the EF series means you won't have to pay extra for unnecessary performance and space. Together with the EK fixed end, it provides a reliable, compact, and accessible high-precision transmission foundation for a vast number of small and medium-sized automation equipment, significantly lowering the barrier to entry for precision linear motion technology.
