Product Features

Standardized integrated structure

Precisely machined mounting base and bearing housing for easy installation and high positioning accuracy.

High-performance bearing configuration

Equipped with precision angular contact ball bearings, capable of withstanding combined radial and axial loads.

Fixed (BK) and supported (BF) types

BK type acts as the fixed side with high rigidity; BF type acts as the floating side to compensate for thermal elongation of the screw.

High precision and stability

Low runout, high rigidity, and stable rotation performance to improve transmission accuracy.

Simple structure and easy maintenance

Compact design, standard dimensions, interchangeable with common series on the market.

Lubrication and dustproof design

Built-in sealing structure to prevent dust and lubricant leakage, ensuring long service life.

Core Advantages

1. High rigidity & high load capacity

Effectively supports the ball screw, reduces deflection, and improves overall system stability.

2. Accurate positioning & low noise

High-precision assembly reduces vibration and noise during high-speed operation.

3. Easy installation & high compatibility

Standardized dimensions allow direct mounting without complex adjustment, widely compatible with various ball screws.

4. Thermal elongation compensation

The BF floating support design absorbs thermal expansion, protecting the screw and improving accuracy.

5. Long service life & high reliability

Good sealing and lubrication performance reduce wear and extend maintenance intervals.

6. Cost-effective

Stable performance, standardized design, and easy replacement effectively reduce equipment cost.
