Precision internal sleeve/spindle sleeve
Elongated internal bore structure with a flange at the front end, commonly used for: spindle sleeves, bearing housings, precision guides or support components.
Product Description
Precision inner sleeve/spindle sleeve (Inner Bore Sleeve/Spindle Sleeve)
Precision internal sleeves are hollow cylindrical structures, typically requiring long bore depths and high coaxiality. Their main function is...Support, guide, position or spindle mounting.
The key to these types of parts is not their appearance, but rather...Inner hole accuracy, straightness and surface qualityIt is a typical high-precision component that uses grinding instead of cutting.
Main features:
✔ High-precision internal hole size control (μm level)
✔ High consistency in inner hole roundness and straightness
✔ Excellent coaxiality of inner and outer diameters ensures spindle stability.
✔ Low surface roughness, suitable for high-speed or sliding applications
✔ Flange, step, or stop structure can be designed according to requirements.
