Ballscrew actuator that we ordered through Kiwi Motion looks and performs great. Swiss quality!
Well Specified Linear Actuators
The actuator runs smoother and quieter than previously used actuators. Also, it runs faster from start, so we can drive faster.

Superb service from start to finish
I can just tell Kiwi what I need and I can trust they will go away and sort the right product at the right time.

Well packaged Linear Shafts
Well packaged item, as described and dispatched quickly. Thank you
High Quality Linear Rail and Guides
We received the new components on the Wednesday afternoon and installed them the following morning. Parts were perfect and of great quality!
That you kindly for your assistance, fantastic service you’re running over there!

Product Details

LME5UU Standard Closed Linear Bearing for 5mm Linear Bearing Shaft
LME5UU: 5x12x22mm
Precision Linear Motion for Compact and Lightweight Applications
The LME5UU linear bearing is a small yet highly precise component designed to deliver smooth, low-friction linear motion in compact mechanical systems. Manufactured to European metric standards, it offers full interchangeability and compatibility with standard metric shafts and components. Featuring a 5mm inner shaft diameter, a 12mm outer diameter, and a total length of 22mm, this bearing is ideal for applications requiring minimal space without sacrificing performance.
LME5UU Perfect for Miniature Automation and Lightweight Equipment
Thanks to its compact size and reliable operation, the LME5UU is widely used in miniature automation devices, optical instruments, small robotics, and lab equipment where precise linear movement is essential. It excels in applications such as micro-positioning stages, small conveyor lines, and precision measurement tools.
Engineered for Longevity and Low Maintenance
The LME5UU features a hardened steel outer shell that provides excellent rigidity and wear resistance despite its small size. Dual rubber seals on both ends protect the internal raceways from dust and moisture, significantly reducing maintenance needs and enhancing service life. Inside, a polyamide resin retainer ensures smooth circulation of the bearing balls, minimising friction and noise.
The precision-ground internal raceways reduce rolling resistance and vibration, enabling quiet, efficient motion even at higher speeds. At just 22mm in length, the LME5UU supports compact mechanical designs where space is limited but accuracy and reliability remain crucial.
As part of the European Metric LME Series, this bearing guarantees seamless integration with existing metric shafting and linear motion systems.
LME5UU System Compatibility
The LME5UU is engineered to work effortlessly with Kiwi Motion’s linear shaft range, including:
- KM-W-5 CF53 Steel Linear Shafts
- KM-WW-5 CF53 Chrome Plated Steel Linear Shafts
- KM-WRB-5 Stainless Steel Linear Shafts
Providing a dependable solution for lightweight, high-precision linear motion applications.
