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

LMEK50UU Linear Bearing – 50 mm Shaft Diameter
Super heavy-duty, low-friction linear bearing for smooth, exceptionally high-capacity linear motion in large-scale industrial applications.
The LMEK50UU flanged linear bearing delivers smooth, low-friction linear motion for a wide range of applications, from semi-conductor manufacturing to food processing and transportation.
Manufactured to European metric standards, it ensures full interchangeability with standard linear components and integrates reliably into industrial automation and machinery systems.
With an inner diameter of 50 mm, an outer diameter of 75 mm, a flange diameter of 112 mm, and a length of 100 mm, this bearing provides exceptional performance in super heavy-duty, ultra-high-load assemblies.
Ideal for Very Large-Scale Industrial Equipment
This bearing is commonly used in applications requiring precise, exceptionally high-load linear movement and ultimate reliability, making it suitable for very large-scale industrial equipment and heavy-duty machinery.
Its robust design and excellent dust protection make it suitable for demanding environments such as semiconductor manufacturing equipment, food processing machinery where hygiene and reliability are paramount, and various transportation systems where consistent and smooth operation is crucial.
Its impressive sizing and capacity make it ideal for integrating into the largest gantry cranes, heavy-duty presses, and critical components of large-scale manufacturing lines.
Engineered for Precision and Durability
The LMEK50UU is engineered for exceptional performance. Its naturally self-aligning design offers flexible mounting options, accommodating minor misalignments.
A double rubber lipped seal provides high dust protection, enabling the bearing to perform in the most demanding environments by shielding against dirt and debris.
Requiring little to no relubrication and with minimal ball-to-raceway contact, a long lifetime is guaranteed, reducing wear and extending service intervals.
The precision-ground raceway surface ensures extremely low friction and quiet operation, contributing to overall system efficiency.
As part of Kiwi Motion’s European-standard LMEK Series, LMEK50UU ensures compatibility with metric linear systems and simplifies maintenance, replacement, or system upgrades.
LMEK50UU System Compatibility
Compatible with Kiwi Motion’s KM-W, KM-WRB, and KM-WV linear shafts, the LMEK50UU is a dependable choice for applications requiring precise and reliable linear guidance.
