LME8UU Closed Linear Bushing For 8mm Linear Shaft Rail

LME8UU Standard Closed Linear Bearing for 5mm Linear Bearing Shaft

LME8UU: 8x16x25mm

Compact Performance for Precision Motion Applications

The LME8UU linear bearing is a compact, high-precision bushing engineered for smooth linear motion in space-sensitive applications. Manufactured to European metric standards, it ensures full interchangeability and compatibility with a wide range of linear motion systems used globally. With an inner shaft diameter of 8mm, an outer diameter of 16mm, and a total length of 25mm, this bearing offers an excellent combination of a small footprint and reliable, high-performance motion. Its closed design, complete with dual rubber seals, provides strong protection against dust and moisture, making it a dependable choice for clean or semi-exposed environments.

LME8UU Ideal for High-Precision, Lightweight Systems

The LME8UU is well-suited for use in 3D printers, desktop CNC machines, lab automation platforms, and other lightweight systems that demand precise, repeatable linear travel. Its dimensions and performance characteristics make it ideal for fast, accurate motion in compact or multi-axis assemblies, where space and reliability are equally critical.

Engineered for Industrial Demands

Each bearing features integrated rubber seals on both ends that effectively block out dust, particles, and moisture. This seal design extends the operating life of the bearing while reducing the need for regular maintenance, even in open-frame machines or light industrial environments. The outer shell is constructed from hardened, precision-ground steel, offering excellent rigidity and wear resistance under continuous use. Internally, the bearing uses an industrial-grade resin retainer to maintain consistent ball spacing and circulation, which helps ensure smooth and quiet motion, even at higher speeds.

The design minimises ball-to-raceway contact, reducing rolling resistance, operational noise, and vibration. This results in lower energy consumption and greater efficiency in any motion system it is integrated into. At just 25mm in length, the LME8UU supports compact machine designs without sacrificing performance or load capacity. As part of the European Metric LME Series, it is fully interchangeable with other standard metric components, making it a straightforward solution for both new designs and retrofit applications.

LME8 UU System Compatibility

The LME8UU linear bearing is designed for use with Kiwi Motion’s range of precision ground shafts, including the KM/W, KM-WRB, and KM-WV series. Its seamless fit and proven durability make it an ideal choice for engineers building lightweight, high-speed, and accurate linear motion systems.
