LME30UU Linear Bearing – 30mm Shaft Diameter

LME30UU: 30x47x68mm

Durable Linear Motion for Heavy-Duty Industrial Applications

The LME30UU linear bearing is designed to provide robust, low-friction linear movement in heavy-duty machinery and automation systems. Manufactured to precise European metric standards, it ensures full interchangeability with standard metric linear components worldwide. With an inner shaft diameter of 30mm, an outer diameter of 47mm, and a total length of 68mm, this bearing delivers high load capacity while maintaining smooth and reliable motion.

Suited for Heavy Machinery and Precision Automation

Thanks to its larger dimensions and increased rigidity, the LME30UU is ideal for use in industrial robotics, material handling equipment, large CNC machines, and other heavy automation platforms. It supports steady, vibration-free linear travel, ensuring precise positioning in demanding manufacturing and assembly processes.

Built for Strength and Low Maintenance

The LME30UU features a hardened, precision-ground steel outer shell that offers excellent durability and resistance to wear under intense load cycles. Its internal polyamide resin retainer maintains consistent ball spacing and smooth circulation, reducing friction and noise. The precision-ground raceways further minimise rolling resistance for efficient operation.

The bearing’s dual rubber seals protect against dust, dirt, and moisture ingress, significantly extending service life and minimising the need for frequent maintenance. Measuring 68mm in length, the LME30UU balances robust support with a design compact enough to fit in tightly configured machinery.

As part of the European Metric LME Series, this bearing is compatible with standard metric shafting, offering straightforward integration and interchangeability.

LME30UU System Compatibility

The LME30UU is engineered for compatibility with Kiwi Motion’s range of linear shafts, including the KM-W, KM-WRB, KM-WRA, and KM-WV series, making it an excellent choice for engineers requiring reliable, heavy-duty linear motion components.
