LME-LUU Long Linear Motion Bearing with Ball Construction
The long type linear bearing carries heavier load and guides better than the standard type, apart from a large increase in the length.
It is built with two cages, and each cage is provided with steel balls. This makes the product especially suitable for use in torque
load occasions. LM-LUU, LME-LUU, LMB-LUU three series are manufactured for different regions. For example,
the LM-LUU series is more suitable for use in Asia, while the LME-LUU series with difference in the size and tolerance
is more suitable for use in machines of European countries. In addition, the LMB-LUU series available in inch sizes enjoys
strengthened load capacity. As each series of long type linear bearing has a variety of dimensions for option, so that it can be applied in machines of different sizes.
The LM-LUU metric linear bearing available in metric sizes is widely used in Asian countries, such as Japan, South Korea,
China, and so on. It can be divided into a plurality of types according to different nominal shaft diameters, ranging from 6mm to 60mm.
With 80mm length and 32mm outer diameter, the product can be used to support the shaft with a nominal diameter of 20 mm.
Due to the smooth surface, the product is convenient to be processed. In addition, it can be installed in any direction,
and can work accurately requiring only one axis as the support. This metric linear bearing can well support the rotation
of the shaft and the parts on the shaft, and can maintain the normal working position and rotating precision of the shaft. Hence, it is a good choice for users.

The size unit of LME-LUU long linear motion bearing belongs to the metric system, making the product extensively used
in the European countries, such as Germany, Italy and other regions. Its applicable straight shaft diameter tolerance is
generally g6. Compared with the LM-LUU, these two series of long type linear bearings are approximately equal in structure and different in dimensions and bore diameter tolerances.

The LMB-LUU long linear bushing consists of a variety of types. The nominal diameter of shaft varies from 1/4 inch to 2 inch. In comparison with the standard type, this long type product enjoys larger load capacity. It can meet the demand of machinery in the Americas, so that it can be commonly found in this region. According to the size of the long linear bearing, 3-6 rows of balls can be installed to provide sufficient force, so as to further ensure the normal working of the shaft itself and the relevant parts on the shaft.
