Product Description

The adjustable type linear bearing can adjust the tightness between the shaft and bearing. It is specially designed
with an open gap on the outside diameter for clearance adjustment. When a standard type product is installed
onto the shaft, inappropriate clearance will cause premature damage, failure, or unstable running to the linear
motion bushing. When the adjustable type product is installed into a bearing block that can control the outer
diameter, users can adjust the clearance according to the actual situation, so as to ensure the optimum working
condition. For example, the clearance can be zero or even negative in accordance with specific conditions.
This adjustable type linear bearing has three series, LM-AJ, LME-AJ, and LMB-AJ, which are respectively
corresponding to the use of standards in Asia, Europe and the Americas. With rich sizes in each series,
the product can meet the different demand of customers.
 
The LM-AJ linear bearing with slot for clearance adjustment is metric in size. It is crafted according to Asian standard,
so as to meet the demand for use in Asian machines. The product used for the shaft with a minimum nominal
diameter of 6mm has a length of 19mm, while the linear bearing with slot used for the shaft with a maximum
nominal diameter of 150mm is 240mm in length. Our different models of products can be applied in different machines,
in order to help the normal operation of shaft and shaft parts, as well as to ensure the precise working position.

As a professional standard linear bearing manufacturer and supplier in China, we also offer adjustable type linear bearing, round flange mount linear bearing, SC-UU slide block, SHF horizontal shaft support, and much more.
 
The LM-UU linear motion bearing is manufactured in line with Asia's mechanical standards, so that it is suitable for use in Asia. The products we offer include many models with the applicable shaft nominal diameter ranging from 3mm to 150mm. They differ in the main dimensions and tolerances, the degree of eccentricity, the maximum radial clearance, and the rated load. Therefore, this linear bearing for Asia market can be used in different sizes and models of machinery, serving to reduce friction and extend life of the equipment.
