Product Description

Product General information
1, Low frictional linear motion
Steel balls are accurately guided by a retainer, so low frictional resistance and stable linear motion can be achieved.
Simple replacement of conventional plain bushings
It is easy to use Linear Bushings instead of conventional plain bushings, because both types are used with a round shaft, and no major redesign is necessary

2, Wide variations
For each dimensional series, standard, adjustable clearance and open types are available with and without seals, so the best linear bushing for the application may be selected. In addition to the standard type, the high-rigidity long type is available. These types can be selected to suit the requirements in applications.

3, Miniature linear bushing LM Compact design
Miniature Linear Bushing is very small in size, allowing for compact assembly in machines and equipment.

4,High Reliability
ERSK linear bearing has very stringent quality control standards covering every production process. With proper lubrication and use,trouble-free operation for an extended period of time is possible.

5,Smooth Operation
The high efficiency of linear shaft is vastly superior to conventional shaft. The torque required is less than 30%. Linear motion can be easily changed from rotary motion. The linear bearings are moved very smoothly in the linear shaft.

6,High Durability
Rigidly selected materials, intensive heat treating and processing techniques, backed by years of experience,have resulted in the most durable linear bearings manufactured.

7,Easy interchangable

8,Easy maintenance
the linear rails can replace the base surface installation, the old wear parts (rails and blocks) can be replaced, reduce costs.

9,Easy installation
the linear rails and carriages can be changed easily, reduce material costs, reduce product prices, reduce product replacement costs and time.
