SMR roller cage type linear slide

Since roller rolling elements are used instead of ordinary ball rolling elements, linear slide rails of the same size can be provided with higher rigidity and load capacity. In addition, with the patented design of the roller cage, it can make its operation more stable. Smooth, especially suitable for equipment requiring high precision, high load and high rigidity. Its high rigidity and high load characteristics can meet the needs of heavy-duty processing.

Features

High rigidity, super heavy load

The SMR series linear slide rail adopts the line contact force mode between the roller rolling element and the slider counter slide rail. Compared with the point contact mode of the general ball type linear slide rail, it provides lower elastic deformation when bearing the same load. , providing higher load capacity under the same outer diameter. Its excellent characteristics of high rigidity and high load can better meet the high-precision applications of heavy-duty processing.

Optimized design for four-directional loads

Through the structural stress analysis of the finite element method FEM, the optimized four-row roller 45° contact angle and high-rigidity cross-section design not only provide higher load capacity in the radial, reverse radial and transverse directions, but also Preload adjustment can be used to increase its rigidity, making it more suitable for various installation applications.

Roller retainer design, smooth walking

The simple and smooth roller return path design uses impact-resistant reinforced synthetic resin roller circulation accessories, combined with the design of the roller retainer, to prevent mutual friction between rollers and allow the rollers to circulate in and out of the load area and non-load areas. It is more stable in the load zone and can keep the rollers running in the same straight line, greatly improving its walking smoothness.

Low noise and good lubrication effect. The design of the roller cage reduces the metal collision between the rollers, reduces the overall operating noise, and can effectively maintain lubricating grease between the rollers and the cage. The lubrication effect is good and the overall performance is improved. It has excellent walking smoothness and service life, and can meet the needs of high-precision, high-reliability anti-smooth and stable linear motion.

Linear slide lubrication oil filling hole

SMR series linear slide rails provide lubrication and oil filling positions in the center of both end faces of the slide block, the transverse reserved holes in the end cover, and the reserved holes in the upper part. In order to prevent the intrusion of foreign matter, the horizontal reserved holes and the upper reserved holes of the end cover are not penetrated. If you have this requirement, please specify it when ordering. The types and sizes of oil nozzles used in each model are as follows.
