Heavy Load Capacity Quiet Type Ball Linear Guideway

1. Automatic centring ability
From the place of circular groove (45 ° - 45 °) combination, in the installation, through the elastic deformation of the steel ball and the transfer of the contact point, even if the mounting surface more or less deviation, but also can be absorbed by the internal linear slide, resulting in the effect of self-aligning ability to get a high degree of accuracy and stability of the smooth movement.
2. Interchangeable type
Due to the strict control of manufacturing precision, linear slide size can be maintained at a certain level, and the slider has a keeper design to prevent the ball from falling off, so part of the series of precision has interchangeable, customers can order according to the needs of the guide and the slider, can also be separated from the storage of the guide and the slider, to reduce the storage space.
The customer can order the guide rail and the slider according to the need, or store the guide rail and the slider separately to reduce the storage space.
3. High rigidity in all directions.
The use of four rows of circular grooves, with four rows of steel balls and other 45 degrees of contact angle, so that the steel ball to achieve the ideal two-point contact structure, can withstand the load from the up and down and left and right directions; when necessary, can be applied to improve the rigidity of the pre-pressure.

Product description

SM series linear slide, for four rows of single arc tooth contact linear slide, while integrating the optimisation of structural design of the ultra-heavy-duty precision linear slide, compared with other linear slides to enhance the load and rigidity; with four-direction equal load characteristics, and self-aligning function, can absorb the mounting surface of the installation error, to get the demand for high precision. High speed, high load, high rigidity and high precision concept has become the future trend of the world's industrial product development, SLM four rows of super heavy-duty linear slides, that is, based on the concept of the development of the product.

Heavy Load Capacity Quiet Type Ball Linear Guideway

SM series is divided into non-interchangeable and interchangeable two types of linear slides, both with the same specifications and dimensions, the main difference lies in the interchangeable type of slider, guide can be single out of the interchangeable use, more convenient, but the combination of its accuracy can not reach the non-interchangeable type of ultra-high precision, but due to the manufacture of good dimensional control and stringent quality requirements, interchangeable type of combination of accuracy has reached a certain level for customers who do not need to install the linear slide pair, a good choice for customers. However, due to good dimensional control and strict quality requirements in manufacturing, the combined accuracy of the interchangeable type has reached a certain level, which is a good choice for the customers who do not need to install the linear slide in pairs. Linear slide product specifications mainly indicate the linear slide size, type, accuracy level, pre-pressure and other specifications, in order to order both sides of the confirmation of the product.
