The object only makes linear movement in one direction, and its motion can be described by position, speed, and acceleration at any time.

Common types of linear motion include horizontal motion, free fall, vertical thrown, and bevel motion.

Linear guides (Linear guideways) used for transmission purposes have different types according to different applications. The standard steel ball type - BR series linear guides can not only be used in general machine but in various machines; the ball caged type - BC series can increase the smoothness and is suitable for low noise occasions. And the miniature BM series with robust ball retention system can be used in more precise Medical and Laboratory equipment due to the advantages of volume, precision and corrosion resistance.

The BR standard linear guide has a built-in self-lubrication

system, no need to lubricate the pipeline system, and automatically maintain the lubricating oil film protection on the track surface for a long time, effectively extending the relubrication interval, and greatly reducing maintenance costs.

The standard applicable temperature is within -20 to 80 degree; we should be mindful of actual temperature in where we are and choose appropriate lubricant to fill.

Multiple advantages of application

1. It is easy for end users to install or replace the kit, and the BR lubricant reservoir can be replaced without removing the entire block.

2. Due to the high oil content of lubricant reservoir, it can effectively extended the relubrication interval, and the relubrication interval can be up to 4,000km.

3. By optimizing the film forming method, we can reduce the waste of lubrication oil, prevent environmental pollution, and be friendly to the environment.

4. The usage of high-performance lubrication oil that meets ISO3448 and viscosity grade 680 can make the oil and the block perfectly compatible. Allowable temperature range: -10~50⁰C (continuous operation) or -10~80⁰C (short-term operation)

SMAGIC always provides the best solution for customers while using linear guide in particular environment such as chrome-plating process for anti-corrosion. Please contact SMAGIC for immediate support for your needs.

The common structure of Ball screw- include internal and external circulation. Ball screw is a kind of steel ball placed between the nut and the screw to operate, which will be in a rolling contact mode. And then the rotating motion of the steel ball inside the nut is converted into a linear motion transmission component. General Motors are all rotating motions. But if you want the linear motion positioning, it is better to use screws. It's okay to use chains or belts, but the accuracy of the screw is much better.

Linear guide products have been through preservative treated before leaving SMAGIC factory, if customers will not use the products within a month, we highly suggest our customers to do regular anti-rusty work in light of temperature in different area. Please contact SMAGIC for further information.

In order to get high positioning accuracy, there are twoways to reach it. One is commonly known as to clear axial play to zero. The other one is to increase Ball Screw rigidity to reduce elastic deformation while taking axial load. Both two ways are done by preloading.

The housing method is an important point when selecting the appropriate ball screw specifications. For the example, please refer to section 6.2.1 of catalogue. When the conditions of usage need to be judged under strict conditions or when the judgment conditions are unclear in a special installation method, please contact SMAGIC.

The interchangeable type of block and rail are packed separately. Even customers install it by themselves; they still can reach accuracy standard as expected.rnFor non-interchangeable type of block and rail, SMAGIC already has implemented installation and measurement. When customers receive the product, any improper behavior to disassemble, interchange or change block direction will affect product warranty.

Ball screws generally take lubrication as the focus of maintenance

Lithium base lubricants are used for Ball Screw lubrication.Their viscosity are 30~40 cst ( 40˚C ) and ISO grades of 32~100.The chapter 6.5.4 table of catalogue shows the general indicators of lubricant inspection and replenishment intervals. Please wiping off the old lubricant attached to the screw shaft during replenishment before replenishing.

We suggest our customer to take account of BR self-lubricant system, BR self-lubricating kit is run by a high oil content of reservoir and optimization of film forming design adequate and proper amount of lubricant to grooves of rails, make supplementary periodically up to 4000km, end users can install or replace BR lubrication reservoir kit by themselves easily and directly without moving the block out. Please contact SMAGIC for obtaining further information.

If the linear guide or ball screw of SMAGIC needs to be repaired, do not disassemble by yourself. Please contact your local SMAGIC authorized distributors.
