The installation size of QEH15CA is the same as that of EGH15CA, because there is a ball retainer inside to separate the friction between the steel balls, which reduces the friction between the steel balls and reduces the noise of the slider on the track. In fact, the SSR15XW series can replace EGH15CA and THK, with low cost and fast delivery time! Welcome customers to call and inquire! Features of the QEH15CA series of silver linear guides: (1) Low noise design. The use of synchronous couplings allows the balls to be evenly and equally spaced, eliminating the metallic sound of ball to ball collisions and effectively reducing the intensity of sharp high-frequency sounds. The total noise intensity is effectively reduced by about 7.7 decibels in various speed ranges compared to the old series.

(2) The self-lubricating design does not require the patented synchronous coupling to have an oil storage space in the middle interval, which can supply the lubrication needs of the steel ball during operation. When passing through the directional rotating part, the lubricating oil can be evenly replenished in the oil storage space, continuing to evenly lubricate the steel ball. Therefore, the frequency of supplementing lubricating oil can be effectively reduced. After testing, high-performance lithium soap based grease is added before leaving the factory, which can be used continuously for over 2500 kilometers without fatigue damage at 0.2 times the dynamic rated load. So, high-performance lubricating grease is added at the factory, which can ensure its service life without maintenance under normal use.

(3) To improve the smoothness of motion, traditional linear slides without synchronous couplings start running. The steel ball on the load side will move first, and then push the direction rotating part and the steel ball inside the no-load side, causing a chain of back and forth collisions, resulting in significant fluctuations in frictional resistance. The Q1 Type linear slide rail using SynchMotionTM technology has a synchronous coupling that connects all the steel balls in the same cycle together. Therefore, when the slider starts moving, all the steel balls start almost simultaneously, and there is no back and forth collision between the steel balls. While maintaining a certain degree of motion inertia, the fluctuation amplitude of frictional resistance can be effectively reduced.

(4) The spacing design of the high-speed design synchronous coupling can eliminate the mutual friction between the balls, and HIWIN's patented design allows for circular linear contact between the balls and the synchronous coupling, reducing the contact area between the two and effectively reducing frictional resistance, making SynchMotionTM silent linear slide rail have excellent high-speed performance.
