SBR Linear Bearing Block



The SBR Linear motion ball slides are used to slide along SBR Supported Rods. These have a platform with four holes tapped for M5 screws.

With this platform it provides the perfect mounting point for any mechanism you require to move in a linear direction.

Supported smooth rod can be used over longer lengths without the need of additional supporting brackets, this allows for longer continuous lengths without a support block getting in the way.

The supported rod design also increase’s rigidity while maintaining the standard configuration of smooth rod set ups, this allows for heavier loads to be incorporated into your application.

To upgrade from standard smooth rod to supported smooth rod all you need to is replace the support blocks and smooth rod with a supported smooth rod. you can now use a SBR bearing with as many supported smooth rods joined together as you application requires. common applications are 3D printers, CNC machines, Robotics, Measuring equipment and instrumentation as well as Other Machinery.


  • SBR Linear Rail is a linear motion system produced at low cost for use with an unlimited stroke and a cylindrical shaft. Since the bearing ball is in point contact with the shaft, the use load is small. The steel ball rotates with little frictional resistance, so as to obtain high-precision smooth movement.
  • Straight optical axis is a product that has the guiding function of sliding bearing and can perform linear motion. The function of the linear guide motion is to support and guide the moving parts to make a reciprocating linear motion in a given direction. The design of the guide rail system strives to have a deeper contact area between the fixed element and the moving element. This not only improves the carrying capacity of the system, but also the system can withstand the impact force generated by intermittent cutting or gravity cutting, spreading the force widely and expanding The area to withstand the force.
  • The surface is chrome plated, hardened aluminum guide rail with hard shaft, exquisite appearance and precise performance.High carbon steel or bearing steel.
  • The head bearing adopts double dustproof design
  • Aluminum drag guide rail slider
  • There is a lock hole, the slider can be locked
  • Precision ball, the whole process is silent and the core is impact resistant.
