Linear motion sliding roller bush bearing

  There is a variation of linear roller bush bearing, where cylindrical rollers are separated by shims as fully loaded variable bearings and angular elements. The design with gaskets makes the operation of the device particularly quiet and sealed on the surface. Fully loaded linear cyclic roller bearings are suitable for applications at high temperatures, high speeds, and acceleration. Due to the 90 ° alignment of the two recirculating rollers, angular elements are particularly suitable for applications with enclosed layouts. This design is sealed on all sides.
  High precision rollers are installed on the track platform with extremely high flatness produced by precision grinding, resulting in high rigidity and precision. In addition, the mutual difference in assembly height can be selected up to 2 μ m, which can evenly distribute the load even when multiple are used simultaneously. It can guide the rollers correctly without tilting, and achieve extremely stable and smooth linear motion.

Maintenance of linear roller bush bearing :
Inject anti-corrosion oil into the interior of linear bearings. If lubricating with grease, first remove the anti-corrosion oil with kerosene or organic solvent, air dry, and then add lubricating grease. If lubricating with oil, it is not necessary to remove the anti-corrosion oil. According to temperature changes, ISO viscosity grade VG15-100 lubricating oil can be selected. Shaft lubrication can be supplied from the oil supply pipe or from the oil hole on the outer bearing seat. Due to the fact that the sealing ring will scrape off the lubricating oil, oil lubrication is not suitable for bearings with sealing rings without holes.

matters needing attention:
1. Prevent rusting
When directly taking the linear roller bush bearing by hand, it is necessary to thoroughly wash off the sweat on the hands and apply high-quality mineral oil before operation. Especially during the rainy season and summer, attention should be paid to rust prevention.
2. Keep the environment clean
Keep the linear roller bush bearing and its surrounding environment clean. Even tiny dust that cannot be seen by the naked eye entering the guide will increase its wear, vibration, and noise.
3. Installation should be done carefully and meticulously
When using and installing, it is necessary to be careful and careful. Strong stamping, direct hammering with a hammer, and pressure transmission through rolling elements are not allowed.
4. The installation tools should be suitable
Use appropriate and accurate installation tools, try to use specialized tools, and avoid using fabrics and short fibers as much as possible.
