Product Description

China Manufacturer TBR30 TBR30UU Linear Guide Rail Bearing

Metal linear bearing is a linear motion system produced at low cost for use with a cylindrical shaft with an infinite stroke. Since the bearing ball is in point contact with the shaft, the load is small. The steel ball rotates with very little frictional resistance, so that high-precision and smooth motion can be obtained.

FAQ1: What is the difference between TBR30 and TBR30UU linear bearings?

The difference between TBR30 and TBR30UU linear bearings lies in the design of the block or slider unit.
TBR30: This designation typically refers to the TBR series of linear guide rails and blocks with a 30mm diameter shaft. The core linear bearing component itself is often not explicitly called “TBR30” as a standalone part.
TBR30UU: The “UU” suffix on the TBR30 block indicates that it is a sealed unit. This means it has integrated seals to protect the internal components from dust, dirt, and other contaminants. The seals also help to retain the lubricant, extending the bearing’s life and reducing maintenance requirements.

FAQ2: How to mount TBR30 linear guide rails in CNC systems?

Mounting TBR30 linear guide rails in a CNC system is a relatively straightforward process, but it requires careful attention to detail for optimal performance.
Preparation: Clean the mounting surface of the machine and the linear guide rails. The rails are often coated in a protective oil, which you should clean off, and then apply a light, fresh lubricant.
Alignment: Position the rail onto the mounting surface. It is crucial to ensure the rail is perfectly straight and parallel to the other axes of motion. You may use a straight edge, a dial indicator, or specific alignment tools to achieve this.
Tightening: Begin by loosely tightening the bolts at one end of the rail. Then, gradually work your way down the rail, tightening the bolts in a staggered pattern. For a two-rail system, it’s essential to align both rails in parallel to prevent binding.
Final Checks: After mounting, slowly move the bearing blocks along the entire length of the rail to ensure there is no binding and the motion is smooth.
