Product Description
Advantages and Features: Japan’s THK NSR20TBC Linear Guide is a two-part structure in which a cylindrical spline nut cut off 120° in the circumferential direction is installed in a cast iron casing with sufficient rigidity.
Therefore, the mating surface of the shell and the cylinder can be automatically aligned and can be used on rough equipment mounting surfaces.
It should be noted that although the guide rail slider can bear loads from the four directions of up, down, left and right. However, because the slider is in the form of self-aligning, it cannot withstand the rotational moment (MC) with a single axis. So you need to pay special attention to this when selecting.
Japan’s THK linear guide slider THK NSR20TBC Linear Guide is an ultra-high rigidity guide rail with a combined height The motion stability of THK NSR20TBC Linear Guide refers to the performance of the guide rails that do not crawl when moving at low speeds or with small amounts of movement. Smoothness is related to factors such as the structure of the guide rail, the matching of guide rail materials, the lubrication condition, the properties of the lubricant, and the stiffness of the transmission system for guide rail movement.
The total block length L shown in the table is the length with the dust proof parts, code UU or SS. If other contamination protection accessories or lubricant equipment are installed, the total block length will increase

Japan’s THK guide rail NSR-TBC type has a cylindrical spline nut with 120° cut off in the circumferential direction in a cast iron casing with sufficient rigidity, forming a two-part structure.
Therefore, the mating surface of the shell and the cylinder can be automatically aligned, and can be used on rough equipment mounting surfaces. It should be noted that although the guide rail slider can bear loads from the four directions of up, down, left and right.
However, because the slider is a self-aligning type, it cannot withstand the rotational moment (MC) with a single axis. So you need to pay special attention to this when selecting.

Japan THK NSR20TBC Linear Guide rust solution revealed Experienced operators of CNC lathes and machining centers
must have encountered this: when anti-rust cutting fluid is used in daily production, its anti-rust effect is said to be very good,
and the anti-rust period between processes of the processed products can also meet expectations.
The result is that rust often appears on the worktables and guide rails of production equipment CNC lathes and machining centers.
If the anti-rust performance of the processed work piece is acceptable, then the idea that the cutting fluid has poor anti-rust performance can basically be ruled out. It can also be ruled out that the corrosion of the guide rail is directly caused by the cutting fluid.
We can THK guide rail customization export to Singapore–Viet Nam–Malaysia–Indonesia–America etc. Because there are many types of THK products, we can not upload all of them at present. If you have problems about selecting proper bearings for your special applications
