THK NSR30TBC Block

Description

THK NSR30TBC Block

This THK NSR30TBC Block is for all machines that use this block.
THK THK NSR30TBC Block eliminates the friction between the ball and increase the grease retention, in order to achieve low noise, high speed and long maintenance-free operation. With this type, the LM block has a smaller width (W) and tapped holes.

Structure and specialty
The NSR-TBC is the only non-integrated LM block construction in the LM Guide series. It is housed in a cast iron casing with sufficient rigidity.
The cylindrical spline nut of 120° was removed in the circumferential direction to form a structure composed of two parts. Therefore, the mating surface of the outer casing and the cylinder can be automatically adjusted
Heart, so it can be used on rough mounting surfaces.
[can carry loads in all directions]
The NSR-TBC type has four rows of steel balls, and is divided into two rows, which are placed on the shoulders of the LM rail, and can withstand loads from four directions of up, down, left, and right. but
Yes, because of the self-aligning form, the single-axis cannot withstand the rotational moment (MC).
[Easy to install and adjust accuracy]
The NSR-TBC type has high automatic adjustment and self-aligning ability, so even if the installation accuracy of the two axes is not adjusted well, the LM block can be mistaken.
Poor absorption does not hinder the performance of the exercise, so it does not degrade the performance of the machine.
