THK NRS 65LA linear guide block
Ultra-heavy load(radial type) Model NR
This model is an ultra-heavy type of LM Guide that achieves a deep grooved raceway with its diameter more approximate to the ball diameter than the conventional type and has high rigidity, vibration and shock resistance, and damping characteristics, which are required for machine tools. As a result, it is optimal for receiving a radial load in particular.
