The N/O type uses a needle roller cage. This guide rail is suitable for high-load applications. The tightly arranged needle rollers on the cage make this guide rail highly rigid.
A groove or ridge of metal or other material that bears, holds, guides, and reduces the friction of moving devices or equipment. Longitudinal grooves or ridges on the surface of guide rails used to guide and fix machine parts, special equipment, instruments, etc. Guide rail, also known as slide rail, linear guide rail, linear slide rail, used for linear reciprocating motion occasions, has a higher rated load than linear bearings, and can bear a certain torque, which can achieve high-precision linear motion under high load.
