The four-row cylindrical roller and track are line contact bearings. Bearing capacity is mainly radial load. The friction between the rolling elements and the fixed ring ribs is very low, suitable for high-speed rotation.

Application:

Such as automotive, rolling mill, mining, metallurgy, plastic machinery and other industries.

Type:

Depending on the ring has ribs or not, it can be divided into NU, NUP, NUP, N, NF and other linear bearings and NNU, NN and other double row bearings.
