Detailed Photos

Single-row cylindrical roller bearings are designed to withstand radial heavy loads and high speed applications. Both sides of the N-type bearing inner ring are equipped with integral guards, and the outer ring has no guards, allowing two-way axial displacement. An important feature is the separable design, which facilitates installation, and the individual components of the bearing are interchangeable.
