Cylindrical Roller Bearings are designed to carry heavy radial loads. These bearings are made with a single row, double row sof rolling elements to meet an application's radial load requirement. Available in many standard series and configurations, they are widely used in multiple industries. The combination of high load capacity, moderate speed rating, and industry interchangeability make it one of the most popular bearing designs.
Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring. This is especially important when accommodating thermal expansion, where both rings must be press-fitted.
Bearing features: High load carrying capacity, High stiffness,Accommodate axial displacement,Low friction,Long service life,Enhanced operational reliability,Separable and interchangeable
Applications: large and medium-sized electric motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction gearboxes, rolling mills, vibrating screens, and lifting and transportation machinery.
The internal structure of the cylindrical roller bearing adopts rollers arranged in parallel. Spacers or spacers are installed between the rollers, which can prevent the tilting of the rollers or friction between the rollers, which effectively prevents the increase of rotational torque.
