Product Description

Cylindrical roller bearings feature cylindrical rollers as rolling elements and are classified as separable bearings. The rollers and raceways engage in line contact, resulting in minimal friction between the rolling elements and the flanges of the rings. This design renders them suitable for high-speed rotation, though demanding high coaxiality during operation. Various configurations exist, such as N, NU, NUP, NF type, NJ type, etc. Through specialised optimised design, the line contact between rollers and raceways enables high load capacity. Primarily designed for radial loads, they offer exceptional load-bearing capability and maximum rotational speeds, suitable for fixed or floating end supports.

Features and Advantages

● High load capacity and rigidity

Linear contact between rollers and raceways delivers exceptional radial load capacity and rigidity. Specialised profiling and optimisation of flange and roller end faces further enhance axial load capacity while reducing friction.

● Diverse Cage Designs

Options include nylon, steel, and brass cages. Nylon cages offer low friction coefficients, lightweight construction, and reduced noise, while solid metal cages provide superior strength.

● Extended service life

The logarithmic profile of the rollers reduces edge stresses at contact points with the raceway, while also improving the bearing's tolerance for misalignment between the shaft and housing.

● Enhanced operational reliability

Optimised surface finish of rollers and raceways facilitates lubricant film formation, thereby improving dynamic performance.

● Separable and interchangeable

Cylindrical roller bearings exhibit high machining precision, with separable rings permitting interchangeability.

Product Applications

Medium-to-large electric motors, railway rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, gearboxes, rolling mills, vibrating screens, and lifting/transport machinery.
