Cylindrical Roller Bearings
Cylindrical roller bearings are available in many designs, series, variants and sizes. The main design differences are the number of rows of rollers and the inner/outer ring flanges and cage design and material.
Bearings are capable of handling the challenges of radially heavy loads and high rotational speeds. Accommodating axial displacement (except for bearings with flanged inner and outer rings), they provide high stiffness, low friction and long service life.
Cylindrical roller bearings are also available in sealed or split designs. In a sealed bearing, the rollers are protected against contamination, water and dust, keeping the lubricant inside and removing contamination. This results in lower friction and longer service life. Split bearings are primarily used in hard-to-reach bearing arrangements, such as crankshafts, where they simplify maintenance and replacement
Features and Benefits
High load capacity
high stiffness
Allow radial displacement
Except for bearings with inner and outer ring flanges.
low friction
Open sidewall design
Combined with the roller end design and surface finish, it promotes lubricant film formation, resulting in lower friction and higher axial load carrying capacity.
long lasting
The roller logarithmic profile reduces edge stress at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
Improve operational reliability
The surface treatment of the contact surfaces of the rollers and raceways facilitates the formation of a hydrodynamic lubricating oil film.
separable and interchangeable
The separate components of cylindrical roller bearings are interchangeable. This facilitates installation, disassembly and maintenance inspections.
application
Cylindrical roller bearings have properties that make them suitable for a variety of industrial applications and are necessary for some industrial applications. They can be located in fixed-end and floating-end bearing arrangements such as:
stationary gearbox
car gearbox
motor
Vibration motor
Wind Turbines
Construction machinery and equipment
Pumps and Compressors
Material handling equipment
Textile machinery
rail vehicle
rolling mill
