nsk ntn koyo nachi cylindrical roller bearing
Cylindrical Roller Bearing
A radial cylindrical roller bearing consists of an inner and/or outer ring, a roller retaining cage and a complement of controlled contour cylindrical rollers. Timken cylindrical bearings provide the highest possible radial load capacity compared to other roller bearing types. Three basic styles are available to meet a variety of application requirements: One-row Cylindrical Bearings: Available in six types. Each has the same cage type, but inside and outside ring configurations vary to accommodate different application designs.
Two-row Cylindrical Bearings: Customized designs are available upon request (currently not a standard catalog item) and offer added radial capacity over traditional one-row types.
Four-row Cylindrical Bearings: Has an extremely high radial load capacity, but no thrust capacity. Mostly used in roll neck applications in the metals industry. FEATURES OF CYLINDRICAL ROLLER BEARINGSThe design allows linear contact of the cylindrical rollers with the raceways resulting in excellent radial load and impact load capacity The rollers have a slight crown to relieve the ends and reduce stress concentration The geometry allows for accurate machining to precision grade quality and use at high speeds The inner or outer rings can be separated, simplifying mounting and removal of the bearing The N and NU type with flanges only on the outer or inner rings, allow for shaft movement and thermal expansion but will not carry axial load Types NJ and NF have flanges on each end of the inner or outer races and a single flange on the inner or outer race to carry axial load in one direction The NUP and NH use a loose rib and thrust collar on the inner race to allow some axial load capacity in both directions Double row cylindrical like single row cylindrical, are available with either a separable inner or outer race Double rows are available with either a cylindrical or tapered bore Double row cylindrical can also be provided with lubrication holes and grooves in the outer ring Four row designs are used mainly on rolling mill roll necks were heavy radial load capacity is required Cage types are pressed steel, machined copper alloy, and pin type MAIN APPLICATIONSAUTOMOTIVE: Internal combustion engines transmissions, and cargo transportation ELECTRICAL: Large and medium sizes motors, traction motors and generators INDUSTRIAL: Gear boxes and machine tool spindles, steel mills
