Cylindrical roller bearings from the reliable CHG Bearings manufacturer
The advantages of the double-row cylindrical roller bearings are high stiffness and high precision, so they are usually used as main shaft bearings of precision machine tools.
Four row cylindrical roller bearings are especially applied to rolling mills required high speed and precision, for example, wire mills, bar and shape mills, cold or hot sheet mills and cogging mills.
Types of Cylindrical Roller Bearings:
NU Design - Outer ring has two integral flanges, while inner ring had no flange.
N Design - Inner ring has two integral flanges while outer ring has no flange.
NJ Design - Outer ring has two integral flanges and inner ring has one integral flange.
NUP Design - Outer ring has two integral flanges and inner ring had one integral flange & loose flange ring for both side axial locations
The rigidity in carrying radial load in the NNU and NN types make them applicable for machine tool spindles.
FC, DCD and FCDP type can carry comparatively heave radial load and are mainly applied for mill rolls.
If you have some cylindrical roller bearings or other type bearings , welcome to inquiry us , we will do our best to support, Thanks

CHG Bearing:Bearings for wind turbinesApr 16, 2024Blade bearings are used to connect blades with hubs in MW wind turbines, and they also can adjust the windward direction of blades to ensure electricity production with power rating and the safe work of wind turbines. Usually, single or double rows four-point contact ball slewing bearings are used as blade bearings, which have preload, special designed seals, anticorrosion surfaces,etc.

CHG Bearing:The lifespan of bearingsMar 28, 2024The bearing life refers to the number of revolutions or hours experienced by the bearing before the occurrence of pitting under a certain load. The life of rolling bearings is usually defined by the number of revolutions or the number of hours worked at a certain speed. During this lifespan, no initial fatigue damage (such as spalling or defects) should occur on any bearing ring or rolling element.

Assembly and disassembly of tapered roller bearingsMar 21, 2024Tapered roller bearings can be mounted directly on a tapered shaft or on a cylindrical shaft through an adapter sleeve or withdrawal sleeve. A tight fit is obtained by axially moving the inner ring. The tight fit of the inner ring can be effectively controlled by measuring the reduction in radial clearance caused by the expansion of the inner ring.

Four row tapered roller bearingsMar 14, 2024It usually consists of two double-row inner rings, a double-row outer ring and two single outer rings. There is an inner spacer ring between the two inner rings, and there are two middle spacer rings between the three outer rings. Such a design The bearing can adjust the clearance to adapt to different working conditions.
