Cylindrical Roller Bearing NAS5060UU application and product ​description:

The NAS5060UU tape sealant is an important part of the mast crane, which is a fixed mounted crane, which is generally used in the port terminal. The mast crane is also called the pull rod or the pole, is the simplest lifting equipment.

Mast cranes are generally made of wood or steel.

This kind of crane has the characteristics of simple making, convenient assembling and disassembly,.

Large weight and small limit of construction site. In particular, the hoisting of large components and lack of large lifting machinery, this kind of lifting equipment more obvious its superiority. But this kind of crane needs to set more cable wind rope, mobile difficulty. In addition, its lifting radius is small, the flexibility is poor.

As a result, the mast crane is generally used for heavy components, heavy lifting projects, narrow construction sites, and lack of other suitable large lifting machinery. Since such cranes are relatively large, it is difficult to replace them, so as part of them, they must be durable.

UIB bearing NAS5060UU can meet its requirements. Other products of the same size as the NAS5060UU series include: NAS5064UU, NAS5068UU, NAS5072UU, NAS5076UU, NAS5080UU, NAS5084UU, NAS5088UU, and so on.
Our UIB bearing NAS5060UU belongs to roller bearing of pulley.

This type of bearing is a double row full roller bearing, which is designed as a pulley with a low end height. There are two types, namely the attached sealing gasket sealing and dustproof, with shielding, under relatively low speed rotation can withstand larger radial load and impact load, axial load can load.

The outer ring is easily fixed to the pulley. The inner ring width is designed to be larger than the outer ring width, which can save the padding of the pulley, and its double-row roller structure can withstand the torque of the rope position steadily. The bearing is surface treated and has corrosion resistance.

A: Single row cylindrical roller bearing;

B: Heavy duty cylindrical roller bearing, high load capacity cylindrical roller bearing

C: Double row cylindrical roller bearing

D: Four row cylindrical roller bearing.

Bearing characteristics:
High bearing capacity
High stiffness;

Allowable radial displacement
In addition to the inner and outer ring flange bearings.

Low friction (roller end/flange contact area)
Open flange design, together with the roller end design and surface finish, promote the formation of lubricant film, resulting in lower friction and higher axial load.

Long service life
The logarithmic curve profile of the roller reduces the edge stress of the roller/raceway contact and the sensitivity of the deflection to the neutral axis.

Improve operational reliability.
The surface finish of roller and raceway contact surface is conducive to the formation of fluid pressure lubricating oil film.

Separable and interchangeable.
The separation components of cylindrical roller bearings are interchangeable. This is easy to install, dismantle and maintain inspection.
