Since the rolling elements in cylindrical roller bearings make line contact with raceways,these bearings can accommodate heavy radial loads . The rollers are guided by ribs on either the inner or outer ring ,therefore these bearings aer also suitablefor high speed applications.Furthermore, cylindrical roller bearings are separable ,and relatively easy to install and disassemble even when interference fits are required.
Double and multiple row bearing arrangments are also available.
Single row cylindrical roller bearings can accommodate heavy radial loads and high speeds. They are manufactured in several different designs,the main difference being in the configuration of the flanges .The most popular are the NU,N,NJ and NUP designs.

The cylindrical roller thrust bearing is applied to take axaial loads. It has a high load capacity. The housing washer and the shaft washer of it are made of bearing steel. The cage material can be copper base alloy,aluminum alloy,steel.the cylindrical roller thrust bearings made in NNN use copper base alloy as the basic cage material.Aluminum alloy & carbon steel and plastic are also available on the request of the clients.In that case,some special suffix should be appended to the bearing codes to show the difference.

Spherical roller bearings are double row,self-reraining units comprising solid outer ring with a concave raceway,solid inner rings and barrel rollers with cages.The inner rings with cylindrial or tapered bores.The symmetrical barrel rollers freely align themselves to the concave outer ring raceway.As a result,shaft deflections and mislignments of the bearing seats are compensated.
|
|
|
Tapered roller bearings are designed so the tapered vertex of the raceway surfaces of the inner and outer rings and rollers converge at one point on the certerline of the bearing. Due to this design feature,rollers move along the center of theraceway surfaces. The tapered rollers are guided by the compound force of the inner and oter raceway surfaces which keep them pressed up against the large rib on the raceway surfaces which keep them pressed up against the large rib on the inner ring.A large variety of these bearings,including single,double,and four row arrangements,are in use both in metric and inch series.

Cylindrical roller bearings
Cylindrical rollers have linear contact with the raceway,and the bearings can carry heavier load. Applications are found in situations characterized by heavy load and shock load and also high rotation speed.
The N type and NU type bearings can be movable along the shaft. They can adapt the position changes between the shaft and housing caused by the thermal expansion or the mounting erro and are most suitable for free end shafts.
NJ and NF types can accept certain axial load in one direction, and NUP type can accept certain axial load in two directions.
Inner ring and outer ring can be separable, and they are conbenient to mount and dismount.
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.
Applications of these bearings are mostly found in middle-sized and large-sized motors, electricity generators, internal comubustion engines,machine tool spindles, decelerarion devices, unloading and lifting machines and other industral machines.

NU type of cylindrical roller bearings, capable of axial movement, can adapt to the change of relative position between the shaft and shell caused by thermal expansion or installation error, suitable for being used as the bearing at the free end. NJ and NF type of bearings have some loading capacity in one-way axial direction. NN and NNU type of bearings, with high rigidity against radial load, are mainly used in the principal axis in machine tools. This type of bearings are mainly used in various industrial machines such as the motor, generator, gas engine, gas turbine, principal axis in machine tools, reduction gear, handling machine, etc.

SK series water ring vacuum pump and compressor are used to suck in or compress air and other air that have no corrosives, undissolvable, and without solid particles, in order to form the vacuum and pressure in the airtight container, gas mixed with a small amount of liquid is allowed. SK series water ring type vacuum pump and compressor are widely used in machinery, petrochemical industry, pharmacy, food, sugar industry and electronic field. Because in the course of job, the compressed gas is constant temperature, it is impossible to cause danger while compressing the explosive gas, thus its application is more extensive.
- Compact structure
- It is convenient to maintain
- Wide range of application
- save maintenance cost
- High efficiency, low noise
- international standard
- Safe and reliable
- Can work under hard environment
