Thrust needle bearing

This type of bearings rolling way by separation circle and the needle with maintains a components, ceramic bearing a whole steel bearing has advantages and stamping processing thin groove circle (W) or cut the thick model the processing groove circle (WS) any combination. The separation is the type of bearings by precision stamping processing groove circle and the needle with maintains a components overall type bearings. May withstand the one-way axial load of these bearing. Take up the space is small, be helpful for mechanical compact design, mostly only used needle and maintains a module, and the shaft and shell mounting surface as a groove surface use.

"Taper roller bearings"

The rolling bearing-heating installation method with bosses these bearings are form roller, roller by inside circle big raised edge guide. Design makes the inner ring groove surface and outer groove surface and the rolling each cone roller bearing the vertex intersect at center of a line. Bearings can bear radial load and unidirectional axial load, double row bearings can bear radial load and to bi-directional load, apply to bear heavy load and impact load.

"Cylindrical roller bearing"

According to pack the roller bearing with different columns, cylindrical roller bearing can be divided into a single, double row and column cylindrical roller bearing. Angle contact ball bearing seal method which should be more is with a single maintains a cylindrical roller bearing. In addition, still have a single or double row full pack roller and other structure of the cylindrical roller bearing.

A single cylindrical roller bearing rings according to the different cent N raised edge type, and NU type fuel outlet, NJ type, NF type and NUP type, etc. Cylindrical roller bearing radial direction load capacity, according to the structure of the rings raised edge also can withstand the one-way or two-way axial load. NN type and NNU type double row cylindrical roller bearing compact structure, strong rigidity, carrying capacity, after the load little deformation, mostly for spindle bearing. FC, FCD, FCDP type four row cylindrical roller bearing may withstand the big radial direction load, more for rolling mill and other heavy machinery.

"Spherical roller bearing"

In the sphere of these bearing outer ring groove with double groove between inner circle with spherical roller, according to the internal structure of the different, divided into R, RH and RHA and SR four types. Because the circular arc of the outer groove center and bearing center is consistent, has the tone heart performance, so it can automatic adjustment for shaft or shell buckling or different caused by heart axis is not right. Can bear radial load and two-way axial load. Especially the radial direction load capacity, under heavy load and the applicable to impact load. Bearing its own sealing technology analytical cone hole through the use of fasteners or withdrawing bearing of unloading can make in the shaft installation. Spherical roller bearing can withstand the big radial direction load, at the same time also can withstand the axial load. The bearing outer ring groove is spherical shape, it has to regulate the heart performance, when the shaft bending stress and tilt to the centerline of the inner ring and outer ring centerline relative tilt does not exceed 1 ° ~ 2.5 °, the bearing can still work.

"Thrust roller bearing"

Thrust roller bearings include thrust self-aligning roller bearings, cylindrical roller thrust bearing and thrust taper roller bearings. Thrust self-aligning roller bearings can also carry axial and radial load, but the radial direction load may not exceed 55% of the axial load. This type of bearing away to another important features a automatically adjustable heart performance, so that its concentricity and buckling are not sensitive. As long as the load P and P. Not more than 0.05 C and axis rotation circle, bearing allows a range of self-aligning Angle. Cylindrical in an import bearings the installation method of small Numbers used in large bearings, and load increasing, while allowing the tone heart Angle will decrease.

"The spherical bearing"

Spherical bearing used in the priority requirements equipment and parts simple situations, such as used for agricultural machinery, transportation system or construction machinery. Mainly used to bear in the radial direction load primarily radial and axial union load, should not be commonly alone bear axial load, the bearing can separately installs inner circle (with the group of roller and keep the device) and outer ring. The bearing don't allow axis is tilted relative shell, employment in the radial direction load will generate additional axial force. The bearing axial clearance size, on the bearing can work a normal relationship, when axial clearance over hours, high temperature; The use of analytic method speed changing bearing axial clearance is bigger, bearing damage easily. So in the installation and operation to pay special attention to the bearing axial clearance and, when necessary, preloaded mounting can be made, and to increase the bearing rigidity.

"Joint bearings"

Joint bearings have type lubrication and self-lubrication type. Joint bearing is a kind of special structure of sliding bearings. TIMKEN bearing quality judgment in the structure of the pitfalls of it than rolling bearing simple, its main is a a within the sphere of the outer ring, can withstand the big load, according to a spherical outside the inner circle and the different type and structure, can bear radial load, axial load or radial, axial and existing joint load. Generally used to speed the lower swing motion (namely the form, you may also Angle must be within the scope of tilt Angle for movement (namely the tone heart movement), with the sliding surface for spherical move), in the axis and axle case hole not bigger concentricity, still can work normally

"Linear bearing"

Linear motion ball bearing basically use in mechanical equipment of linear reciprocating motion of the site, has less friction, sports flexible and convenient maintenance and replacement. It is widely used in textile machinery, printing machinery, pharmacy machinery, precision machine tools, electric cutting machine and automatic recorder, etc.

"Angle contact bearings"

Angle contact ball bearing, can both radial load and axial load, also can follow a pure axial load, limit rotational speed is higher. The axial load bearing capacity of the contact Angle is decided, the contact Angle is big, bear axial load of high ability.

"Bearing pressure"

Pressure separation is bearing type bearings, according to its structure form into one-way pressure ball and two-way pressure ball bearings. One-way bearing pressure can withstand a direction of the axial load, the double pressure bearing can withstand the two directions of the axial load. They are all can't bear radial load.
