Tianjin Bemu Bearing Sales Co., Ltd.

Koyo Seiko Co., Ltd. and Toyoda Machine Works, Ltd. merged on January 1, 2006, and have made a new start as JTEKT Corporation. As a company centered on the automotive parts
business that possesses a firm technological base cultivated through long years of bearing and machine tool manufacturing, JTEKT will aim to win the further trust and high expectations of customers
and society.

The Timken Company is a leading global manufacturer of highly engineered bearings, alloy steels, and related components and assemblies. Our technologies and products turn up virtually everywhere
equipment moves or power is transmitted. By applying our knowledge of friction management and power transmission, we help our customers products run smoother, faster and more efficiently.

The rollers between the inner ring and outer ring are arranged crossways removely, they cut each other at right angles. Crossed-roller bearings
can accommodate the loads in any directions(such as axial load, thrust force and momentum). Since the rollers and the raceway surface contact with each other linearly , the possibility of the
bearings elastic deformation causd by the load is minor.

Thrust roller bearings are used for carrying the combined loads basically on axial loads, but the radial roads should not heavier than 55% of the axial loads. Compared with other thrust roller
bearings, needle roller thrust bearings have lower friction and higher speed. They are self-aligning. The rollers of the 29000 type is unsymmetrical spherical rollers, which will reduce the slide
rollers relative to raceway during operation. The rollers are long and with long diameter. The quantity of the rollers is large, and the carrying capacity of the roller is also large, so they can be
lubricated by oil or grease in individual low speed operation.. They are your first choise;80000 type cylindrical roller beaings , 90000 type tapered roller bearings and AKK type needle roller thrust bearings all can carry much heavier axial load in a directon than Thrust
ball bearings, and they have great rigidity but occupys less space. Cylindrical roller thrust bearings and needle roller thrust bearings apply to the low speed operation, and tapered roller
thrust bearings can operate in a little higher speed situation.

UBC Bearing of America, Inc. is a producer of high grade bearing components, as well as complete ball and roller bearings.

tapered roller bearings mainly carry the combined loads basically on radial loads. The carring capacity increases with the increasing of
the raceway angle. These beairngs are separable. They can classified into single row, double row, four low tapered roller bearings according to the
row number of the rolling element. The clearance of the single row tapered roller bearings must be adjusted by the buyers during mounting, but the double row and four low ones neednt, for theire
clearances have been set before leaving factory in accordance with the requirement of the buyers.

Tapered roller bearings have tapered inner and outer ring raceways, between which there are tapered tapered rollers. The projective lines of all tapered surfaces are meet at the point on the
bearing axes. This design enables the tapered roller bearings be suitable for carrying combined loads. The axial load carrying capacity increases with the contact angle (α).

tapered roller bearings are commonly separable, that is to say, the inner ring with rollers and cage assembly can be mounted separately
from the outer ring.

Spherical roller bearings are bearings which set spherial rollers between innerring with two raceways and shperical outer ring. The center of
curvature of outer ring raceway is identical to the center of bearings, so they are self-aligning. Once the deflection of shaft and housing occer, they can adjust by themselves, so that no burden is
put on the bearings. These bearings accommodate radial loads and axial loads in two directions. They have large load carrying capatiy, so they are suitable for application where there are haevy load
and impact loads. The bearings with tapered bore on the inner ring can be mounted directly, or mounted to the cylindrical shaft by adapter sleeve or dismantling cylindrical tube. Steel sheet stamping
cage, forming polyamide cage and copper alloy auto cage are used.

Spherical roller bearings accommodate maior radial loads, and stimultaneously carry a certain amount of axial loads. The outer ring
raceway are spherical form, so they are self-aligning. If the inclination inner ring centerline relative to outer ring centerline is less than  1° ∼2.5°, they can still work.

Spherical roller bearings are suitable for carrying heavy loads and impact loads, they are widely usded on metallurgy, rolling mill, mine, oil,
paper making, cement,sugar mill and other industries.

Spherical roller thrust bearings are single row and self-aligning. They comprise solid shaft washer, housing waher and cage with asymmetric
barrel- shape rollers. The cage retains the rollers with the shaft washer. These bearings are separable. The components can be mounted separately.
