Slewing Rings for Excavator
Feature: The speed of Slewing bearing is fairly low, usually below 10 r/min. Moreover, on most occasions, Slewing bearing doesn¡¯t slew continually, but only slew back and force in a certain angle like the so called Swing Bearing. Slewing bearing differs greatly from roller bearing in process techniques, material and heat treatment. Generally, Slewing bearing has gear ring as driving device and Seal Device to pretend dust. Unlike the common bearing fixed on the central pivot in the bearing box, Slewing bearing has big size and is attached to upper and lower plates by bolts.
Application:Slewing bearing is widely used in different industries. It is suitable for hoisting machine (truck crane, tower crane, etc.), construction machinery (excavator, loading and unloading machine), transporting machine, material processing machine, Metallurgy Machinery, food processing machine, military product (tank, santi-aircraft gun, radar, missile launcher, etc.), medical instrument research equipment, etc.

Double-row tapered roller bearings.
Please contact me if you need more information.
Because of more rows of rollers, the radial load capacity of double-row tapered roller bearings enhanced, at the same time, they are capable of carrying heavier axial loads in both directions. They are primarily used to carry combination of radial and axial loads, and limit axial displacement of the shaft (or housing) in both directions, so they can be used to locate axially in both directions.
The performance of the type TDO double-row tapered roller bearings is the same as the two single-row tapered roller bearings with back-back arrangement.
The double-row tapered roller bearings are easy to mount and dismount, and have high stiffness; therefore, they are usually used in the applications with changing loads, such as gear-boxes, etc. There is a spacer between the two inner rings, the radial and axial clearance can be adjusted by changing the width of spacers.
The type TDI double-row tapered roller bearings have a outer ring spacer, the clearance is adjustable, these bearings mainly used in roll neck under moderate loads.
Sized from 0.6250" (16 mm) inside diameter to 10.1250" (257 mm) outside diameter. Metric ISO sizes from 15 mm inside diameter to 160 mm outside diameter.
Both NTN and NTN-Bower brand names are available.
Deep groove ball bearings are particularly versatile. They are simple in design, non-separable, suitable for high and even very high speeds and are robust in operation, requiring little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions.
We can produce the diameter from 3mm~420mm deep groove ball bearings.
High quality, low price, good appearance, wonderful package.
The automobile wheel hub bearing function mainly is withstands the automobile the weight and provides the sentiment true guide for the wheel hub transmission.The wheel hub bearing both the withstanding radial direction load and withstands the axial load, is one extremely important security

Low price, high precision, excellent quality.
Thrust ball bearings from a shaft circle, a circle housings, as well as a ball and cage thrust component by component. Bearing is a detachable structure, easy-to-install, and because the ball washers and Cage components can be installed separately. One-way thrust ball bearings can withstand axial load in one direction, and to the axial direction for the single location but it definitely
can not afford any radial loads.
We can produce the diameter from 3mm~190mm thrust ball bearing.
