In practical industrial applications, cross roller slewing ring is called: "the machine joints"

The main applications are widely used: Truck cranes, railway cranes, harbor cranes, ship cranes, metallurgical cranes, container cranes, excavators, filling machines, Angular contact ball bearings as well as CT machine standing wave treatment, navigation, radar antenna base, deck crane bearing missile launchers , tanks, robots and a revolving restaurant, and so on. Slewing bearings are widely used in rotary initial application engineering machinery is also the most widely used in areas such as earth-moving machines, excavators, crushers, stackers and reclaimers, graders, rollers, compactors, drilling machines, drilling machines. Others include: Concrete: Concrete pump truck, concrete mixing machinery boom, with fabric machine.

The Features of Spherical roller thrust bearings

spherical roller bearing use asymmetrical rollers of spherical shape, rolling inside a house washer with a raceway with spherical inner shape. They can accommodate combined radial and axial loads and also accommodate misalignment of the shafts. They are often used together with radial spherical roller bearings. Spherical roller thrust bearings offer the highest load rating density of all Thrust Ball Bearings.Spherical roller bearing outer ring and the bearing housing bore should not use an interference fit with the inner ring and the journal should not be too tight, requiring adjustment nut should be used to produce energy in the installation more flexible axial displacement. Spherical roller bearings because if interference fit easily change the contact angle of the bearing, resulting in uneven distribution of bearing loads, cause high temperature. Therefore, this type of installation with the inner bearing journal and bearing outer ring and the housing bore, the general should be hands thumbs can just push the journal bearing and the housing bore for the best.

Slewing bearings

in the Rolling technical field wheel bearing in the first class products throughout the world. These mechanical components have repeatedly proved its high load capacity, wide range of applications and cost-effective. Due to their design, a single bearing can be Supported by the radial, axial and tilting moment loads. Therefore, in many cases, it can be replaced by a single bearing the combination of Radial Bearing and axial bearing of the bearing arrangement. In many cases, it is largely located in the adjacent structure Meter and bearing reduces installation cost and effort necessary. Double sealed wheel bearings, grease lubricated with high quality, it can lubricate the nozzle lubrication and very easy to install again. Bearing ring provides gearless, or to Achieve simple drive provided with external or internal gear bearings.

Crossed Roller Bearing Inspection noise type and identification of causes

Crossed Roller Bearings abnormal sound occurred during the operation, a wide range of formation mechanism is more complex, factors that are multifaceted, and various abnormal sound often added together, it is difficult to distinguish, mainly due to the following categories:
1. The bearing inner and outer raceway presence bump hurt, scratched or periodic vibration pulse serious defect.
2. Scroll surface bump hurt of rolling bearing, aperiodic oscillation pulse scratches and other defects caused.Periodic or aperiodic oscillation pulse
3. Since residual magnetism adsorption iron powder present on the raceways or rolling elements caused.
4. impurities or dust into the bearing raceway pulse caused by aperiodic vibration. Must be done in space when high cleanliness of cross roller bearing assembly.
5. aperiodic oscillation pulse violent collision between the rolling element and spacer blocks caused.
6. poor performance lubricants, rolling vibration pulse generated when the lubricant sliding friction between the rolling element and spacer blocks and the rolling elements running. Crossed roller bearings senior grease, in order to ensure the use of sophisticated demand environment.

Flange Slewing Bearing classification

In reality, very broad industrial applications, known as: "the machine joints", which are widely used in major applications: cranes, railway cranes, harbor cranes, ship cranes, worm gear speed reducer metallurgical cranes, container cranes, excavators, irrigation installed, as well as CT machine standing wave treatment, nautical instruments, radar antenna base, missile launchers, tanks, robots and a revolving restaurant, and so on. Slewing bearings are widely used, construction machinery was originally applied slewing ring is the most widely used in places such as earth-moving machinery, excavators, disintegration machine, stacker reclaimer, graders, rollers, compaction machines, self-aligning roller bearing drilling machines, boring machines. Others include: Concrete: Concrete pump truck, concrete mixing machine boom, belt fabric machine. 

Spherical roller bearings Needle Roller Bearing

Spherical roller bearings have two raceways between the inner and outer ring raceway is spherical, equipped with a drum-shaped roller bearings. The outer ring raceway curvature Taper roller bearings center and bearing center line, so has the same self-aligning ball bearing self-aligning feature. When the shaft, shell deflection occurs, you can automatically adjust load and axial load in two directions. Radial load capacity, for a heavy load, impact load conditions. Inner diameter is tapered bore bearings can be installed directly. Or using an adapter sleeve, remove tube installed in the cylinder axis. Cage with steel stamping cage, forming polyamide cage and copper alloy machined cage.For the self-aligning bearing, in the bearing housing bore the loading zone axis, using an intermediate mounting ring prevents tilting and rotating the outer ring. It should be deck crane bearing remembered that some dimensions of self-aligning ball bearing ball bearing protruding from the side, so the middle of the ring should be installed recessed to prevent damage to the ball. A large number of bearings are generally used mechanical or hydraulic press for the installation method.

Needle Roller Bearing Is there a hybrid ring

Left hand holding the bearing sleeve body, right hand toggle coat a small margin to rotate back and forth, listening to the bearings during operation if there is mixed response. inch bearing Most counterfeit products due to production conditions of backwardness, completely hand-mill operation, bearing the body in the production process will inevitably be braced with dust, sand a class of impurities, so that the rotation of the bearing ring or when there will be hybrid phenomenon does not run smoothly . This is to slewing bearing determine whether a product comes from a strict production standards, and the key with the regular operation of the machine manufacturer's brand products.

Deep groove ball bearings

Deep groove ball bearings are bearing the most common type. The basic model consists of a deep groove ball bearing outer ring, an inner ring, a steel ball and a group of holding structure into. Deep groove ball bearing type has two kinds of single and double row deep groove ball structure also split seal and open two structures. Dust closures material is steel stamping, just play simple to prevent dust from entering the bearing raceways. Anti oil type of contact seal, which can effectively prevent the grease within the bearing spill. Deep groove ball bearings mainly take radial load, but also to support radial and axial load. When the only radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, the performance with angular contact bearings, can withstand greater axial load, deep groove ball bearing friction coefficient is small, speed is also very high.

Flange bearings

The flange and the bearing became known as one of the bearing flange bearings, products with a flange on the outer ring, enabling axial positioning easy, no longer need housing, become more economical. It is low in order to get the bearing friction torque, high rigidity, good rotation accuracy, use a small diameter steel balls. The use of hollow shaft, ensuring lightweight space and wiring. When the end of the shaft is not connected pieces, such as plates need to be fixed in the plane, on a wall, flange bearings to reflect its superiority. In the ultra-small aperture miniature bearings, bearing dust cover plate can be divided into ZZ series, RS rubber bearing seals series, Teflon bearings seals series, flange series, stainless steel series, ceramic ball series. Miniature ball bearings with a wide range of uses. For high-speed rotation, low friction torque, low vibration, low noise requirements of the product.
