5.       ball and roller combined slewing rings have a row of rollers and a row of balls into the same unit.

The slewing rings that we have supplied in the past including our standard ranges of slewing rings and specially designed slewing rings based on customer requirements and specifications. THB BEARING CO.,LTD can also supply replacement slewing rings of the major slewing ring brands such as INA, Roballo, Rothe Erde, Rollix Defontaine, Avon, Taperes, Kaydon, La Leonessa, RIMA, SKF, RKS, IMO, Titanus, Drecon, PSL, Jost, BPW&BRB Technologies Slewing Ring.

Slewing rings are widely used in many types of machinery, for example, slewing rings and turntables are suitable for foundry shakeout tables, palletizers, wire winders, cable reels, welding tables and turntable applications. Slewing rings can accommodate axial, radial and moment loads. Therefore slewing rings play a critical role in moving mechanisms; some types of slewing rings are used in hoists, excavators, truck-mounted cranes, tower cranes, solar panels as well as in moving bridges.

ball slewing ring bearings for excavators-THB BEARINGS

THB Single row four point contact slewing ring

is consisted of two rings (one inner ring and one outer ring.) It has compact

structure and light weight. As its balls are four point contacted with the

raceway, the slewing ring can take axial load, radial road, and tilting moment

at the same time. It is used widely for the application of rotary welding

machinery, medium and small series crane and excavators etc.

Our slewing

ring for the excavator slewing ring types will be updated from time to

time.

crossed roller slewing ring bearings for wheel loaders-THB BEARINGS

THB single row crossed roller slewing bearing is commposed of two seat rings.

It features compact in design, light in weight, high precision and small

fitting clearance.

As the rollers are 1:1 cross arranged , it is suitable for high precision

mounting and

capable to bear axial force, resultant moment and considerable large radial

force.

The single row crossed slewing bearings are widely used for hoisting,

transporting,

engineering machines as well as for military products. Such as, excavators,

wheel loaders, mini cranes, dridger machines, etc.

double row ball slewing ring bearings for stacker/reclaimers-THB BEARINGS

THB double-row Ball slewing bearing has three seat-rings. The steel balls and the spacers may be directly arranged into the upper and lower races.Two rows of steel balls with different diameters are fitted according to the force bom. Such open mode fitting features extraordinary convenience.The load angles of both upper and lower races are 90¡ã,which enable the bearing to bear large axial force and the tipping moment. When the radial force is larger than 1/10 of the axail force the races should be newly designed. As the axle and the dimension of the double-row ball slewing bearing are rather large,the bearing construction is sturdy ,hence it is especially suitable for tower cranes which require working radius over medium range,mobile cranes and loading and unloading machines

full complement cylindrical roller bearings for planetary gearbox and grabs-THB BEARINGS

THB Full complement cylindrical roller bearings are designed to carry heavy load. Comparing with traditional bearings with cage, full complement cylindrical roller bearings have much higher loading capacity. The radial cross section of the type of bearings is very small. So it can be very space-saving. However the limiting speed of the bearings is relatively lower. All the multi-row cylindrical roller bearings are with a lubrication groove and one nipple on the outer ring.

Cylindrical Roller Bearings mainly use in the fields of Large and medium-sized motors, locomotives and rolling stock, machine tool spindle, internal combustion engines, generators, gas turbines, deceleration box, rolling mill machine, planetary gearbox, mechanical grabs, idlers, pulleys, vibrating screen, hoisting as well as conveying machinery.
