Online Exporter Nongeared Slewing Bearing - High quality 4 point contact ball turntable bearing for wind turbines – Wanda
Online Exporter Nongeared Slewing Bearing - High quality 4 point contact ball turntable bearing for wind turbines – Wanda Detail:
The raceway finish by grinding, the high level machining process and grinding process that ensured the precision for the double row slewing rings.
Mining equipment are characterized by their tough working conditions, like high temperature and heavy dust, and they are usually heavy-duty machines requiring slewing ring bearings of high load capacity.
The clearance cage enables the friction between rollers to be disappeared and prevent rollers from falling down on one side, which is able to obtain a stable torque. The rollers are orthogonal arranged, so only one set of the Crossed Roller Bearings can withstand the loads from different directions. Compared with the traditional series bearing, the current series bearings have increased the level of rigidity by three to four times.
Wanda Three-row roller slewing ring gear or Double axial Combination of Rollers and Ball swing bearing is apply for very high axial loads & moments as well as small radials efforts aggressive conditions.
We uses special sealing system gives fully tight bearings and we also propose integrated bearings with a lubrication system for such tough environment.
The three row roller slewing ring bearing and combined roll/ball swing bearings for stacker reclaimers, bucket wheels, ship loaders and Unloaders are very demanding applications.
without the mounting holes on both inner ring and outer ring, its requires a presser flange and housing for the installation. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, the installation has little impact on its performance, which can achieve the stable rotation accuracy and torque.
The cranes require slewing ring bearings with high load carrying capacity, higher reliability and safety. Our three-row roller with large diameter slewing bearings are well performed with all major classification requirements like DNV, ABS, LR,BV, GL, NK approvals.
We have strict production schedule to assure the delivery time, the production schedule as below:
A. Forging purchase period: 15-20 days
B. Production process:
1. Rough turning: 2-3 days
2. Raceway heat treatment: 2 days
3. Fine turning: 2 days
4. Gear cutting: 4-5 days
5. Drilling: 2-3 days
6. Final turning: 2 days
7. Assembling and Inspection: 2 days
C. Packing and delivery to Port: 3-5 days
Totally about 40-50days
We also supply Ball and Cross Rollers technology, and propose BALL AND ROLLER COMBINATION STRUCTURE design for very high radial loads and high speed like for active heave compensation winches. We also offer unique sealing complying with seawater environment, as well as thin stainless steel layer to increase lifetime on seal contact surface.
For large Offshore cranes, Bulk Handling, Marine cranes our Heavy design is also a popular solution, meeting requirements for huge axial loads& tilting moments.
