wind strength turntable bearings
Wind energy slewing bearings
Kaydon engineers apply their experience and expertise to produce a vast variety of solutions to address the most exceptional bearing challenges, producing Ever-power’s leading distributor of wind turbine bearings. Kaydon has the experience and capacity to support important pitch, yaw and gearbox applications in devices from 200 kW to 5.0 MW and beyond.
Whether the necessity is for huge or low wind acceleration, land based or off shore, 200 kW or 5.0 MW-along with meeting critical consumer requirements and industry rules such as for example those specified by Germanischer Lloyd “Non-Marine Technology-Offshore Wind Strength”-Kaydon’s engineers can resolve even the most challenging challenges.
Slewing bearing is identical to usual bearings, it assembly simply by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing includes a lot of differences. Normally, slewing bearing offers huge dimensions, OD generally betwwen 0.4m to 10m, and some even to 40m. Under normal instances, slewing bearing operating in a minimal speed, high load state. Slewing bearing includes installation holes, lubricating holes and sealing unit. It has small stucture, convenience to steer rotate, simple installation and easy protection etc.
Four point contact – Four point contact ball bearings are radial solitary row angular speak to ball bearings with races that can support both axial and radial loads in either direction. Available with internal gear teeth, external gear tooth or gearless designs.
Eight point speak to – Eight point get in touch with ball bearings are radial double row angular speak to ball bearing with two independent ball tracks whose races support both axial and radial loads in either direction. Available with internal gear tooth, external gear the teeth or gearless designs.
Three row roller – three row roller bearings are designed with three independent rows of rollers to support a combo of axial and radial overturning moment loads. Readily available with internal gear pearly whites, external gear pearly whites or gearless designs.
Cross roller – Cross roller bearings were created with multi-directionally installed cylindrical rollers. They are made to accommodate radial, axial and overturning minute loads with a compact design footprint.
Ball Bearings
Angular contact – An angular contact ball bearing uses axially asymmetric races. Axial loads move in a straight range through the bearing, whereas a radial load normally takes an oblique course that will want to split up the races axially. So the angle of speak to on the inner race is the same as that on the outer race. Angular speak to bearings better support “mixed loads” (loading in both the radial and axial guidelines) and the contact angle of the bearing should be matched to the relative proportions of every.
Axial thrust ball bearing – Thrust ball bearings, made up of ball bearings reinforced in a ring, can be utilized in huge thrust applications where there is definitely excessive axial load. An axial load is normally transmitted straight through the bearing, while a radial load is normally poorly supported and will separate the races.
Deep groove ball bearings – In a deep-groove radial bearing, the race dimensions happen to be close to the dimensions of the balls that run in it. Deep-groove bearings can support bigger loads.

WireX wire-race turntable bearings
WireX® wire-race bearings
Ever-power bearings were actually created for military turret applications, where space and weight are at reduced and corrosion resistance is essential. They contain wire raceways inserted in light support rings, allowing for a high load capacity and huge diameter in a bearing that can be 60% lighter than one made entirely of steel. EP bearings are customized manufactured to fit each design and specification. EP bearings have been used efficiently in applications requiring a lightweight, corrosion-resilient bearing, including turrets, radar, and sonar.
