Wind energy slewing bearings
Kaydon engineers apply their experience and expertise to make a huge variety of answers to address the most completely unique bearing challenges, producing Ever-power’s leading dealer of wind mill 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 need is for huge or low wind swiftness, property based or off shore, 200 kW or 5.0 MW-along with achieving critical client requirements and industry regulations such as those specified by Germanischer Lloyd “Non-Marine Technology-Offshore Wind Strength”-Kaydon’s engineers can solve even the most difficult challenges.
Slewing bearing is identical to normal bearings, it assembly by rings and rollers. Even so, compare on track bearings, slewing bearing includes a lot of distinctions. Normally, slewing bearing possesses huge dimensions, OD usually betwwen 0.4m to 10m, plus some even to 40m. Under normal instances, slewing bearing working in a minimal speed, high load state. Slewing bearing includes mounting holes, lubricating holes and sealing machine. It has small stucture, convenience to steer rotate, simple installation and easy maintenance etc.
Four point get in touch with – Four point speak to ball bearings will be radial one row angular get in touch with ball bearings with races that can support both axial and radial loads in either course. Available with internal gear teeth, external gear tooth or gearless designs.
Eight point get in touch with – Eight point speak to ball bearings happen to be radial twice row angular get in touch with ball bearing with two independent ball tracks whose races support both axial and radial loads in either direction. Offered with internal gear teeth, external gear tooth or gearless designs.
Three row roller – three row roller bearings were created with three independent rows of rollers to support a mixture of axial and radial overturning moment loads. Available with internal gear teeth, external gear teeth or gearless designs.
Cross roller – Cross roller bearings are designed with multi-directionally installed cylindrical rollers. They are designed to accommodate radial, axial and overturning moment loads with a concise design footprint.
Ball Bearings
Angular contact – An angular contact ball bearing uses axially asymmetric races. Axial loads pass in a straight series through the bearing, whereas a radial load normally takes an oblique course that tends to want to separate the races axially. So the angle of contact on the inner competition is equivalent to that on the external race. Angular get in touch with bearings better support “combined loads” (loading in both the radial and axial guidelines) and the contact angle of the bearing should be matched to the relative proportions of each.
Axial thrust ball bearing – Thrust ball bearings, made up of ball bearings supported in a ring, can be utilized in high thrust applications where there is certainly large axial load. An axial load is certainly transmitted immediately through the bearing, while a radial load is usually poorly supported and will separate the races.
Deep groove ball bearings – In a deep-groove radial bearing, the race dimensions are near the dimensions of the balls that run in it. Deep-groove bearings can support higher loads.

Ever-power bearings were originally made for military turret applications, where space and pounds are at reduced and corrosion resistance is essential. They contain wire raceways inserted in light-weight support rings, allowing for a higher load capacity and huge diameter in a bearing which can be 60% lighter than one built entirely of steel. EP bearings are customized manufactured to match each design and specification. EP bearings have been used efficiently in applications requiring a lightweight, corrosion-resistant bearing, which include turrets, radar, and sonar.
