Wind energy slewing bearings
Kaydon engineers apply their experience and expertise to make a large variety of solutions to address the most one of a kind bearing challenges, making Ever-power's leading dealer of wind turbine bearings. Kaydon gets the experience and capacity to support essential pitch, yaw and gearbox applications in systems from 200 kW to 5.0 MW and beyond.
Whether the necessity is for substantial or low wind velocity, terrain based or off shore, 200 kW or 5.0 MW-along with assembly critical client requirements and industry rules such as those specified by Germanischer Lloyd "Non-Marine Technology-Offshore Wind Strength"-Kaydon's engineers can resolve even the most challenging challenges.
Slewing bearing is same as typical bearings, it assembly by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing has a lot of dissimilarities. Normally, slewing bearing provides huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal situations, slewing bearing working in a low speed, high load condition. Slewing bearing includes mounting holes, lubricating holes and sealing machine. It has compact stucture, convenience to guide rotate, simple unit installation and easy protection etc.
Four point speak to - Four point contact ball bearings are radial solitary row angular speak to ball bearings with races that are designed to support both axial and radial loads in either way. Available with internal equipment teeth, external gear teeth or gearless designs.
Eight point contact - Eight point speak to ball bearings will be radial twice row angular speak to ball bearing with two independent ball tracks whose races support both axial and radial loads in either direction. Offered with internal gear pearly whites, external gear tooth or gearless designs.
Three row roller - three row roller bearings are designed with three independent rows of rollers to accommodate a combination of axial and radial overturning moment loads. Obtainable with internal gear tooth, external gear the teeth 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 second loads with a compact design footprint.
Ball Bearings
Angular contact - An angular contact ball bearing uses axially asymmetric races. Axial loads pass in a straight line through the bearing, whereas a radial load normally takes an oblique way that will want to split up the races axially. Therefore the angle of get in touch with on the inner competition is the same as that on the outer race. Angular speak to bearings better support "put together 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, composed of ball bearings reinforced in a ring, can be utilized in substantial thrust applications where there is normally substantial axial load. An axial load is certainly 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 are near the dimensions of the balls that run in it. Deep-groove bearings can support higher loads.

Ever-power bearings were at first suitable for military turret applications, where space and excess weight are at reduced and corrosion resistance is vital. They consist of wire raceways inserted in light support rings, enabling a high load capacity and significant diameter in a bearing which can be 60% lighter than one made entirely of metal. EP bearings are customized manufactured to fit each style and specification. EP bearings have been used efficiently in applications needing a lightweight, corrosion-tolerant bearing, which include turrets, radar, and sonar.
