Wind energy slewing bearings
Kaydon engineers apply their experience and expertise to make a wide variety of answers to address the most unique bearing challenges, producing Ever-power’s leading provider of wind turbine bearings. Kaydon has the experience and capacity to support critical pitch, yaw and gearbox applications in systems from 200 kW to 5.0 MW and beyond.
Whether the necessity is for high or low wind swiftness, territory based or off shore, 200 kW or 5.0 MW-along with achieving critical buyer requirements and industry restrictions such as those specified by Germanischer Lloyd “Non-Marine Technology-Offshore Wind Strength”-Kaydon’s engineers can fix even the most difficult challenges.
Slewing bearing is identical to usual bearings, it assembly simply by rings and rollers. Even so, compare on track bearings, slewing bearing includes a lot of variations. Normally, slewing bearing provides huge dimensions, OD usually betwwen 0.4m to 10m, and some even to 40m. Under normal instances, slewing bearing functioning in a low speed, high load state. Slewing bearing includes mounting holes, lubricating holes and sealing device. It has small stucture, convenience to steer rotate, simple set up and easy repair etc.
Four point contact – Four point contact ball bearings will be radial solo row angular contact ball bearings with races that can support both axial and radial loads in either path. Available with internal equipment teeth, external gear teeth or gearless designs.
Eight point speak to – Eight point speak to ball bearings happen to be radial double row angular speak to ball bearing with two independent ball tracks whose races support both axial and radial loads in either direction. Obtainable with internal gear pearly whites, external gear teeth or gearless designs.
Three row roller – three row roller bearings are designed with three independent rows of rollers to accommodate a mixture of axial and radial overturning moment loads. Readily 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 point in time loads with a concise design footprint.
Ball Bearings
Angular contact – An angular contact ball bearing uses axially asymmetric races. Axial loads complete in a straight collection through the bearing, whereas a radial load takes an oblique path that will want to split up the races axially. So the angle of contact on the inner competition is equivalent to that on the external race. Angular contact bearings better support “merged loads” (loading in both radial and axial directions) and the contact angle of the bearing ought to 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 used in huge thrust applications where there is definitely huge axial load. An axial load is definitely transmitted straight through the bearing, while a radial load is poorly supported and will separate the races.
Deep groove ball bearings – In a deep-groove radial bearing, the race dimensions are close to the dimensions of the balls that run in it. Deep-groove bearings can support bigger loads.

WireX® wire-race bearings
Ever-power bearings were originally made for military turret applications, where space and fat are at reduced and corrosion resistance is essential. They consist of wire raceways inserted in lightweight support rings, allowing for a high load capacity and significant diameter in a bearing which can be 60% lighter than one made entirely of steel. EP bearings are customized manufactured to match each design and specification. EP bearings have been used successfully in applications needing a lightweight, corrosion-tolerant bearing, including turrets, radar, and sonar.
