Wind energy slewing bearings
Kaydon engineers apply their experience and expertise to produce a vast variety of answers to address the most exclusive bearing challenges, producing Ever-power’s leading provider of wind mill bearings. Kaydon has the experience and capacity to support significant pitch, yaw and gearbox applications in systems from 200 kW to 5.0 MW and beyond.
Whether the need is for substantial or low wind rate, property based or off shore, 200 kW or 5.0 MW-along with getting together with critical client requirements and industry regulations such as those specified by Germanischer Lloyd “Non-Marine Technology-Offshore Wind Energy”-Kaydon’s engineers can fix even the most difficult challenges.
Slewing bearing is identical to regular bearings, it assembly by rings and rollers. Nevertheless, compare to normal bearings, slewing bearing includes a lot of variations. Normally, slewing bearing possesses huge dimensions, OD generally betwwen 0.4m to 10m, and some even to 40m. Under normal conditions, slewing bearing working in a low speed, high load condition. Slewing bearing includes installation holes, lubricating holes and sealing system. It has compact stucture, convenience to guide rotate, simple assembly and easy repair etc.
Four point speak to – Four point contact ball bearings will be radial single row angular get in touch with ball bearings with races that are designed to support both axial and radial loads in either direction. Available with internal equipment teeth, external gear tooth or gearless designs.
Eight point get in touch with – Eight point contact ball bearings will be radial dual row angular contact 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 were created with three independent rows of rollers to accommodate a combination of axial and radial overturning moment loads. Offered with internal gear pearly whites, external gear pearly whites 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 instant 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 range through the bearing, whereas a radial load normally takes an oblique path that tends to want to split up the races axially. Therefore the angle of speak to on the inner competition is equivalent to that on the external race. Angular get in touch with bearings better support “mixed loads” (loading in both the radial and axial directions) 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, works extremely well in high thrust applications where there is definitely large axial load. An axial load is normally transmitted straight through the bearing, while a radial load can be poorly supported and will separate the races.
Deep groove ball bearings – In a deep-groove radial bearing, the race dimensions will be near 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 formerly created for military turret applications, where space and excess weight are at reduced and corrosion resistance is essential. They consist of wire raceways inserted in lightweight support rings, allowing for a higher load capacity and significant diameter in a bearing which can be 60% lighter than one produced entirely of metal. EP bearings are customized manufactured to match each design and specification. EP bearings have been used efficiently in applications requiring a lightweight, corrosion-resilient bearing, which includes turrets, radar, and sonar.
