Bearing modifications to meet design needs

Reali-Slim® thin section bearings come in many sizes and configurations, with attractive pricing on common modifications for demanding applications. Examples include custom diametral preload or internal clearance settings, precision class upgrades (some to ABEC 7F), custom lubricants, and duplexed sets.

HS slewing ring bearings solve space issues

HS Series slewing ring bearings provide exceptional load and thrust capacity in a surprisingly small envelope, thanks to a rectangular cross-section. They handle moment load up to 139,900 ft-lbs. and come in sizes from 20” to 47” O.D. Many are available from stock.

Thin section bearings the answer for compact designs

Reali-Slim® bearings are ideal for products made in a variety of sizes. The cross-section stays constant as bore diameter increases, providing the load capacity of standard bearings in less space. Choose from angular contact, radial contact, or 4-point contact.

Slewing rings position panels within 0.0006”

Kaydon Bearings has solutions for solar panel gearboxes, altitude-azimuth openings and other alternate energy applications. One customer uses a single Kaydon slewing ring bearing to rotate each panel instead of 2 bearings, with10 times the accuracy of a standard bearing.

Control Lets Scientists See the Sun with New Eyes

 

The Advanced Technology Solar Telescope (ATST) project is expected to provide the sharpest views ever taken of the solar surface. Scientists expect toA learn how cosmic magnetic fields are generated and destroyed, as well as the mechanisms responsible for solar variability that eventually affects the Earth.

The Telescope’s optic support structure, which includes the mirror assemblies, is expected to weigh nearly 75 tons, the mount base nearly 90 tons, and the Coude rotator 160 tons. The 84-foot diameter enclosure will be thermally controlled, highly ventilated, and will be a co-rotating hybrid that has independent rotation when the telescope is positioned at zenith. The enclosure is where the controllers and much of the instrumentation will be located.
