Bearing

For use in machine-tool spindles, floating-displacement bearings are hybrid ball bearings with a surface-ground inner ring of Cronidur 30 high-performance bearing steel.

For applications requiring friction-free motion with zerobacklash, such as stamping dies, injection molds, and assembly and inspection machines, designers can now use linear-guide elements in diameters ranging from 3 to 100 mm.

Bearing maker SKF has established a central library on its network to store engineering calculations for reference and general use.

The SLS and SLF Series of industry-standard support bearing assemblies provide cost savings as they eliminate design and assembly time.

More-powerful controllers and better software lead to broader applications for magnetic bearings.

Fitting machine tools with roller linear guideways can improve accuracy, surface finish, feed speed, and productivity.

A new Series of inch-dimension linear ball bearings feature a compact design and recirculating balls that reduce friction for fast and precise load transport in linear-guide applications.

Dry-running, antifriction precision linear bearings are completely free of organic lubricants,

Ball screws often have trouble delivering extremely fine movement and slow motion, like moving 1 m m/sec.

Graphite-metal bearings can handle harsh environments that toast liquid-lubricated types.

MRC Bearings now offers precision-finished, silicon-nitride rollers separately, or installed in its line of aerospace hybrid roller bearings.

Opening up running clearances in sleeve bearings helps prevent seizing when oil runs dry.

Integrated flexpin bearings from The Timken Co., Canton, Ohio (www.timken.com), cut part count and raise power density in planetary transmissions.

Coatings make more efficient use of bearing materials and eliminate secondary machining and installation.

Heat and contaminants are the biggest enemies of bearing grease and oil.
