Hybrid Ball Bearing Benefits

 

High Speed-Oil mist lubricates up to three million DN with reduced skidding, wear, and heat generation: grease-lubricated hybrids up to one million DN. Ion doped races with self-lubricating retainers require no hydrocarbon or flurocarbon lubriction.

 

Extended Operating Life-3 to 5 times greater than that of steel when properly applied.

 

Marginal Lubrication-Ion- doped races with self-lubricating retainers require no hydrocarbon or fluorocarbon lubrication. By using dessimilar materials(Ceramic on steel) microscopic adhesion welding is eliminated.

 

Corrossion Resistance-Ceramic material resists corrosion and galling while thin-dense coating may be used to enhance hybrid.

 

High Stiffness-Modulus of elasticity 50% greater than steel increases bearing rigidity.

 

Low Torque-Low fricition,even without conventional lubrication,with extremely find surface finishes.

 

Long Wear Life-High Hardness of Rc78 greatly extends bearing wear characteristics.

 

Light Weight-60% Lighter than steel, reducing centrifugal forces and overall system weight.

 

Special Properties-All ceramic components are:

                                    -  Non Magnetic

                                    -  Electrically non conductive

 

 

Precision thin section Bearings

 

 

Precision Thin Section Bearings Are Special

Our Thin wall series are manufactured to industry standard sizes. The bearing widths and sections (distance from bore to outside diameter)in each series remains constant regardless of the change in bore diameter.

 

Inspection

Due to the large diameters and thin sections of these bearing products, it is necessary to address measurement and inspection techniques. To accurately measure the bore and outside diameters of thin section bearings, a specific procedure must be allowed.

 

Appropriate measuring equipment must be used which will allow the inspector to take 3 to 5 readings around the circumfence which are then averaged to determine the true measurement of the bearing in the free state (unmounted). This procedure allows for the inherent out-of-roundness these bearings will exhibit.

 

When measuring these bearings, special care must be excecised to ensure neither the bearing weight or pressure from the measuing equipment affects the measurements.

 

Installation

If thin section bearings are being installed into a housing, pressure should be applied only on the ourter ring. Bearings to be installed on a shaft should be pushed on the inner ring. Since the majority of thin bearings are open(without seals), a clean, contaminant-free installation area is advised.

 

Lubrciation

Rolling element anti-fiction bearings rely on ball and raceway surface lubrication. A thin film of oil or grease should be used. Be sure not to contaminate the lubricant used in the bearings, Our standard OPEN (Unsealed) bearing are shipped with only a light oil as a corrossion inhibtor. You must lubricate these bearings with the appropriate grease or oil for your application. Sealed Bearings are shipped as standard practice with 20%-30% fill of MilG-81322 grease.

 

Load Bearing

Information listed in our catalog such as load ratings and bearing dimensional data has been complied from industry standard data as well as as ABMA and ANSI information and formulas. Technical Information have been modified from us. Load capacities show in the catalogue are not additive. For combined radial and axial loading an equivalent radial loading must be calculated.

 

Housing & Shaft Fits

Thin section ball bearings are affected by the tolerances,roundness, and expansion & contraction rates of the housing & bearings. The "precision tolerances & Recommended Fit" shown in this catalogue are for bearings with standard diametral clearance and steel shaft & housings. Bearings with special clearance or preloads and those which are mounted in, or have shafts in, material other than steel, will need special internal clearance consideration to account for different expansion & contraction rates of dissimilar material.
