The most popular type of bearing in use today is the single row deep groove radial ball bearing.The basic function of a radial ball bearing is to transmit rotational motion without the loss of energy. To accomplish this, anti-friction bearings are generally composed of two SAE 52100 hardened steel rings separated by the balls and spaced by a retainer.The deep superfinished raceways make these bearings suitable for radial loads or a combination of radial and moderate thrust loads in either direction.This type of design combines high operating speeds and super precision tolerances. > The...

Radial internal clearance is defined as the internal space between the balls and rings of radial deep groove ball bearings.It is determined by design applications depending upon the temperature situations present, the amount of press fit, the bearing misalignment, noise level and speeds required. > The various tolerances and formulae used by the bearing industry today (through the efforts of the American Bearing Manufacturers Association, ABMA, and the International Standards Organization, ISO) have become nearly standard practice in bearing production.Therefore, except in isolated...

dmp, Vdp, Vdmp, Kia, Bs, VBS.And outer ring tolerances of Dmp, VDp, VDmp, Kea, cs, Vcs.See Tables 2 through 5.ABEC-5 specifies tolerances for the same characteristics as classes 1 and 3 with the addition of Sd and Sia for the inner ring and SD and Sea for the outer ring.See Tolerance DefinitionsӔfor an explanation ofthese symbols. To ensure dimensional accuracy in measurableforms, all PEER bearings are manufactured according to the ABMA established classes.These are currently listed as ABEC-1, 3, 5 and 7 for ball bearings.All standard production PEER bearings are manufactured to a minimum...

Choose a PEER bearing to be used for an application on the basis of its load carrying capacity in relation to theloads to be carried, its operation speed and the requirements regarding life and reliability.A numerical value termed BASIC LOAD RATING is used in the calculations to express the load carrying capacity.Values for the dynamic radial load rating (Cr) are shown on the bearing pages. 1)Basic Load Rating The basic load rating (Cr) is used for calculations involving dynamically stressed bearings, when selecting abearing which is to rotate under load.It expresses the bearing radial load...

Where P > 1 = constant load for t > 1 minutesP > 2 = constant load for t > 2 minutesP > n = constant load for t > n minutes 2.4 Static Load Rating In cases when the bearings are to rotate at relatively slow speeds, have slow oscillating movements, or areexposed to shock, the basic static load rating (Cor) must be taken into consideration. Bearing fatigue life can be adjusted for reliability, material and operating conditions through the following formula: Lhna = a 3.Adjusted Rating Life Calculations > 1 x a > 2 x a > 3 x L > h (hours) a > 1 , Life adjustment Factor for ReliabilityL > 10 is...

Oil is the basic lubricant for ball bearings.Previously most lubricating oil was refined from petroleum.Today, however, synthetic oils such as diesters, silicone and fluorocarbon compounds have found acceptance because of improvements in properties.Compared to petroleum base oils, diesters in general give better low temperature properties, lower volatility, and better temperature/viscosity characteristics.Silicones and fluorocarbon compounds possess an even lower volatility and wider temperature/viscosity properties. Virtually all oils contain additives that limit chemical changes, protect...
