Each of the two rows has a 30 Contact construction, or C-type, Double-Row ballbearings have Contact angles that converge outside the bearing, thereby increasing resistance tomisalignment. This type does not have filling bearings are recommended for applicationswhere single-row ball bearings are inadequate, butradial loads are not so great as to suggest a filling-notch bearing. They will take heavy radial loads andaxial loads equally in either direction. The C-typedesign fully meets the requirements of AmericanPetroleum Institute (API) Specification the inner and the outer rings have closuregrooves.

2 These bearings are available with seals,shields, and capacity Double-Row ball bearings have fillingnotches on one side to permit assembling themaximum number of balls into the bearing. Contactangles converge outside the bearing. All inner andouter rings have closure grooves. These bearings maybe equipped with seals, shields, and snap-rings. TheM-type bearing has very heavy radial capacity. It alsohas thrust capacity in one direction, with the ability toaccommodate light thrust load in the numbers on M-type Double-Row bearings arenormally located on either the side face or the of the side face marking is alwayson the side opposite the filling notch and the is offset from the center away from the fillingnotch.

3 These old-style5000 type double-rows were available in the SBConrad and maximum capacity configurations. The SB Conrad version had Contact angles whichdiverged inwardly, thereby increasing resistance to misalignment. The maximum capacity versionhad Contact angles which converged inwardly,giving it the capability of handling small amounts of misalignment. It also had filling notches on both sides, for the introduction of a maximumcomplement of Double-Row ball bearings are available in the C-type (Conrad construction) and M-type (withfilling notches on one side only). Both types featureinwardly diverging Contact angles, which providegreater rigidity than found in the previous Double-Row filling-notch type bearings. A uniquemanufacturing system utilizing common parts isemployed in the manufacture of these a minimum number of components, thesystem provides greater flexibility for producingeither Conrad or maximum capacity types as openbearings or with a variety of closures.

Axial load should be carried on the non-filling notchrow. A moderate reversing axial load is permissible on the filling notch filling notch is oriented in relation to theidentification marking on the bearing, which will befound in one of the following locations: Side face of the outer ring Side face of the inner ring OD surface of the outer ring Face of the closureIn each case the marking will occur on the side of thebearing opposite the filling notch as illustrated typical application of a 5000 MFF or 5000 MZZbearing is shown above in which it is subjected to anaxial load in an upward direction.
