The ring attached to the shaft is called the inner ring or tight washer and the ring attached tothe housing is called the outer ring or loose washer. In double direction Thrust ball Bearings thereare three rings, with the center ring fixed to the shaft. Single direction Thrust ball Bearings cansupport axial loads in one direction only; double direction, in two.

3 Both are available with analigning seat and washer beneath the outer ring to compensate for shaft misalignment or roller Thrustbearings have a spherical raceway in the outer ring with the rollersdiagonally arranged in a single row. These Bearings have a very high axial load capacity and arecapable of taking moderate radial loads when an axial load is imposed. Because of theconfiguration of their rolling elements, spherical roller Thrust Bearings are capable of handlingmisalignment and are suited for moderate speed BearingsIntroductionBallBearingsSpherica lRoller BearingsTaperedRoller BearingsThrustBearingsSplitPillowBlocksS uper PrecisionBearingsRolling MillBearingsLinearMotionEngineeringSecti on139 Nomenclature Ball Thrust BearingsInterchange Ball Thrust BearingsDESCRIPTIONINTERCHANGENSKSKFFAGS INGLE DIRECTION511xx511xx511xxSINGLE DIRECTION512xx512xx512xxSINGLE DIRECTION513xx513xx513xxSINGLE DIRECTION514xx514xx514xxSINGLE DIRECTION WITH ALIGNING SEAT532xx532xx532xxSINGLE DIRECTION WITH ALIGNING SEAT533xx533xx533xxSINGLE

Also available, but not shown,are cylindrical roller Thrust Bearings (TMP) and tapered roller Thrust Bearings (TT, TTF or V-Flat).Please consult an NSK representative for more information. The ball Thrust Bearings are designed to handle Thrust loads while operating at high Bearings can be ordered with an aligning seat and aligning washer if misalignment ordeflection can not be spherical Thrust Bearings are designed to handle very heavy Thrust loads in one directionwhile operating at low to moderate speeds.

7 The design of the spherical Thrust will also allow forsome radial load while Thrust load is imposed.
