NSK Spherical Roller Elevator Bearings 24028C

Spherical Roller Elevator Bearings Definition

Spherical roller bearing is in the article has two ways the inner circle and rolling rolling way for outer surface, between the drum assembly roller bearings.

Common characteristic

• Have two trains symmetric type spherical roller
• There is a Shared between the spherical groove
• Inner circle have two and Angle of the tilt a bearing axis groove
• Have good self-aligning performance

Have 2 Types according to Roller section shape

(2)asymmetric spherical roller

• mainly services for host maintenance
• Operating temperature is low so can adapt to a higher speed

Bearing should bear Certain minimum size of radial load, Press the type estimate :

Fr =0.02C

Fr -- Minimum radial load N

C— The basic dynamic load bearing rated N

Equivalent dynamic load  

P=Fr+Y1Fa  Fa/Fr e

P=0.67Fr+Y2Fa  Fa/Fr e

P— Equivalent dynamic load N

Y1 Y2—Axial moving load coefficient

Equivalent static load  

P0=Fr+Y0Fa

P0— Equivalent static load N

Y0—Static thrust load
