BEARINGS
SEALED BALL BEARING
Use Peer bearings or equivalent for YeloRoll ® Conveyor Rollers.
Peer Ball Bearings
|
Peer 6205-C3 Deep Groove Ball Bearings with 50% Grease Fill |
|
|
|
The narrow path of the balls allows for constant contact with grease for the life of the bearings. Grease is held in close contact with the bearing balls by the bearing manufacturer's seal running on a polished surface. |
TAPERED ROLLER BEARINGS
|
|
The grease running action caused by the surface of the roller bearing forces the grease to the outside of the bearing with no way of replacing except to re-grease. Grease is held in place only by the idler manufacturer's seals which often leak and are usually located at a much greater distance from the bearing than the seals on a sealed ball bearing. |
IF YOU INTEND TO GREASE, BUY TAPERED ROLLERS, IF NOT, BUY YELOROLL ® CONVEYOR ROLL FACTORY SEALED BALL BEARINGS.
SEALED BALL vs. TAPERED ROLLER BEARING
BEARING MISALIGNMENT
|
BALL BEARING Single row deep groove ball bearings with C4 clearances will allow up to 16 minutes of angular deflections while still maintaining normal contact. |
|
|
|
NORMAL CONTACT |
TAPER ROLLER BEARINGS
Taper roller bearings only tolerate 2 to 4 minutes of angular deflection. Angular deflection caused by heavy loading creates edge only contact of the roller bearings severely reducing bearing life.
