TBB Bearing Technology introduced a bearing that it says will widen the selection for engineers when specifying for applications requiring high wear resistance, but that won’t crack under load.
Product type: Full complement cylindrical roller bearing
Application: Hook block and rope sheave of heavy load cranes, e.g. crawler canes, derrick cranes, port cranes

|
|
|
|
Competitive advantages of this product: |
|
|
|
Compact design: | Full complement design, small size, outer ring with snap ring, and split inner rings combined by locking ring |
High load, low speed: | Extremely high load capacity and rigidity due to the full complement rollers, |
| however, the bearing rotation speed can not reach as higher as normal cylindrical roller bearings. |
High quality sealing: | Dust and water proof, wear and aging resistance, suitable for outdoor use |
Accommodation: | Accommodation of axial tilting moments, suitable for extreme operating conditions |
