Severe service locations where grease-less Poly-Round® bearings are well-suited:
- high or low temperatures
- submerged (water, chemicals, processing fluids)
- washdown
- steam
- oscillating motion
- frequent start-stop cycles
- impact or vibration
- high load
- difficult-to-maintain locations
- jack shafts with center bearings
|
APPLICATIONS TO AVOID
Plane bearings are not recommended for:
- high speed devices (fans, pumps, table top conveyors)
- high tension applications (V-belt drives, flat belt conveyors, urethane belts)
- overhung loads (shaft mounted gear reducers)
- trunnion applications
|
|
For locations where plane bearings are not recommended, choose a ball bearing (one-piece, not a split insert).
|
|
EDT offers:
|
stainless ball bearings
|
- regreasable
- solid lubricated (choice of two solid lubricants depending on application)
|
| |
standard ball bearings
|
- large shaft size units that are corrosion-resistant and solid lubricated
- solid lubricated for hot, dry locations (ie: ovens not subject to washdown)
|
MATERIAL SELECTION CHART
(1) PV limits are shown for unlubricated radial bearing applications.
Low temperature and/or cool submerged installations may permit PV limits
up to 2x higher. For high ambient temperatures including warm submerged installations,
calculated PV’s must be reduced.
