Standard types of bearing
|
For many Interroll conveyor rollers there are various bearings available.
| Interroll bearing without ball retainer
This is a ball bearing developed by Interroll which has smoothly rolled race grooves, is of very simple design and has a comparatively high load capacity.
Compared with the precision ball bearing, the Interroll bearing is much less sensitive to potential bearing distortion. Alongside the precision ball bearing, this is the standard
bearing for Interroll conveyor rollers.
|
| Interroll bearing with ball retainer
The Interroll bearing with ball retainer can be used whenever a bearing is required that has to start up very easily. This bearing generates less running noise than the standard
version, but it also has a lower load capacity than the standard version.
|
| Interroll bearing made of stainless steel
This bearing can be compared with the Interroll bearing featuring a ball retainer. However, it is made entirely of stainless steel. On account of the non-corroding properties,
this version of the bearing has a lower load capacity.
|
| DIN precision ball bearing
This type of bearing is the standard DIN deep groove ball bearing in series 60 and 62. Precision ball race, maximum load capacities and service life, plus low-noise operation are
the outstanding advantages of this type of bearing.
|
| 2Z precision ball bearing
This type of bearing is identical to the precision ball bearing previously described. However, as an addition, it also has steel shields on both sides. These shields create a
narrow sealing gap and make no contact. That considerably improves the sealing of the bearing, and it is certain that the grease remains inside the bearing at high speeds.
|
| 2RS precision ball bearing
This type of bearing is identical to the precision ball bearing previously described. However, it additionally has neoprene seals on both sides, practically sealing the bearing
hermetically. The characteristics of this state-of-the-art seal will, however, affect the easy-running properties of the bearing to a certain extent.
