● Common models

Lubrication:
1. It has good adhesion, is not easy to lose and leak; ⒉Long lubrication cycle, no need to add or replace grease.

Clearance: The clearance in the
bearing is to ensure that the bearing can run flexibly and without hindrance, but at the same time it is also required to ensure that the bearing runs smoothly, the axis of the bearing does not significantly sink, and the number of rolling elements that bear the load is as large as possible.
The bearing clearance suitable for conveying rollers is C3, which has good performance in ensuring the dynamic performance of the bearing (noise, vibration and friction), rotation accuracy and service life (wear and fatigue).

Sealing: The
purpose of bearing sealing is to prevent the leakage of lubricant inside the bearing, and to prevent foreign matter such as dust and moisture from entering the bearing, so as to ensure that the bearing may operate safely and lasting under the required conditions.
We recommend the use of RZ sealing method, which combines the advantages of RS and ZZ, has the same low friction characteristics as non-contact seal (ZZ), and at the same time has the same sealing and dustproof effect as contact seal (RS) .

According to the characteristics of the use of the barrel, we have configured different types of bearings for each product, and specified the clearance, lubrication and sealing methods.
