This series are suitable for middle duty conveying.
Advantages:
Based on the B212/B213series design, covered with polypropylene(PP)tapered sleeve, abrasion resistance, low noise, shockproof, not influenced by change of temperature and climate. As sprocket made of Polyamide(popularly named Polymer Sprocket)as the driving element, the running noise is greatly lowed down compared with steel sprocket. Precision ball bearing polymer bearing housing, end cap form the bearing unit whlch is very important, it is not only for good looking but also further more for the smooth and quiet running. The covering of the end of rolIer, well dust proof and water splash proof in operation environment.
Disadvantages:
Cause the material is polymer,it can' t be used in the high temperature environment.
