Product Description

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.

1. Based on the 2224 Series, covered with grey polypropylene taper sleeve; abrasion resistant, low noise, shockproof.
2. Using the polyamide sprocket roller as the drive element reduces the running noise.
3. The bearing end cap consists of a precision ball bearing, a polymer housing and end cap seal. Combined they provide an attractive, smooth and quite running roller.
4. The design of the end cap protects the bearings by providing excellent resistance to dust and splashed water.
5. To avoid abrasion between the sprocket and chain, the angle between tapered rollers should not exceed 5°.
