50mm diameter spring loaded zinc-plated steel conveyor rollers

50mm diameter spring loaded zinc-plated steel conveyor rollers HuaYun brand zinc-plated steel conveyor rollers have been certificated by the TUV, ISO9001/2008 and Safety  Certificate for Mining Products. With high quality and competitive prices, our products enjoy a good  reputation both in home and the abroad. 1.Detail show for the spring loaded zinc-plated steel conveyor rollers   Features of gravity conveyor rollers:  a. The precision ball bearing is fixed by impact in the steel housing, tight and durable. b. The tight steel bearing unit could bear more axial force than plastic bearing unit. c. Make it possible for the roller to work in the high or low termperature beyond the plastic part bear( e.g. oven or cold storage) d. Completer series of diameter, wide range of load capacity. e. Its noise is a bit louder, compared with 1200 series with polymer bearing unit g. Temperature range: -10 to +80  centigrade degree.

      Advantage of zinc-plated steel conveyor rollers: Zinc-plated is the most popolar suface treatment. The surface is electroplated through electrolysis, resulted in the rustproof in a certain extent. 1. Trivalent chromium blue-white zinc-plated, conformed to the requirement fo environmental protection. Special sealing process make our zinc-plated much more rustproof than common one, especially in the salt spray testing. 2.  The suitalge thickness of zinc layer for roller is 8-12μm. If zinc layer is too thin, the rustproof capacity is lowered greatly; but if took thick, the zinc lay is easy spalling, and it brings meaningless cost increase. 3. The rustproof capacity of zinc-plated is limited. It will decay quickly in the moist and acid-base environment. In the case of roller shipment by sea, specially packing for shipment by sea is still needed. 4. Zinc-plated is not of strong abrasion resistance. It will fray gradually in the operation. If needed, you could choose the hard chrome plating or other surface treatment. 5. Food is not allowed to contact directly with zinc-plated surface.   2. Here are some types of conveyor rollers we made. 1) female thread gravity conveyor rollers 2) Sprocket drive conveyor rollers 3) PVC graivty conveyor rollers   Advantages of HuaYun manufactured gravity conveyor rollers  (1)Easy installation and nice flexibility; (2)Low friction coefficient; (3)Dust- and water-proof;  (4)Fine welding technique ensure roller with low vibration and noise;  (5)Electrostatic spraying technic makes the roller more durable and good-looking; (6)Strict inspection standard ensures our high quality product.   3. Besides we can manufacture the conveyor rollers and conveyor idlers according to the buyers' requirements 4. Comprehensive and rigorous quality control is our speciality:   5. Packaging:       6.
