The maintenance of bearings is very important, there is also a very important step: import bearing packaging, what type of bearing packaging principles are different, such as: miniature bearings, small and medium-sized bearings are how to package and so on. The following I will explain to you the relevant aspects of knowledge, I hope it will help you. Bearing packaging principles are as follows:, extra-large bearings: single set of three-layer wrapping packaging; single multiplier four-layer wrapping packaging: the outermost layer and then wrap a layer of linen tape. For separable tapered roller bearings with outer diameter ≥ mm, the inner and outer components should be lined with polyethylene film before packing, or the inner and outer components should be packed separately. For the outer diameter ≥ mm interchangeable cylindrical roller bearings, because of the complete set of packaging is easy to knock, generally can be used inside and outside components are packaged separately. The large bearing: single set of polyethylene film or polyethylene composite paper packaging, and then into a carton; with polyethylene film bag, single set of packaging after folding the bag, and then into a carton; single set into a special plastic box; single set of three-layer wrapping packaging: inner layer with polyethylene film tape or composite paper tape, the middle layer with fastening tape, the outer layer with waterproof permeable plastic tape. Single set of bearings: multiple sets of bearings inside with polyethylene film, outside with kraft paper or polyethylene composite paper for roll packaging; multiple sets of bearings into a plastic tube (box); single set of bearings with polyethylene film bag packaging, fold or seal the bag mouth and then into a carton]. Miniature bearings: each ~ set of bearings into a plastic tube, each ~ plastic tube into a carton (or bag, roll package).
