What is the castor
Some many people was the first time heard that castor this name, but don't know what is castor. Castor is a product's name, because this is a less popular industry product name. Caster and the main products are a mix of metal parts and plastic parts. On the need to move and ChengCheng under the weight of the product, which belong to product of form a complete set of parts. Castor parts: · the assembly: consists of the legs, shaft and nut. Do not include the wheel, wheel bearings and bushings. Bush: is a set of steel to the outside of the wheel and axle manufacturing of rotating parts. Set on the outside of the shaft, steel manufacturing of rotational parts, fixed wheels in stent for wheel bearing rotation. On the shaft sleeve with the axis of rotation. Rotating bearing: steering bearings have a number of different models, such as: single bearing: only a layer of steel ball big orbit, commonly known as single row ball bearing. Double bearing: also called double row ball bearing, in two different orbit, double ball. Economical bearing: the stamping forming of bead disc retainer on the ball. Precise bearing: the standard of industrial bearings. Rivet, center: a center of rivet is bottom of local, bolts or rivets for fixed rotating device. Can adjust screw down the bolt type rivet caused by rotation wear loose. The single wheel (, The wheel) Single wheel material performance parameters, hardness: used for measurement of rubber and other tire and wheel core material hardness, with shaw represented 'A' or 'D'. Compression strength: in the process of the compression test, the sample on the maximum compressive stress, mpa to bill for the unit. Elongation: under the action of tension, the sample fracture line when the distance between the increase and the ratio of the initial range, expressed as a percentage. Impact strength: data receiving free falling weight imposed by the onslaught of performance. Inch/pound, ft/LBS or test temperature stamping work. Under pressure, the deformation resistance: long time under the weight of the wheels with place larger flatten, absorb a certain amount of static load test sample, and then at the end of the compression time stated on the discharge load, the height of the wheel with location become table after compared with the original high percentage. Working temperature: measurement under the rated load to the working temperature range. Water absorption. The increase of the test sample weight with the weight of the sample after a particular order test and the initial weight percentage said. Metal metal (test data V - Slot wheel) Hard rubber adhesion of polyolefin soft tire rubber/rubber adhesive package narrow face of synthetic rubber, polyurethane adhesive package of synthetic polyurethane enhanced thermosetting plastic tensile strength: the wheel from the required force when the cross section is broken. In pounds divided by the number of samples for the unit cross-sectional area ( Square inch) Adhesive force: 6 inch/min speed glue the tire from the wheel core of stripping force needed for above, divided by the straight line width tires for the unit with the pound. Accessories: a single wheel brake switch: on the wheel axle sleeve or tire surface, controls the brake switch device with hands or feet. Seal: prevent bearing or bearing of single wheel into dust, maintain its lubricity, easy to turn. Anti-wind cover: to prevent and other sundry wrapped around the gap of shaft and support with wheels. To rotate the wheels can be free. Brace: device under the transportation, can make its fixed at a particular location on the device. Others include steering arm, leverage, rubber fenders, locking pad and other spare parts with a specific purpose. The brake switch: can lock steering device can be fixed wheel brake button again. Steering lock: through the spring bolt locking to bearing ( Four or two locking) Fixed casters, caster wheel lock for the activity. For don't understand the specific use of spare parts, can be directly consulting manufacturers. Castor areas of application: mainly the medical industry, light industry manufacturing, logistics transportation equipment manufacturing industry, widely used kitchen utensils and kitchen equipment industry. The main production base mainly concentrated in zhejiang, guangdong and jiangsu area. Dosage the biggest area in the southeast coastal area. Product is classified according to the size and weight ChengCheng one or indicator of industrialization. The main supply industry for carton packaging industry, bearing industry, plastic raw materials, sheet metal industry, advertising design industry and screw standard parts industry, steel industry, etc. Plastic products of local material decided the use environment, decided to the size of the bearing series classification, therefore, has a professional product, according to the character of the industry use, use function will be different, therefore, the product line is very long. Must use the unit at the time of purchase, according to their own factories use environment, use frequency, using factors such as the required bearing weight, choose to suit your product type. Bottom plate and bearing: tablet device base plate used in device level. / news_46。
