3-inch casters (PU Lee rubber wheel nylon wheel wheel mute)

Wheel selection: Industrial castors single round variety, do not want in the size, type, tread, etc. with. Select the appropriate wheel to take on the following conditions: A weight-bearing B C using special climate space environment, such as humidity, heat or cold. D work environments containing chemicals, blood, grease, oil, salt and other substances. E impact, collision and travel tranquil requirements. Single round is to determine the carrying capacity and with flexible light most important factor. Characteristics of wheel material: compressive strength: compression test, the sample is exposed to the maximum compressive stress in money MPa units. Hardness: used to measure the hardness of rubber and other tire and wheel core material with a Shore "A" or "D" to represent. Elongation: the role of tension between the specimen break marking the distance to increase the amount and ratio of the initial gauge length, expressed as a percentage. Impact strength: The material to withstand the impact of free fall performance violent weights applied. Inches / lb, ft / lb test punching power temperature can be represented. Under the weight of anti-deformation: in a long time under the wheels of heavy change into flat place that test samples withstand certain static load, after a predetermined time after the end of the compression load shed, son of the place changed after the table height compared to the percentage of its original height. Operating temperature: measuring the operating temperature range rated load. Adhesion: at 6 inches / minute speed the tire from the wheel core bonded on top of the force required to peel off, in pounds divided by the line width of the tire is calculated. Tensile strength: the wheels when needed to break away from the transverse cross-sectional force. In pounds divided by the sample cross-carrier then Area (square inches). Water absorption: Test sample weight increases. The percentage of a particular procedure after the initial weight of the test weight is represented by the sample. Anti-wrapped piece cover: to prevent and other materials wound bracket and wheel axle and a gap, so that the wheels can rotate freely. Seals: Avoid steering wheel bearing into the bearing or single dust to maintain its lubricating properties to facilitate rotation. To lock: By the spring latch to lock the steering bearing (four or two locking), Caster can be locked to a fixed casters. Single wheel brake catch: the sleeve mounted on the wheel or tire surfaces, hand or foot operated brake catch device. Full brake catch: it can in the Transportation below can make it in a fixed position on the apparatus. Other: includes a steering arm lever, rubber fender, locking pads and other parts for specific purposes. There is a need, please contact! Tel: 0531-88638525
