If a wheel or caster is exposed to mainly static loads, its static load capacity is tested in accordance with ISO 22878. One of the criteria that this test looks at is the extent to which the tread flattens after a specific period. Information about the static load capacity of our products is available in our product data sheets.
ادامه مطلبUnder normal load and operating conditions: f.s = 1-2 Under impact load or vibration operating conditions: f.s = 2-3 For best dynamic performance and service life, aim for a f.s >5. Dynamic load capacity is not a stand-alone load rating, but rather a parameter used in an equation to calculate the theoretical service life of a bearing system. It ...
ادامه مطلبSo, if the dynamic load rating is 80 kg then the static load rating is deemed to be 240 kg (80 kg x 3). In the case of our roof top tent scenario then you will have 100 kg left for your mattress, pillows, linen and …
ادامه مطلبDynamic Load A dynamic load refers to the weight that is placed on an object and then put in motion. For example, a pallet rated for a dynamic load of 2000 lbs means you can put up to 2000 lbs. of an evenly distributed product on the pallet. Then the pallet could be placed on a conveyor system or be moved around a warehouse by a forklift.
ادامه مطلبOnce the combined static load has been calculated, it can be used to determine the static load safety factor. The static load safety factor is calculated by dividing the basic static load rating (C 0) by the static equivalent load of the most heavily loaded bearing.The recommended safety factor is given by the manufacturer, based on the type of loading …

ادامه مطلبOnce the car is parked, that dynamic weight rating becomes a static weight rating. The static weight rating is roughly 5-7x the dynamic weight rating of the crossbars (while you are sleeping in the tent). This gives you plenty of excess capacity to start piling in the tent for a good night's sleep once you hit the campsite.
ادامه مطلبThe load can be either dynamic or static, and in some cases, springs may experience one or the other, or both! A static load is a fixed load or a force applied gradually. For example, a spring that is simply holding something would be considered a static load. However, once the spring starts moving, it would be considered a dynamic load for it ...

ادامه مطلبThe spring system allows transmis-sion of no more than 10 percent of the dynamic loads from the crusher into the supporting structure – keeping it nearly vibration-free.
ادامه مطلبStatic load capacity, C 0, is the amount of load a bearing can withstand before the sum of the ball and raceway deformation equals 0.01 percent of (0.0001 times) the ball diameter, as defined by ISO 14728-2.Static load capacity is almost always higher than dynamic load capacity because its limitation is plastic deformation of the ball and raceway material, …
