Metric Linear Bearings: Measurement Systems
Linear bearings may be measured and therefore pieced together according to two separate measurement systems, one of which is used exclusively in the United States. The US Customary measurement system involves inches, feet and yards, and is still taught in public schools and used as a common form of measurement in many industrial contexts. Alongside these measurements is the metric system, which is the standard in Europe as well as being common here. That is why metric linear bearings in fact make more sense, since they can translate in numerous countries, which is very helpful considering the amount of products that are bought in one country and used in another. If nothing else, it will make the purchase of replacement parts significantly easier.
The various models of linear bearings are all based on the same basic idea; to have two parts that are connected but need to be able to move smoothly apart and then together again, a system to do so with little friction or damage to the products is necessary. Linear bearings, whether they are measured according to the US Customary or Metric system, are set-up with balls or rollers within pre-set smooth ridges to create a pathway for stress-free movement.
Made of either metal or plastic, linear motion bearings are mechanical devices that may be customized for a variety of applications. Furniture such as moving bookcases, desks and dressers utilize them as do manufacturing, medical and robotic automation machines. The sizes and styles of linear bearings completely depend on the applications, which is why the measurements used depend on who is making them for whom. Fluidity is vital to ensuring that repetitive actions do not create expensive damages, and linear bearings monitor fluidity amongst machines in industry. Metric linear bearings have a better shot at being accessible in a number of countries, which makes them an even more applicable product on the market today.
