We focus on what is largely required in cutting copper and stainless steel tubes at the product design stage. Most importantly the cutting wheel must rotate straight to complete cutting. The cutter must also rotate around the pipe smoothly. For this reason, MCC installed 6 (six) individually sealed stainless steel ball bearings on the frame and 1 (one) needle bearing in the cutting wheel. This sounds like an unusual application of ball bearings; however once you take a look at the wheels of some of your carts in the warehouse, you will discover bearings on slower revolving parts such the casters where the wheels are attached. Under a high amount of weight and pressure, ball bearings are of great assistance. Tubing Cutters work in the same way. When your tubing cutters are new, you might hardly notice the difference between MCC tubing cutters and an ordinary pair of cutters that do not have a bearing installed. However, after one month of use, you will clearly notice the difference between the two cutters.
