cylindrical rollers can be manufactured to high levels of accuracy, depending on the specific application requirements. the accuracy of cylindrical rollers refers to how closely their actual dimensions match their specified dimensions.
high-accuracy cylindrical rollers are typically used in applications where precise motion or positioning is required.
we are professional manufacture of bearing rollers and cylindrical needle rollers. we produce rollers of diameter 0.5 mm to 60 mm. the rollers could satisfy the request of DIN 5402 G2 rollers.
needle roller contour surface in the proximal surface of the slight contraction. needle and raceway contact line results can be amended to avoid damaging the edge of the stress.
