(2) ig load carrying capacity to vertical direction e contact angle is set at 50 degrees, and tus increasing load carrying capacity as well as rigidity in vertical direction. (3) ig resistance against impact load e bottom ball groove is formed in otic arc and te center of te top and bottom grooves are offset as sown in ig. 2. e vertical load is generally carried by te top ball rows, were balls are contacting at two points. ecause of tis design, te bottom ball rows will carry load wen a large impact load is applied vertically as sown in ig. 3. is assures ig resistance to te impact load. (4) ig accuracy s sowing in ig. 4, fixing te master rollers to te ball grooves is easy tanks to te otic arc groove. is makes easy and accurate measuring of ball grooves.

(2) ig load carrying capacity to vertical direction e contact angle is set at 50 degrees, and tus increasing load carrying capacity as well as rigidity against te load in vertical direction. (3) ig resistance against impact load e bottom ball groove is formed in otic arc and te center of te top and bottom grooves are offset as sown in ig. 2. e vertical load is usually carried by top 2 rows, were balls are contacting at two points. ecause of tis design, te bottom rows will carry te load wen a large impact load is applied as sown in ig. 3. is assures ig resistance to te impact load. (4) ig accuracy s sowing in ig. 4, fixing te measuring rollers to te ball grooves is simple tanks to te otic arc groove. is makes easy and accurate measuring of ball grooves.
