(2) Smooter motion Improved steel ball circulation stability, free of interference between te balls improves dynamic friction caracteristics, resulting in smoot and stable motion, wic is especially effective for low speed motion. (3) ow dust generation resin retaining piece, wic prevents steel balls collision, features effective low dust generation caracteristics compared to conventional products. (4) ig self-aligning capability (rolling direction) Same as te D combination in angular contact bearings, self-aligning capability is ig because te cross point of te contact lines of balls and grooves comes inside, reducing moment rigidity. is increases te capacity to absorb errors in installation. (5) ig load carrying capacity to vertical direction e contact angle is set at 50 degrees, increasing load carrying capacity as well as rigidity in vertical direction. (6) ig resistance against impact load e bottom ball groove is formed in te 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 rows, were balls are contacting at two points. ecause of tis design, te bottom 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. 139 (7) 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.

(3) ow dust generation resin retaining piece, wic prevents steel balls collision, features effective low dust generation caracteristics compared to conventional products. (4) ig self-aligning capability (rolling direction) Same as te D combination in angular contact bearings, self-aligning capability is ig because te cross point of te contact lines of balls and grooves comes inside, reducing moment rigidity. is increases te capacity to absorb errors in installation. (5) ig load carrying capacity to vertical direction e contact angle is set at 50 degrees, increasing load carrying capacity as well as rigidity in vertical direction. (6) ig resistance against impact load e bottom ball groove is formed in te 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 rows, at were balls are contacting at two points. ecause of tis design, te bottom 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.
