Note:

n1 is No. of lube holes, the user can specify the lube hole position.
n-φ can be changed to threading holes, hole diameter M, thread depth 2M.
There are standard products in the catalog, and the inner and outer diameters are random tolerances. If there is a locating requirement for slewing bearing, please indicate the site and tolerance.
It is standard type of our products, if you need more please contact with engineer.
