how to convert varchar to int

there is a varchar column named emp_ref_no and it's length 20, I tried to convert it into int

select cast(emp_ref_no as int)
from tables
where isnumeric( emp_ref_no ) =1

however I got error message:

The conversion of the varchar value '133261280299' overflowed an int column. Maximum integer value exceeded.

Is anyone can help? many thanks
