hey mike, you can't buy just the front bearing from novak. Its the whole endbell and then a rear bearing in the same package. Novak claims that the front bearing is not removable. I ordered mine from tower hobbies. Novak part # 5919 or tower # lxmgj4 It says it for the 5.5 and 6.5 but the bearings are the same in the bl motors unless its an hv system which your's is not.
