This bearing block can hold a ball bearing with 21mm diameter. It is held by 2 knurled screw size M2. It is recommended to reinforce the thread for the knurled screw with an insert nut.
Furthermore it is possible to fix the bearing block on a wooden plate or similar by means of 4 countersunk screws of the size M2.
I designed this bearing block to make my own arrows for my bow.
I would be pleased about feedback.
