The flat plate interface is used to connect a mounting block onto a flat surface. This is the simplest method to make this assembly, but it prevents lateral motion only against small (10% of the total load) side loads, so is only recommended for gravity applications.

The pocket interface is used to connect a mounting block onto a surface while preventing lateral motion against side loads as high as the full load. This interface is recommended for tilting and dynamic applications.

Blind retainers are used to constrain the Spherolinder from tilting too far while in the V-groove, and preventing it from being removed or flipped in place. They should be used in gravity or small-tilt applications, since they do not secure or preload the two mating components to each other.

Assembly steps:
- Place the Spherolinder in V-Groove.
- Insert the retainer through Spherolinder and V-block with the Allen head end trailing.
- Apply Loctite compound to the bottom thread of the retainer.
- Secure retainer in place with the nut while holding the retainer using an Allen wrench.
- Confirm that the Spherolinder is free to move and tilt about 1 mm.
- Optionally, thread the alignment guides at the top of the retainer.
- After all 3 retainers are assembled, the second component (with C-blocks) can be placed on top of the Spherolinders.
Through retainers are used to constrain the Spherolinder from tilting too far while in the V-groove, preventing it from being removed or flipped in place, and securing and preloading the two mated components to each other.

Assembly steps:
- Assemble 3 retainers in the same way as blind retainers.
- After all 3 are in place, place the second component (with C-blocks) on top of the first.
- Place all Belleville stacks in place - pay attention to the washers' orientation.
- Apply Loctite compound to the top thread of the retainer.
- close top nuts until they make solid contact with the Belleville stack.
- For 180° tilt application, continue to tighten the nuts to the angle prescribed.
