Two-Inch Shaft Collar

The Climax Metal Products 2C-200 is a two-piece clamp-style shaft collar with a 2 in round bore. It is machined from 1211 carbon steel for general power-transmission mounting tasks. The split design allows installation or repositioning without sliding the collar over the shaft end. Carbon steel screws secure the two halves around the shaft.

Inch-Series Clamp Limits

The collar uses an inch-series bore and fastener system, so it fits shafts made to that standard only. Its 11/16 in width and 3 in outside diameter set the axial and radial envelope for attached components. The 3.31 in clearance diameter defines the space needed for the screw heads to rotate during tightening. Metric shafts or larger bores cannot be accommodated.

2 In Bore Capacity

The 2 in bore handles shafts of that exact diameter with the full clamping force of the two-piece design. Stepped shafts larger than 2 in at the mounting point will not pass through the bore. Shafts smaller than 2 in leave a gap that reduces holding power and concentricity. The 1211 carbon steel material provides standard strength for typical torque and axial loads.

Questions about this item

Should I choose the 2-piece clamp collar over a 1-piece version for a 2 in shaft?

The 2-piece design clamps around a 2 in shaft without sliding it over the end, saving teardown time on installed equipment.

What does the 3.31 in clearance diameter mean once the collar is mounted?

It sets the minimum space the collar occupies radially, so adjacent parts must clear a 3.31 in circle around the shaft centreline.

How does the 11/16 in width affect clamping force on the shaft?

The 11/16 in wide carbon-steel band distributes the screw load evenly, giving a uniform grip on the 2 in bore without marring the surface.
