18 mm Metric Shaft Collar

The Ruland Manufacturing MCL-18-F is a one-piece clamp-style collar with an 18 mm plain bore. It is machined from black oxide 1215 lead-free steel and measures 36 mm in outside diameter with a 13 mm width.

Suits Metric Shafts Requiring Axial Location

This collar fits engineers and maintenance teams securing components on 18 mm metric shafts. It is not for applications needing inch-dimension bores, two-piece split designs, or different bore diameters.

18 mm Bore Diameter Decides Fit

The 18 mm bore diameter is the single specification that determines compatibility. Verify the shaft size exactly; no other dimension in the data substitutes for this measurement.

Questions about this item

Does the MCL-18-F shaft collar come with the M5 clamping screw or must it be purchased separately?

The collar is supplied as a single piece that includes the M5 alloy-steel clamping screw, so no separate fastener is required.

When should I choose the 18 mm bore version instead of another bore size?

Select the 18 mm bore when your shaft diameter is exactly 18 mm; the plain bore provides a precise slip fit for metric shafts of that size.

What does the 36 mm outside diameter mean for clearance inside my assembly?

The 36 mm outside diameter and 41.1 mm clearance diameter determine the minimum space needed around the collar so the clamp can be tightened without interference.
