Ruland MCL-50-F 50 mm Shaft Collar

This one-piece clamp collar fits a 50 mm round bore and is made from 1215 carbon steel with an alloy steel screw. It suits maintenance, repair and OEM applications where a secure axial stop is required on metric shafts.

19 mm Wide Steel Construction

The collar measures 78 mm outside diameter with an 84.7 mm clearance diameter and a 19 mm width. Its single-piece clamp design allows installation without shaft disassembly and the alloy steel screw provides strong holding force on the carbon steel body.

Metric Clamp Collar Limitations

The clamp relies on screw torque and shaft surface condition for grip; it may slip under high axial loads or vibration if not tightened to the correct specification. California Proposition 65 warnings apply because the steel contains listed chemicals.

Questions about this item

What is the bore diameter and collar width of the MCL-50-F shaft collar?

The bore diameter is 50 mm and the collar width is 19 mm, giving a precise fit on a 50 mm round shaft.

What are the outside diameter and clearance diameter for this one-piece collar?

The collar outside diameter is 78 mm and the clearance diameter is 84.7 mm, so the mounting space must accommodate at least 84.7 mm.

How is the MCL-50-F installed and what is the common mistake to avoid?

Loosen the alloy steel clamp screw, slide the 1-piece carbon steel collar onto the 50 mm shaft, position it, then tighten the screw; the common mistake is over-torquing the screw, which can damage the 1215 grade steel threads.
