2-Piece 16 mm Bore Shaft Collar

This two-piece carbon-steel collar clamps onto a 16 mm round shaft without removing mounted components. The 1215 lead-free steel body has a black-oxide finish and measures 34 mm outside diameter by 13 mm wide. It suits maintenance tasks where a one-piece collar cannot be slipped over existing hardware.

Clamp-Style Installation and Clearance

The split design lets technicians position the collar around the shaft and tighten the alloy-steel screws for a secure grip. A 39.3 mm clearance diameter provides room for the screw heads during tightening. Over-torquing the screws can distort the bore and reduce holding power on the shaft.

Sustained-Load Behaviour

Under continuous radial load the two-piece construction maintains clamping force through the alloy-steel fasteners. The carbon-steel body resists deformation during prolonged operation. The black-oxide coating offers limited corrosion resistance in dry environments. California Proposition 65 warnings apply for cancer and reproductive-harm substances.

Questions about this item

How can I confirm the 16 mm bore collar is seated correctly on the shaft after tightening?

The 2-piece design lets you close the collar around the shaft; when the alloy-steel clamp screws are torqued the 34 mm outside diameter should sit flush and the 39.3 mm clearance diameter must not bind.

What components are included and what must I supply separately?

The box contains the two collar halves and the alloy-steel clamp screws; you provide the 16 mm shaft and any required tools.

When should I choose the 16 mm bore, 34 mm OD, 13 mm width version?

Select this version when the shaft diameter is 16 mm and the assembly space allows a 34 mm outside diameter with a 13 mm wide collar.
