Precision shaft collar for 13 mm metric shafts

The Ruland Manufacturing MSP-13-SS is a two-piece clamp-style collar machined from 303 stainless steel. It fits round bores of 13 mm diameter and provides a secure axial stop or component mount on precision shafts in metric machine builds.

Verify shaft diameter and clearance before ordering

Confirm the shaft measures exactly 13 mm round with no keyway, as the bore is plain. The collar outside diameter is 30 mm and the clearance diameter is 33.7 mm, so ensure adjacent parts allow this radial space. The 11 mm width must fit the available axial length.

Maintains clamp force under continuous vibration

The two-piece design distributes clamping pressure evenly around the 13 mm bore without marring the shaft. Stainless steel screws and 303 grade material resist corrosion and hold position during sustained operation, avoiding the loosening common with single-piece collars under cyclic loads.

Questions about this item

Does the 2-piece 303 stainless steel collar arrive with its clamp screws already fitted, or must they be purchased separately?

The collar is supplied as a complete 2-piece assembly with stainless steel screws installed; no extra hardware is required for mounting.

When should I choose the 13 mm bore version instead of a different bore size?

Select the 13 mm bore when the shaft you are clamping measures exactly 13 mm in diameter; other bore sizes are offered for shafts of different diameters.

How does the 33.7 mm clearance diameter affect installation on a 13 mm shaft?

The 33.7 mm clearance diameter is the space the open collar needs to pass over the shaft, so ensure adjacent components leave at least that much radial room.
