Ruland Manufacturing MSP-35-F 2-piece shaft collar 35 mm bore 57 mm OD 15 mm wide carbon steel

Precision shaft collar for 35 mm shafts

The Ruland MSP-35-F is a two-piece clamp collar machined from 1215-grade carbon steel. It fits a 35 mm round bore and provides a 57 mm outside diameter with a 15 mm width. Alloy-steel screws secure the split design around the shaft without marring the surface. The collar suits metric-system machinery where a removable, reusable axial stop or component mount is required.

Thermal and power behaviour in normal use

As a passive mechanical fastener the collar generates no heat and draws no electrical power. Operation is silent because there are no moving parts, fans or fluid circuits. The carbon-steel body simply clamps in place and remains at ambient temperature during typical indexing or light-duty holding tasks. No thermal management or power budget is needed.

Behaviour under sustained load

The two-piece construction maintains clamping force over long periods without the stress relaxation that can affect single-piece rings. Alloy-steel screws resist creep so the 62.4 mm clearance diameter stays consistent under continuous axial or radial loading. The collar is not intended for applications that demand a keyway, threaded bore or a different material grade such as stainless steel.
