Climax Metal Products MC-38-S Metric Set Screw Collar Transparent

What this collar is and who uses it

The Climax Metal Products MC-38-S is a metric set-screw collar supplied in a transparent finish. It belongs to the bearings, V-belts and power-transmission equipment range and is sold new. Industrial maintenance teams and machinery builders use it to lock components onto metric shafts. Buyers who need a different bore size, a split-clamp design or a non-transparent material cannot use this part.

Behaviour under sustained load

The collar secures a shaft by tightening a single set screw against the metal surface. Holding force depends on screw torque, shaft hardness and the presence of a keyway or flat. Vibration, thermal cycling or axial shock can reduce clamping effectiveness over time. No load-rating, speed limit or temperature range is published by the manufacturer for this model.

What to verify before ordering

Confirm that the shaft diameter matches the 38 mm bore implied by the model code. Check that a set-screw locking method is acceptable for your application and that the transparent material meets any chemical-exposure requirements. Review the California Proposition 65 warnings for cancer and reproductive-harm substances. Ensure the order value reaches 75 if you require manufacturer-direct shipping with no extra charge.
