Shaft Collars Wedge TypeMechanism and Clamping Force Data / Wedge Type Lineup and Advantages

QDefinition of Max. Thrust LoadThe shaft collar is tightened to torque value shown in the chart below, then compressive load is applied with the tester. The compressive load where the shaft begins to move is defined as the Max. Thrust Load.

QTesting Conditions1. Shaft: MISUMI Hardened Shaft (SFJ) P.1012. Testing Instrument: Universal Tester3. Tightening Torque: Select Tightening Torque from the tables on the left depending on the conditions of use.4. Condition of Antirust Oil: Wiped with a cloth as arrived.

QFeature: Post assembly collar installation makes maintenance easier compared to Set Screw Type (P.241) and Clamp Type (P.243).

QWedge Type Lineup• 24 types are offered including 6 shapes, 2 kinds of levers and 3 materials in combination.

QAdvantages of 2-Hole / 2-Tapped / 3-Hole / 3-Tapped Type• Unlike Clamp Type, assembly procedure is not limited.

QAdvantages of Compact, Clamp Lever Type• Smaller by up to 30% in O.D. and 22% in width than Standard Clamp Lever Clamp Type.

Tighten Screw1 first and then, tighten Screw2 finally. If Screw2 is tightened first, it may become much harder to clamp the shaft securely.

QWedge Mechanism Feature· The screws pull a wedge and the shaft is clamped; this structure requires less force for tightening.

· Good work efficiency; suitable for use in frequent positioning adjustments like width guide applications. The wedge for "Clamp Lever Type" (P.248) is made of brass and does not damage shafts.
