The keyless connection structure allows the inner and outer sleeves to shrink and expand under axial force, creating a tight fit between the shaft and hub. This generates enough friction to transmit torque efficiently, ensuring smooth operation.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBore Diameters\u003c\/td\u003e\n\u003ctd\u003e24 x 50 mm (0.94\" x 1.97\") to 50 x 90 mm (1.97\" x 3.54\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Numbers\u003c\/td\u003e\n\u003ctd\u003eSTK603, TLK603, RCK19, SD71, SCD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStructure Type\u003c\/td\u003e\n\u003ctd\u003eKeyless Connection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eCNC Tooling, Shaft Locking, Industrial Machinery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eHigh-Strength Alloy Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurface Treatment\u003c\/td\u003e\n\u003ctd\u003eAnti-corrosion Coating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTorque Transmission\u003c\/td\u003e\n\u003ctd\u003eHigh Torque Capacity\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eWe offer a wide range of sizes.
