SWC Series Industrial Drive Shaft Spline Sleeve & Shaft Assembly

Heavy-Duty Telescopic Spline Sleeve & Shaft Bar Components for Universal Joint Couplings

The SWC Series Industrial Drive Shaft Spline Sleeve & Spline Shaft Assembly is a high-precision, heavy-duty mechanical transmission component designed for industrial motors, metallurgical equipment, and telescopic Cardan drive shafts. Precision-forged from premium 40Cr and 42CrMo alloy steel, these spline components feature high torque load limits, high concentricity, and exceptional wear resistance. Engineered with strictly controlled module, tooth count, and induction-hardened spline teeth, the SWC spline sleeve and bar assembly accommodates smooth axial displacement while transmitting massive dynamic power without backlash or rotational delay.

Key Advantages & Features

• Premium Forged Alloy Steel Construction: Manufactured from high-grade 40Cr and 42CrMo alloy steel forgings, offering superior core toughness, fatigue resistance, and shock absorption.
• Advanced Heat Treatment & Hardening: Undergoes quenching and tempering (HB 220–300 core hardness) with precision induction case-hardening on spline teeth (HRC 50–55, 5–6 mm penetration layer) for long-term wear resistance.
• Telescopic Axial Movement Compensation: Precision-machined internal and external splines allow smooth, low-friction sliding compensation for dynamic axial length changes during heavy equipment operation.
• Extensive Model Range: Covers a full range of standard industrial sizes including SWC120, SWC250, and SWC440 series spline sleeves, spline shafts, and spline yokes.
• High Torque & Zero Backlash: Precision CNC broached internal teeth and ground external splines ensure tight mesh engagement, minimal vibration, and maximum operational stability.
• Non-Standard Engineering Customization: Customizable outer diameters, total lengths, weld interface diameters, tooth modules, and tooth counts based on client drawings.

Technical Specifications

Applications & Machinery Compatibility

The SWC industrial spline sleeve and shaft assemblies are core load-bearing components widely used in heavy transmission lines, including:
