SWC150 Fork Yoke – Forged 45# Steel, 24 Teeth, 3 Module, Quenched & Tempered HB250-300

Factory Direct | Forged 45# Steel | 24 Teeth | 3 Module | Quenched & Tempered HB250-300 | Induction-Hardened Splines HRC50-55 | Precision-Machined | SWC150 Series | OEM Customizable

The Apexcoupling SWC150 Fork Yoke is a high-precision replacement component designed for SWC series cardan shafts and universal joint drive systems. Manufactured from premium forged 45# steel with a quenched and tempered heat treatment achieving HB250-300 hardness, this fork yoke delivers exceptional strength, wear resistance, and long service life in demanding heavy industrial applications.

The fork yoke (also known as a yoke head or fork head) is a critical component of the SWC cardan shaft assembly. It connects the cross shaft (spider) to the telescopic spline shaft, transmitting torque while allowing angular misalignment compensation. Featuring a 24-tooth, 3 module spline profile with induction-hardened spline channels (HRC50-55, 4-6mm case depth), this yoke ensures smooth, backlash-free engagement with the mating spline shaft. The SWC150 fork yoke is a direct replacement for worn components in SWC150 series cardan shafts, with full OEM customization support for custom dimensions and specifications.

✅ Premium forged 45# steel – high strength, excellent wear resistance. Quenched & tempered HB250-300 – optimal hardness and toughness. 24 teeth, 3 module – precision spline profile for smooth engagement. Induction-hardened splines HRC50-55, 4-6mm case depth – wear-resistant surface, extended service life. SWC150 series compatibility – direct replacement for worn yokes. OEM customization – custom dimensions and specifications available. ISO9001 certified manufacturing – quality assured.

Product Structure

1. Forged 45# Steel Yoke Body – Premium carbon steel, forged for optimal grain structure and material density, ensuring high strength and durability.

2. Cross Shaft Bearing Bores – Precision-machined bearing holes (55×128mm) for accurate cross shaft fit and extended bearing life.

3. Spline Bore (24 Teeth, 3 Module) – Precision-machined internal spline for engagement with the mating spline shaft.

4. Induction-Hardened Spline Channels – HRC50-55 hardness, 4-6mm case depth – wear-resistant surface prevents notched wear and extends service life.

5. Quenched & Tempered Treatment – HB250-300 hardness provides optimal balance of strength and toughness.

💡 How it works: The SWC150 fork yoke is a critical component of the cardan shaft assembly. It connects the cross shaft (spider) to the telescopic spline shaft, transmitting torque while allowing angular misalignment compensation. The yoke’s fork arms hold the cross shaft bearings, while the spline bore connects to the telescopic shaft. The forged steel construction provides the strength to withstand heavy shock loads, while the precision-machined bearing bores ensure smooth rotation and long service life. The induction-hardened spline channels (HRC50-55, 4-6mm case depth) provide a wear-resistant surface that prevents notched wear and extends service life.

Fork Yoke vs Yoke Assembly – Understanding the Component

The SWC cardan shaft uses multiple yoke components to enable universal joint function:

💡 The SWC150 fork yoke is the yoke component that connects the cross shaft to the telescopic spline shaft. It is available as a replacement part for worn or damaged yokes in SWC150 series cardan shafts.

FAQ

Q: What is a fork yoke?
A: A fork yoke (also called a yoke head or fork head) is a critical component of a cardan shaft that connects the cross shaft (spider) to the telescopic spline shaft. It transmits torque while allowing angular misalignment compensation.

Q: What material is used for the SWC150 fork yoke?
A: The SWC150 fork yoke is manufactured from forged 45# steel – a high-quality carbon steel offering excellent strength and wear resistance.

Q: What is the heat treatment?
A: The fork yoke undergoes quenching and tempering to achieve HB250-300 hardness – providing an optimal balance of strength and toughness.

Q: What is the spline specification?
A: The spline profile features 24 teeth with a 3 module. The spline channels are induction-hardened to HRC50-55 with a 4-6mm case depth for superior wear resistance.

Q: What are the cross shaft bearing dimensions?
A: The cross shaft bearing bore is 55 × 128 mm.

Q: What is the difference between a fork yoke and a flange yoke?
A: A fork yoke connects the cross shaft to the telescopic spline shaft via a spline bore. A flange yoke connects the cross shaft to the driven equipment via a flange face with bolt holes.

Q: Is this a replacement part for SWC150 cardan shafts?
A: Yes. The SWC150 fork yoke is a direct replacement for worn or damaged fork yokes in SWC150 series cardan shafts.

Q: Can I get a custom fork yoke?
A: Yes. We offer OEM customization – custom dimensions, materials, and specifications available.

Q: What is the warranty?
A: 1 Year – quality assured.
