Hebei Speed Torque Transmission Technology Co., Ltd. proudly introduces our Hardened Cross Bearing Kit for SWC Flange Universal Coupling – a premium spare unit engineered for demanding industrial environments. With over 7 years of experience in power transmission solutions, our factory spanning 3,000-5,000 square meters produces components that deliver exceptional wear resistance and reliable performance. This cross bearing kit is specifically designed to replace worn-out cross assemblies in SWC flange-type universal couplings, ensuring smooth torque transmission and extended equipment life.
Our cross bearing kits are manufactured using advanced heat treatment processes, resulting in a hardened surface that withstands high loads and repetitive motion. Each unit undergoes strict quality control to meet ISO9001 standards, guaranteeing consistent hardness and dimensional accuracy. Whether you operate in steel mills, marine propulsion, or heavy machinery, this spare unit offers a direct fit and improved durability over standard components.
Key Features & Technical Specifications
Material Excellence: Made from case-hardening alloy steel (20CrMnTi or equivalent), providing a tough core and wear-resistant surface.
Heat Treatment: Carburizing and quenching to achieve surface hardness of HRC 58-62, with depth of 1.0-1.5mm.
Precision Machining: CNC ground bearing journals with tolerance within IT6, ensuring minimal radial play and vibration.
Compatibility: Direct replacement for SWC-225, SWC-250, SWC-285, SWC-315 and other common SWC flange coupling sizes.
Sealing Design: Equipped with double-lip oil seals to retain lubrication and prevent dust ingress.
Application Versatility: Suitable for metallurgy, mining, cement, paper, shipbuilding, and construction machinery.

FAQ – Hardened Cross Bearing Kit for SWC Flange Universal Coupling
Q: What materials are used in your cross bearing kit?
A: Our kits are made from case-hardening alloy steel (typically 20CrMnTi or 40Cr) with carburizing heat treatment to achieve HRC 58-62 surface hardness. The core remains tough for impact resistance.Q: Is this kit compatible with my existing SWC coupling?
A: Yes, we produce kits for standard SWC flange sizes from SWC-180 to SWC-620. Please provide your coupling model or flange dimensions to confirm fitment. Non-standard sizes are also customizable.Q: How do I install the cross bearing kit?
A: Installation is straightforward – remove the old cross assembly, clean the flange bores, lubricate the new bearing journals, and bolt the flange halves together. A detailed instruction sheet is included.Q: What is the typical lifespan compared to standard units?
A: The hardened surface significantly extends service life. Under normal operating conditions, our kit can last 1.5-2 times longer than unhardened variants, depending on load and lubrication.Q: Do you offer a warranty?
A: Yes, we provide a 12-month warranty against material or workmanship defects. Damage caused by improper installation or excessive overload is not covered.Q: What packaging do you use for export?
A: Each unit is individually wrapped in anti-rust paper, then packed in sturdy cartons or wooden cases (customizable) to prevent damage during shipping.Q: Can you supply other spare parts for SWC couplings?
A: Absolutely – we also offer flange yokes, bearing caps, oil seals, and complete couplings. Contact us for a comprehensive parts list.Q: What certificates do you have?
A: Our factory is ISO9001:2015 certified. Material certificates and test reports are available upon request.
