Open Spelter Sockets JIS With Bolt
Focuses on the OSS series manufactured according to JIS standards. Supporting MBLs from 31 to 104 UStons, this document specifies the dimensional differences required for JIS compliance and provides a full matrix of technical parameters for the quenched and tempered cast steel bodies.
Engineered for Global Compatibility: High-Performance JIS Open Spelter Sockets with Bolt
The JIS Open Spelter Socket with Bolt is a high-capacity termination solution specifically designed to meet Japanese Industrial Standards (JIS) while providing the structural resilience required for global lifting operations. Manufactured from quenched and tempered cast steel, these sockets feature a secure bolt fastening system to provide permanent wire rope terminations with superior load transfer and fatigue resistance in demanding industrial environments.
Maximum Strength & Material Integrity
- Quenched & Tempered Casting: The socket body is manufactured from high-grade cast steel, quenched and tempered for maximum durability.
- Standardized Load Capacities: Standard models offer a Minimum Breaking Load (MBL) ranging from 31 UStons to 104 UStons.
- Certified Quality Assurance: Every unit is provided with an EN 10204-2.1 declaration of conformity and an EN 10204-3.1 material certificate.
- Durable Corrosion Protection: Features a standard finish of blue primer coating and hot-dipped galvanizing for long-term field performance.
Industrial Precision & JIS Compatibility
- JIS Specific Design: Precision-engineered to align with JIS requirements for specialized rigging hardware and block integration.
- Secure Fastening: Utilizes a robust bolt assembly to ensure the connection remains locked in place, preventing unintended release.
- Controlled Manufacturing: Maintains strict dimensional tolerances of ±5% for the jaw opening (W) and pin diameter (øP).
- Broad Wire Compatibility: Optimized to accommodate wire rope diameters ranging from 3/4″ up to 1-1/2″.
JIS Open Spelter Socket (with Bolt) Technical Specifications
Below is the technical specification range for JIS models. Please contact our technical team for full dimensional data (A, B, C, D, øH, øP, T, TB) and MBL verification based on your specific wire rope requirements.
⚠ Safety Warning: Always adhere to the Minimum Breaking Load (MBL) and ensure that all wire rope terminations are conducted by qualified personnel. Be aware that surface finishes like hot-dip galvanizing or paint may slightly increase overall thickness and jaw dimensions; always verify fit-up on site. Refer to the comprehensive safety documentation on pages 136-198 for full maintenance and speltering procedures.
