S-91131A122 Male and Female Leveling Washers

Key Features & Benefits at a Glance

• Superior angular misalignment compensation with 3° maximum correction angle for perfect alignment in uneven surfaces and bolted joints
• Exceptional load distribution capability through spherical design that prevents stress concentration and component failure
• Enhanced corrosion resistance thanks to black-oxide steel finish that protects against rust in demanding industrial environments
• Consistent mechanical performance ensured by Rockwell C25 hardness rating for reliable strength and durability
• Precision dimensional compatibility with 1 1/8" screw systems and replacement male washers for seamless integration
• Regulatory compliance assurance meeting both RoHS 3 and REACH standards for safe, environmentally responsible usage
• Optimized thickness tolerance (0.485"-0.515") ensuring uniform pressure distribution and secure fastening

Professional Applications & Engineering Value

This heavy-duty spherical washer addresses critical engineering challenges in industrial applications where surface irregularities and angular misalignment compromise joint integrity. The black-oxide steel construction provides essential corrosion protection while maintaining the Rockwell C25 hardness necessary for sustained performance under heavy loads. The precisely engineered spherical interface enables up to 3° angular correction, distributing stress evenly across mating surfaces to prevent premature fatigue failure. Particularly valuable in structural applications, machinery assembly, and heavy equipment maintenance, this 1 1/8" spherical washer ensures reliable performance where standard flat washers would fail due to misalignment issues, making it indispensable for engineers specifying components for demanding environments.

Specification Summary & Compliance

Manufactured to precise dimensional standards with female ID of 1.25", female OD of 2.250", male ID of 1.188", male OD of 2.25", and consistent thickness between 0.485"-0.515". The washer conforms to inch system measurement requirements and delivers reliable performance with 3° maximum correction angle capability. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures suitability for global industrial applications while maintaining the highest standards of material safety and environmental responsibility.
