S-91944A040 Male and Female Leveling Washers

Key Features & Benefits at a Glance

• Superior misalignment compensation with a 3° maximum correction angle ensures optimal load distribution and prevents premature fastener failure in uneven mounting surfaces.
• Exceptional corrosion resistance from 18-8 Stainless Steel construction guarantees long-term reliability and performance in harsh or outdoor industrial environments.
• Enhanced mechanical strength with a Rockwell B80 hardness rating provides excellent durability and resistance to deformation under heavy loads.
• Precision dimensional fit with a 1.687" male ID and compatibility with 1 5/8" screw sizes ensures secure, vibration-resistant connections in demanding assemblies.
• Robust regulatory compliance with RoHS 3 and REACH standards makes this washer suitable for global supply chains and environmentally conscious manufacturing.
• Heavy-duty design featuring substantial thickness (0.673"-0.703") and large diameters supports high-stress applications requiring reliable spherical seating.
• Seamless system integration as part of a spherical washer set, allowing for easy pairing with replacement male washers for complete misalignment correction solutions.

Professional Applications & Engineering Value

This spherical washer is engineered to solve critical alignment issues in heavy machinery, structural steelwork, and precision equipment assemblies. The 18-8 Stainless Steel material provides inherent resistance to rust and chemical exposure, making it ideal for marine, chemical processing, and outdoor applications. Its 3° correction angle accommodates angular deviations between mating surfaces, reducing stress concentrations on bolts and preventing joint failure. The Rockwell B80 hardness ensures the washer maintains its shape under sustained pressure, while the inch-system dimensions offer compatibility with standard North American industrial components. By integrating this washer, engineers can enhance the longevity and safety of bolted connections in construction, transportation, and heavy equipment sectors, where misalignment is a common challenge.

Specification Summary & Compliance

This spherical washer conforms to inch system measurements with precise IDs (Male: 1.687", Female: 1.75") and ODs (Male: 3.25", Female: 3.250") for accurate fit. It is manufactured from 18-8 Stainless Steel with a specified hardness of Rockwell B80 and is designed for use with 1 5/8" screw sizes. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use worldwide.
