Spherical washers are essential for applications requiring precise alignment and load distribution, especially on uneven surfaces. Their unique design allows for slight angular misalignment, preventing stress concentration and ensuring the integrity of bolted joints. Choosing the correct type is crucial for optimal performance and longevity in demanding industrial settings.
Application: For bench grinders with 1/2" spindles
Includes: One set of spherical washers
The spherical washer consists of one male washer and one female washer. When nested, they can rotate slightly to compensate for tolerance variations and uneven surfaces. They're good for die and fixturing applications.
Application: Suitable for bench grinders with a 5/8-inch spindle
You can choose to install a 2 mm flat washer as needed
The spherical washer consists of an external threaded washer and an internal threaded washer. When nested, they can be slightly rotated to compensate for tolerance variations and uneven surfaces. They are suitable for mold and fixture applications.

How to Choose the Best Spherical Washers
Material Choice
Stainless Steel: Offers excellent corrosion resistance and strength, ideal for outdoor or wet environments.
Carbon Steel: Provides high tensile strength and is often used in heavy-duty applications where corrosion is less of a concern.
Brass/Bronze: Suitable for applications requiring non-sparking properties or good electrical conductivity.
Size and Load Capacity
Bolt Size Compatibility: Ensure the washer's inner diameter matches the bolt or stud size precisely.
Load Requirements: Consider the maximum weight or force the joint will bear. Higher load capacities are typically associated with thicker, stronger materials.
Angular Misalignment Tolerance: Spherical washers are designed to accommodate a certain degree of tilt. Assess the expected misalignment in your application to select a washer with adequate tolerance.
Frequently Asked Questions
What is the primary function of a spherical washer?
A spherical washer's main purpose is to compensate for angular misalignment between a bolt and a surface. It allows for slight tilting, which prevents stress from concentrating at the contact points and ensures a more even distribution of clamping force.
When should I use a spherical washer over a standard flat washer?
You should opt for a spherical washer when the mating surfaces are not perfectly parallel or when there's a risk of movement or vibration. Standard flat washers are suitable for perfectly aligned joints, but spherical washers are necessary for applications requiring flexibility.
How do I determine the correct size of a spherical washer?
The size is determined by the diameter of the bolt or stud it will be used with. The inner diameter of the spherical washer must closely match the nominal size of the fastener to ensure a snug fit and proper function.
Can spherical washers be used with different types of nuts?
Yes, spherical washers can be used with various types of nuts, provided the nut's shape allows for the necessary angular movement. They are often paired with mating spherical nuts or used with standard nuts on surfaces that require slight angular compensation.
