3-1/2" G100 AISI 52100 Chrome Steel Bearing Ball – 1 Piece
Introduction
The PGN Bearings 3-1/2" G100 chrome steel ball is designed for projects requiring a solid, large-diameter spherical component with a smooth surface finish and good wear resistance. Measuring 3-1/2 inches, or 88.9 mm, this ball stands apart from conventional sizes through its substantial dimensions, mass, and suitability for larger mechanical assemblies.
Manufactured from AISI 52100 chrome steel, a material widely used for mechanical components exposed to contact and friction, the ball provides the high hardness associated with this alloy and dependable performance in compatible applications. Its G100 precision grade supports consistent geometry and a smooth surface for industrial fixtures, rugged mechanisms, special-purpose designs, and equipment development.
Supplied as one piece, this 88.9 mm chrome steel ball is convenient for projects that require a single large component rather than a bulk package. Before installation, verify dimensional, precision, weight, environmental, and retention requirements, particularly because chrome steel does not provide the same corrosion resistance as stainless steel.
Hero Product Snippet
Solid 3-1/2" (88.9 mm) AISI 52100 chrome steel ball with G100 precision and a smooth surface finish, supplied as one piece for large-scale industrial and mechanical projects.
Recommended Applications
- Large mechanical devices
- Industrial assemblies requiring a solid 88.9 mm ball
- Compatible positioning, retention, or movement mechanisms
- Engineering projects and industrial prototypes
- Custom fixtures, supports, and special-purpose equipment
- Mass or counterweight elements after design validation
- Technical demonstration and training equipment
- Replacement in assemblies specified for a 3-1/2" G100 ball
Large Diameter for Special-Purpose Projects
The 3-1/2" nominal diameter makes this ball suitable for equipment and devices that cannot use conventional small- or medium-diameter industrial balls. Its 88.9 mm size must be considered when designing housings, tracks, supports, and retention mechanisms.
Because this is a solid and relatively heavy component, assembly compatibility should be evaluated before installation. Available space, mounting method, containment, and safe handling are important considerations for every application.
AISI 52100 Chrome Steel Construction
AISI 52100 is a chrome steel recognized for its high hardness and good wear resistance. These properties make it suitable for mechanical components exposed to repeated contact when operating conditions are compatible with the material.
Chrome steel should not be confused with stainless steel. For humid, corrosive, or chemically exposed environments, consider a different material or an appropriate surface-protection procedure.
G100 Precision and Consistent Geometry
G100 identifies the precision grade of the ball. This classification helps designers compare the product with the dimensional and geometric requirements of their equipment without assuming interchangeability with balls manufactured to another grade.
For critical applications, verify the required grade against the equipment drawing or manufacturer’s specifications. Using a G100 ball in a system originally designed for another precision class should be subject to engineering validation.
Smooth Surface for Uniform Contact
The ball has a smooth surface finish without visible defects such as flat areas, pits, or cuts. This supports more uniform contact in properly sized mechanisms, supports, and industrial fixtures.
Protect the finish during transportation, storage, and assembly. Drops, impacts against hard surfaces, or contact with abrasive materials may create marks that affect appearance or performance in surface-sensitive applications.
Single-Piece Package and Substantial Mass
SKU SB-3-1/2-CHROME-G100/1 corresponds to the one-piece package. The product page lists a nominal weight of 99.2 oz, equivalent to approximately 2.81 kg, which should be considered during handling and assembly design.
The single-piece package is convenient for individual replacements, prototypes, and custom projects. Confirm the actual unit weight before using the ball as a reference mass, balancing element, or counterweight.
Storage and Corrosion Protection
To help preserve the surface, keep the ball clean, dry, and protected from moisture. Storage in closed packaging away from corrosive agents can help reduce the possibility of oxidation during periods of inactivity.
When compatible with the application, a suitable protective film may be applied. Before installation, remove residues using a procedure that will not damage the finish or contaminate the equipment.

FAQ
What is the diameter of this chrome steel ball?
The nominal diameter is 3-1/2 inches, equivalent to 88.9 mm.
How many balls are included?
SKU SB-3-1/2-CHROME-G100/1 includes one ball.
How much does the ball weigh?
The product page lists a nominal weight of 99.2 oz, equivalent to approximately 2.81 kg. Confirm the actual unit weight for applications that depend on an exact mass.
What does G100 precision mean?
G100 is the precision class listed for this product. Compare it with the dimensional and geometric requirements of the equipment before selection or replacement.
Can this ball be used in any bearing?
No. A 3-1/2" ball is unusually large for conventional bearings. It should only be used in assemblies specifically designed for its diameter, material, and precision grade.
Is AISI 52100 chrome steel corrosion resistant?
AISI 52100 provides good wear resistance but does not offer the same corrosion resistance as stainless steel. Keep the ball dry and protected from moisture and corrosive substances.
