3/4" G100 Precision Carbon Steel Bearing Balls

Introduction

PGN Bearings 3/4" G100 carbon steel bearing balls provide a practical combination of substantial size, consistent geometry, and smooth mechanical contact. With a nominal diameter of 19.05 mm, they are suitable for internal supports, positioning devices, retention mechanisms, and industrial assemblies designed for this specific ball size.

Manufactured from carbon steel, these precision balls offer dependable mechanical strength and good wear resistance for compatible applications in controlled, non-corrosive environments. Their G100 grade provides more refined dimensional consistency than broader grades such as G500, making them appropriate for mechanisms where repeatable contact and uniform movement are important.

Each ball has a listed unit weight of 1.002 oz, equivalent to approximately 28.4152 g. Before installation, verify the required diameter, material, precision grade, weight, operating environment, and surface condition specified for the equipment.

Hero Product Snippet

A 3/4" (19.05 mm) G100 precision carbon steel ball with a smooth surface finish for internal supports, positioning systems, retention devices, and compatible industrial mechanisms.

Recommended Applications

• Internal support mechanisms
• Mechanical positioning systems
• Retention and locking devices
• Compatible valves and flow-control mechanisms
• Industrial guides and movement systems
• Transfer and support assemblies
• Mechanical fixtures and custom equipment
• Maintenance of assemblies specified for 3/4" G100 carbon steel balls

19.05 mm Diameter for Mechanical Integration

The 3/4" diameter provides a useful balance between contact area and installation space. At 19.05 mm, the ball is large enough for substantial mechanical interfaces while remaining compact enough for a broad range of internal mechanisms and custom assemblies.

Compatibility depends on the dimensions of the track, seat, housing, or retention device. The nominal diameter should always be compared with the original equipment specification before installation.

G100 Precision for Repeatable Contact

G100 identifies the precision grade of the ball. In general, this grade provides more refined geometric control than higher numerical grades such as G500, supporting consistent contact in properly designed mechanisms.

Precision grade alone does not determine suitability. Clearances, alignment, lubrication, movement speed, and adjacent component geometry must also be evaluated.

Carbon Steel Construction

Carbon steel offers a practical combination of mechanical strength and wear resistance for general industrial applications. It is commonly used in internal supports, mechanical devices, and assemblies operating under compatible conditions.

Because no chemical composition, hardness value, or load rating is provided on the product page, these properties should not be assumed. Application-specific performance must be validated according to the equipment requirements.

Smooth Surface Finish

PGN describes its carbon steel balls as having a smooth surface without flats, pits, soft spots, or cuts. A uniform finish can contribute to regular contact with compatible seats, tracks, guides, and support surfaces.

Protect the finish during transportation, handling, and installation. Impacts, abrasive particles, or contact with damaged components may mark the surface and affect movement-sensitive applications.

Unit Weight and Motion Response

The listed unit weight is 1.002 oz, equivalent to approximately 28.4152 g. This mass may influence acceleration, return movement, positioning response, and interaction with springs or retaining components.

When weight is functionally important, verify the actual unit before installation. The ball should not be treated as a calibrated mass or measurement standard unless supported by separate certification.

Storage and Corrosion Protection

Carbon steel is not stainless and may oxidize when exposed to moisture, condensation, fingerprints, or corrosive substances. Store the balls in a clean, dry environment and avoid unnecessary direct handling.

When compatible with the application, a suitable temporary protective film may help preserve the surface during storage. Remove any residue as required before placing the ball into service.

FAQ

What is the diameter of these carbon steel balls?

The nominal diameter is 3/4", equivalent to 19.05 mm.

What does G100 precision mean?

G100 is the listed precision grade. It provides a reference for geometric and dimensional consistency and is more refined than broader grades such as G500.

How much does each ball weigh?

The listed unit weight is 1.002 oz, equivalent to approximately 28.4152 g.

Can these balls be used in any 3/4" mechanism?

Not automatically. The diameter, precision grade, material, weight, clearances, and operating conditions must match the equipment requirements.

Are carbon steel balls corrosion resistant?

Carbon steel does not provide the corrosion resistance of stainless steel. Keep the balls dry and protected from moisture and corrosive substances.

Can these balls be used as grinding media?

This product is presented as a G100 precision bearing ball rather than dedicated grinding media. Use purpose-designed grinding media when the application involves continuous milling or impact processing.
