(25 Pieces) PGN 1-1/16 in Pinball Replacement Steel Balls - Durable 27

In this review the reviewer looks at a 25-piece set of PGN G100 steel balls intended as pinball replacements and industrial spheres. The bottom line is that these 27 mm balls are best for hobbyists and workshop users who need a consistent, ISO 9001:2011 made steel sphere at a low replacement cost; the single biggest reason to buy is their higher quality and durability compared with generic balls, which can reduce replacement and maintenance cycles for machines and projects.

Key Features

• G100 steel grade: provides consistent hardness and finish for dependable rolling and contact performance in flippers, ramps, and mechanical fixtures.
• ISO 9001:2011 assurance: indicates a quality management process behind production, which helps ensure dimensional consistency across the 25-piece set.
• Exact diameter: 1-1/16 in (27 mm) size gives clear interchangeability for machines and assemblies that specify that diameter.
• Consistent weight: at about 2.849 ounces (80.789 grams) each, the balls offer repeatable inertia and feel in play or mechanical applications.
• Durability focus: the G100 material and manufacturing aim to reduce the frequency of replacements and lower maintenance costs over time.

Who It's For

The 25-piece PGN set is ideal for pinball hobbyists, arcade technicians, and small shops that need multiple replacement balls or spares for machines and fixtures. Because they come in a pack, they also suit projects and prototypes where several identical precision spheres are needed.

Those who should look elsewhere include users seeking mirror-polished collector ball appearance or stainless corrosion resistance if aesthetics and long-term outdoor exposure are primary concerns. Also double-check the 1-1/16 in size against your machine, since some customers found the diameter did not match their expectations.

Pros & Cons

Pros

• Consistent G100 steel construction gives a solid, durable feel and predictable performance.
• ISO 9001:2011 production suggests uniform sizing and quality control across the 25 pieces.
• Good value for money when replacing multiple balls or stocking spares for maintenance.
• Weight and size are specified clearly, making selection straightforward for compatible applications.

Cons

• Finish may appear dark or matte and some users have concerns about surface appearance and potential corrosion if not protected.
• Size will be too large for setups that require smaller pinballs, so compatibility must be verified before purchase.

Specifications

Our Verdict

The PGN 25-piece G100 steel ball set is a practical buy for hobbyists and technicians who need multiple consistent 27 mm spheres that prioritize durability and predictable performance. It offers good value for maintenance and replacement needs, though buyers should confirm size compatibility and plan for surface protection if corrosion resistance or a polished look is required.

Frequently Asked Questions

Are these the exact 27 mm size?
Yes, each ball is listed as 1-1/16 in (1.0625 in) which corresponds to 27 mm, so verify this matches your machine requirements.

Do they resist rust and corrosion?
The listing emphasizes G100 steel and durability but some customers noted a dark, matte finish and expressed concern about appearance and potential corrosion, so consider applying protection or using them in dry environments.

Are these suitable for pinball play?
They are marketed as pinball replacement spheres and many customers found them functional, but feedback is mixed on play quality and fit so test one ball before replacing all machine balls.
