A commercial-grade cast iron kettlebell line that runs from 10 to 100 lb, from a supplier that has equipped gyms since 1986.
Power Systems has supplied commercial gyms, schools, and studios out of Knoxville, Tennessee since 1986, and the Kettlebell Prime is the current version of its core cast iron bell. Each bell is a single casting with a matte black powder coat that holds chalk, a colored band on the handle for weight identification, and the weight tooled into both sides. The line runs 15 sizes from 10 lb at $43.00 to 100 lb at $286.50, which is a wider top end than most home-focused brands carry.
The design follows the classic gym pattern: handle diameter and bell size grow with the weight rather than staying fixed the way competition-style bells do. That makes heavy bells comfortable for two-hand swings and carries, but it also means your grip and rack position change slightly as you move up the ladder. If you are training for kettlebell sport, a competition bell with uniform dimensions is the better tool.
The honest math on any fixed-weight bell line applies here. Bells are sold individually, so building a 10 to 50 lb ladder means five purchases and roughly $265 to $365 depending on the steps you choose, plus shipping on cast iron. An adjustable kettlebell costs less per pound of range and stores in one footprint. What you get in exchange is a bell with no moving parts, no plates to shift mid-swing, and nothing to fail.
Prices at this weight range are competitive: about $1.44 to $4.30 per pound across the line, with the heavier bells cheaper per pound. All 15 sizes were in stock at the time of this review, and racks are available separately if the collection grows.
Home lifters who want fixed cast iron bells with a chalk-friendly powder coat and a path to genuinely heavy weights.
You want one adjustable bell to save money and floor space, or you train kettlebell sport and need competition dimensions.

Power Systems Kettlebell Prime - buyer FAQ
What weights does the Power Systems Kettlebell Prime come in?
Fifteen weights, from 10 lbs up to 100 lbs. The range steps in 5 lb increments from 10 through 60 lbs, then in 10 lb increments at 70, 80, 90 and 100 lbs. Each bell is sold as a single unit rather than as a set, and Power Systems sells storage racks separately.
What is the warranty on the Power Systems Kettlebell Prime?
Power Systems' published warranty schedule covers Kettlebell Prime, SKUs 22802 through 22818, for 24 months, with 6 months on the surface finish. Returns are accepted within 30 days of receipt with a return authorization obtained in advance. The company's stated baseline is 90 days free of manufacturer defects from the invoice date.
Are Power Systems Kettlebell Prime bells coated or bare cast iron?
They are solid cast iron finished in a matte black powder coat. Power Systems describes the surface as smooth and slightly textured, so it holds chalk and stays comfortable in the hand. This is a painted finish rather than vinyl or rubber, which is why the surface portion of the warranty is the shorter 6 month term.
How do you tell the weights apart on Power Systems kettlebells?
Each bell carries a colored band on the handle plus a tooled weight marking on each side, so the number stays readable from either direction on a rack. Power Systems also notes that handle size and overall bell size increase with weight across the 10 lb to 100 lb range, so heavier bells feel physically larger.
Will the Power Systems Kettlebell Prime fit a standard kettlebell rack?
Power Systems does not publish handle diameter or per-weight bell dimensions, so rack fit cannot be confirmed from the spec sheet. The company states only that handle and bell size increase with weight across the 15 sizes, and sells its own kettlebell racks separately. The 10 lb bell ships in an 8 x 5.5 x 5.5 inch box.
