UMAX logo bold.jpg THE ULTIMATE SERIES
UMAX series has the longest warranty in the industry by use of superior materials combined with innovative technologies owned by UMAX. Solid Steel Cores (weight heads) are coated with specially formulated cast polyurethane (CPU) for weathering high impact environments. Dura-Edge technology (patent pending) further increases the durability of the urethane protection. The weight heads are fastened to the handles made of heat-treated alloy steel (the strongest used in the industry) secured by patented Dual-Lock technology.

Dual-LockDual-Lock: ELIMINATES LOOSENING that occurs in a single bolting assembly or welding assembly system. This patented technology incorporates two sets of bolting threads that interlock when tightened. The Dual-Lock handle or bar becomes a bolt when it screws into the head of a dumbbell or barbell and then becomes a nut when another bolt is screwed into the handle or bar from the opposite direction. Each bolting thread blocks the other from rotating and loosening even in heavy impact environments. The Dual-Lock is Unsurpassed in Achieving Structural Stability.

Dual-Lock: ENABLES THE USE OF HIGH STRENGTH DUMBBELL HANDLES. The high strength is achieved by heat treating alloy steel. However, the heat created in weld processing will anneal (weaken) the material. Dual-Lock technology eliminates the need for welds in dumbbell assembly so The Strength of Our Dumbbell Handles is Never Compromised.

Dual-Lock: UMAX CUSTOMERS BENEFIT BY PAYING LESS FOR BETTER PRODUCTS. Without welds and internal "forced" fastening mechanisms, this technology allows our dumbbells and barbells to be assembled from finished modular components that are already fully urethane encased or hard chrome plated. This reduces production cost and material loss compared to other assembling methods.

Dual-EdgeDura-Edge: Allows extra urethane to be used on the front edge of dumbbells and barbells where they receive the most impact. More urethane at this critical point helps absorb the stress of impact that occurs in heavy use environments. Dura-Edge protects the structural stability of dumbbells and barbells and extends the life of the urethane coating.

DUMBBELL HANDLES
Material Yield Strength Used For
  1018 Low Carbon 33,000 psi  Some Low End Dumbbells
  1045 Medium Carbon 36,000 psi  Pro-Style Dumbbells and Welded Dumbbells
  304 or 316 Stainless Steel 30,000 psi  Some Expensive Dumbbells
  5140 Alloy Heat Treated 114,000 psi  UMAX Dual-Lock Dumbbells up to 70 lbs
  4140 Alloy Heat Treated 135,000 psi  UMAX Dual-Lock Dumbbells 75~150 lbs

Our heat-treated alloy steel has superior yield strength and negates the need for overly thick handles and is too hard to embed coarser knurling (like good commercial 7' bars).
