Dual-Sealed Bearing enhances 1.9 in. axle-free conveyor rollers.
Press Release Summary:
May 21, 2012 - GenStarÂ® ELIMINATOR 4007 w/IronGrip Adapter contains one ABEC-1 core precision bearing, with roller capacity of 270 lb, capable of spanning roller lengths through 40 in. Carbon steel adapter allows secure crimp fit roller assembly along with maximized concentricity, which also minimizes deflection and provides flexibility for various crimping pressures at tube while isolating ABEC-1 precision core bearing during crimping process.

FRANTZ Manufacturing Company Launches GenStar® ELIMINATOR 4007 Bearing for 1.9" Axle-Free Conveyor Rollers
Press release date: May 14, 2012
Axle-free conveyor rollers. The ability of axle-free rollers to perform at longer lengths has long vexed conveyor bearing manufacturers. Plastic-housed precision bearings can loosen and walk out of the tubes at all but the lightest loads. With thru axles, minor deflection distorts and damages precision bearings. Deflected axles can bump up against the inside of the roller tube at these lengths causing roller manufacturers to add "center pucks" adding cost and more weight. The elimination of a thru axle at longer lengths, allows for the tube to deflect without the same axle deflection on the ball races, permitting use of lighter gauged 1.9" rollers as a substitute for heavier and more costly 2.5" rollers in many pallet type conveyors.
IronGrip Adapters. FRANTZ has long championed its IronGrip Adapters by offering a broad line that cost effectively adapts smaller diameter bearings to larger diameter tubes. These adapter designs were incorporated into the FRANTZ popular GEN II® line of semi precision bearings and its workhorse GenStar® line of ABEC-1 precision bearings. The carbon steel adapter allows for a very secure crimp fit roller assembly along with improved concentricity vs. plastic alternatives. The IronGrip adapter is designed to provide flexibility for various crimping pressures at the tube while isolating the ABEC-1 precision core bearing during the crimping process. FRANTZ engineers used this IronGrip Adapter design as the foundation for the new GenStar® ELIMINATOR. The IronGrip Adapter allows for the use of a single ABEC-1 precision core bearing. The tube and mated bearing assembly carry the weight of products with reduced total roller deflection. Thus, it eliminates axle deflection as the determining factor in total roller load carrying capacity.
FRANTZ unique design. FRANTZ GenStar® ELIMINATOR w/IronGrip Adapter contains a single ABEC-1 core precision bearing with a roller capacity of 270 lbs capable of spanning roller lengths through 40" with strong continued performance through 72". FRANTZ engineers have tested the assembly performance to exacting CEMA standards with exceptional results. Inside the bore is a direct injection molded bushing made of nylon static discharge material. Both the steel adapter and the nylon direct injected bushing provide for excellent concentricity and extended bearing life. The dual sealed core ABEC-1 precision bearing is packed with Chevron SRI® grease providing a wide operating temperature range of -20° F to 350°F. The carbon steel stub shaft is spring loaded within the assembly with the spring being retained by an ultra sonic welded cap instead of commonly used clips. Roller installation is made easy by the shaft at each end being independently spring loaded.
Green Solution. The ELIMINATOR reduces costs, weight, material, energy requirements, noise and waste stream to benefit FRANTZ customers and the environment. The hex axles are eliminated reducing steel usage and inbound freight. Rollers are 28% lighter resulting in lower fuel usage during outbound delivery. ABEC-1 precision core bearings operate quietly, reducing noise. The ELIMINATOR has up to one half the co-efficient of friction of dual bearing competitor assemblies. Starting torque is reduced and is equivalent to FRANTZ workhorse GenStar® 4003's allowing for smaller drive motors saving energy. The end of life for the rollers and conveyors produces a smaller waste stream. Finally, labor cost saving is a major benefit. Up to 50% improved productivity can be demonstrated in the manufacture and assembly of rollers.
GenStar® ELIMINATOR w/IronGrip Adapter is made in Sterling, Illinois, USA.
