SURE FLEX Rubber Gears, Gear Couplings, Rubber Tooth Couplings – 6H/7H/8H/9H/10H/11H/12H Series
Product Description
SURE FLEX rubber gears, gear couplings, and rubber tooth couplings (focusing on 6H, 7H, 8H, 9H, 10H, 11H, 12H series) are high-performance industrial power transmission components, integrating the wear resistance of gears with the flexibility of rubber elastomers. Specifically engineered for heavy-duty torque transfer and misalignment compensation, these couplings are designed to deliver reliable, low-maintenance operation across a wide range of industrial applications, with the 6H-12H series covering medium to large size requirements for diverse working conditions.
All 6H-12H series products feature premium Hytrel elastomeric tooth sleeves (a key characteristic of H-series couplings), which offer four times the torque capacity of standard EPDM or Neoprene sleeves, making them ideal for high-torque industrial scenarios. The rubber gears and rubber tooth structures are precision-machined to ensure tight meshing with gear couplings, providing excellent vibration damping and torsional shock absorption—Hytrel sleeves wind up approximately 7° torsionally at their rated torque, effectively reducing wear on connected equipment such as motors, pumps, and gearboxes. The gear couplings adopt a sturdy design, with flanges available in cast iron (S-type) for sizes 6H-12H, supporting pilot bored or finish bored customization to match specific shaft requirements.
A standout advantage of SURE FLEX 6H-12H rubber tooth couplings and gear couplings is their maintenance-free design—no lubrication, gaskets, or covers are required, ensuring clean, quiet performance and reducing operational costs over the long term. Equipped with unique 4-way flexing action, they effectively absorb angular, parallel, and axial misalignment: sizes 6H-7H feature 1.5° curved-face crowned teeth for enhanced misalignment capability (up to ±1.5° static angular misalignment), while sizes 8H-12H adopt straight-faced involute stub teeth that distribute contact pressures evenly, minimizing tooth wear and extending service life. This flexibility also simplifies installation, as alignment can be completed with just a straightedge and feeler gage, no specialized tools needed.
Covering full sizes from 6H to 12H, each model is tailored to specific torque and size demands: 6H offers a rated torque of 1,800 in-lbs and max RPM of 6,000, 7H delivers 2,875 in-lbs torque at 5,250 RPM, 8H reaches 4,530 in-lbs at 4,500 RPM, 9H provides 7,200 in-lbs at 3,750 RPM, 10H offers 11,350 in-lbs at 3,600 RPM, 11H delivers 18,000 in-lbs at 3,600 RPM, and 12H (the largest in this range) is engineered for even higher torque capacities to meet heavy-duty industrial needs. These products are widely used in manufacturing, mining, oil & gas, paper making, and food processing industries,适配 pumps, compressors, conveyors, agitators, and rolling mills. They are directly interchangeable with standard SURE FLEX components, facilitating quick replacement and minimizing equipment downtime, making them a cost-effective solution for global industrial customers.
