Sure Flex Gear Couplings – Rubber Tooth Sleeve HS JE S Series 5/6/7/8/9/10/11/12
Product Description
Sure Flex gear couplings with rubber tooth sleeves, covering HS, JE models and S-type flanges in sizes 5, 6, 7, 8, 9, 10, 11, 12, are high-performance industrial power transmission components designed for reliable torque transfer and misalignment compensation. Engineered with precision gear structures and high-quality rubber tooth sleeves, these couplings integrate the durability of gear couplings with the flexibility of elastomeric components, making them ideal for a wide range of industrial applications that require stable, low-noise operation and minimal maintenance.
The rubber tooth sleeves are available in two main types to meet diverse working demands: JE series sleeves, made of EPDM or Neoprene rubber, feature one-piece solid or split construction for easy installation and excellent vibration damping performance; HS series sleeves, crafted from Hytrel or urethane, offer four times the torque capacity of standard EPDM/Neoprene sleeves, suitable for high-torque industrial scenarios. The S-type flanges, made of cast iron, are compatible with sizes 5 to 12, providing sturdy connection and reliable power transmission, while supporting pilot bored or finish bored customization according to specific shaft requirements.
With unique 4-way flexing action, these Sure Flex gear couplings effectively absorb angular, parallel, and axial misalignment, as well as torsional shock and vibration, reducing wear on connected equipment such as motors, pumps, and gearboxes. A key advantage is their maintenance-free design—no lubrication or gaskets are required, ensuring clean, quiet performance and reducing operational costs over the long term. The precision-machined flanges allow for easy alignment using simple tools like a straightedge and feeler gage, eliminating the need for specialized equipment during installation and removal.
Covering full sizes from 5 to 12, our Sure Flex gear couplings with HS/JE rubber tooth sleeves and S-type flanges are widely used in industries such as manufacturing, mining, oil & gas, paper making, and food processing,适配 pumps, compressors, conveyors, agitators, and rolling mills. They are designed for direct interchangeability with standard Sure Flex components, facilitating quick replacement and minimizing equipment downtime. Whether for standard or high-torque applications, these couplings deliver consistent performance, durability, and cost-effectiveness for global industrial customers.
