Flexible power transmission: this polyurethane coupling insert is designed for use in industrial couplings to transfer torque smoothly and reliably. It provides elasticity between driving and driven components to maintain steady operation across machinery drives, conveyor systems, and pumps. Durable, strength material: made from strength polyurethane elastomer, the insert offers bending strength and wear resistance for long service life under repeated loading. Oil resistant for realworld environments: the polyurethane compound shows low swelling with mineral oil and minimal degradation from fuel oil and mechanical oils, maintaining performance across typical industrial lubrication conditions. Continuous operation ready: the design includes a polyurethane plum blossom pad that sustains repeated engagement and continuous working cycles without rapid loss of function, making it suitable for demanding, round‑the‑clock applications. Problem solving benefits: Reduces downtime by delivering reliable, longlasting coupling performance. Absorbs shock and transmits torque smoothly to help protect bearings and gear trains. Maintains compatibility and performance in oily, lubricated environments. Key attributes at a glance: Function: flexible insert for power transmission in jaw/plum‑blossom style couplings Material: ‑strength polyurethane elastomer with plum blossom pad Performance: bending strength, wear resistance, continuous working capability Environment: oil resistant (low swelling with mineral oil; resistant to fuel and mechanical oils) Typical applications: 1. Machinery drives — replaces worn inserts in machine tool drives to restore smooth torque transfer and reduce vibrationrelated wear. 2. Conveyor systems — used in conveyor gearboxes and motor couplings to maintain reliable operation under continuous duty. 3. Pumps and compressors — absorbs torsional shocks and protects shafts and seals in fluid‑handling equipment. This coupling insert is a directfit, heavy‑duty replacement component for industrial coupling assemblies where flexibility, durability, oil resistance, and continuous operation are required.
