Product Description
[Header: High-Temperature & Oil-Resistant Damping: Hytrel GS Series Jaw Coupling Spider Insert]
The Apexcoupling Hytrel GS Series Flexible Jaw Coupling Spider Insert is an engineered elastomeric cushion designed for curved jaw couplings operating under severe mechanical stress, oil exposure, and extreme thermal conditions. Manufactured from imported Hytrel thermoplastic elastomer (and available in premium PU/Polyurethane variants), this flexible insert dampens torsional vibration, absorbs operational shock loads, and compensates for angular, parallel, and axial shaft misalignments.
Fully interchangeable with international curved jaw coupling standards—including ROTEX 14 through ROTEX 180 profiles—the GS series ranges from compact GS-7 up to GS-90 sizes. Engineered to withstand continuous operating temperatures up to 200°C, these hard, wear-resistant inserts deliver exceptional chemical resistance to hydraulic oils, lubricants, grease, and fuels, ensuring low maintenance overhead and extended service life for industrial pump sets, compressors, and motor drives.
[Core Product Advantages / Unique Selling Points]
Elevated Thermal Resistance (Up to 200°C): Formulated with imported Hytrel thermoplastic elastomer to maintain mechanical elasticity and torque capacity under elevated temperature conditions (up to 200°C).
Superior Oil & Chemical Inertness: Highly resistant to hydraulic fluids, industrial lubricants, solvents, and fuels, making it ideal for harsh pump, compressor, and hydraulic system environments.
Rotex Interchangeable Curved Jaw Profile: Standardized dimensions perfectly match ROTEX series curved jaw couplings from size ROTEX 14 to ROTEX 180 (GS-7 through GS-90).
Hard & Wear-Resistant Elastomer Structure: Designed with exceptional abrasion resistance and high shore hardness to prevent premature tooth shear under heavy reverse-torque cycles.
Torsional Vibration Damping: Absorbs peak shock loads and dampens motor-generated harmonic vibrations, protecting connected bearings, gears, and drive shafts.
Full Model & Material Compatibility: Available across GS, GR, MT, T, NM, FCL, HRC, and L/J model families in PU, Hytrel, rubber, metal, and stainless steel assemblies.
Global Standard Certifications: Manufactured in compliance with RoHS, ISO 9001, and Bureau Veritas (BV) quality management systems.
Direct Factory Custom Sourcing: Full support for non-standard hardness ratings, custom elastomer formulations, and OEM/ODM/OBM manufacturing.
