Our polyurethane and rubber couplings are precision-engineered
through injection molding using high-quality TPU material or
CSM/SBR compounds. Designed specifically for metal shaft couplings,
they deliver outstanding performance characteristics including high
tensile strength, superior wear resistance, excellent elastic
resilience, and resistance to water, oil, and fatigue. We maintain
comprehensive mold sets to produce a full range of coupling types
including GR, GS, MT, ML, MH, Hb, HRC, L, T, NM, and Gear J series.
