Clamp & Split Couplings
TransDrive Rigid Couplings are offered in both one-piece and two-piece clamp designs, with or without keyways, and are available in high-strength steel or corrosion-resistant stainless steel. These precision-engineered couplings provide a solid and secure connection between shafts where exact alignment is critical.
Unlike traditional set screw couplings, TransDrive’s clamp-style designs encircle the shaft evenly, delivering superior torsional holding power without causing shaft damage, fretting, or marring. The clamp mechanism ensures a tight, uniform grip that maintains alignment even under demanding operating conditions.
The two-piece clamp style offers added convenience, allowing for quick installation and removal without disturbing adjacent machine components – ideal for maintenance and system adjustments. Additionally, the use of opposing screws in the design promotes balance and minimises vibration at higher speeds.
TransDrive Rigid Couplings are the ideal choice for applications requiring maximum strength, alignment accuracy, and minimal shaft wear in precision systems such as servo drives, robotics and motion control assemblies.
