Spline Shafts & Couplings

Spline shafts and couplings work in harmony to create more machine torque. The inner diameter of the shaft coupling perfectly matches the outer protrusions of the spline shaft itself, producing a tighter fit, which produces more torque with less resistance. A spline coupling comes in three major types: involute spline, straight spline, and precision splined hubs. Zoro also carries rigid clamp couplings, shaft couplings, shaft collars, and shaft sleeves.
