It has a balanced design for better performance in high RPM applications.6250", Steel, OD 1 5/16" Tightly controlled face to bore perpendicularity is maintained (TIR of This two-piece shaft collar has a 0.6250" bore, 1 5/16" OD, and 0.437" width.
This clamp type bellows coupling consists of two anodized aluminum hubs and a stainless steel bellows creating a lightweight low inertia coupling. Ruland standard length bellows couplings are a high torque zero-backlash coupling commonly found in responsive systems on semiconductor, solar, test and measurement, and printing equipment.500"x12mm,OD 1.625",L 2.
