Features
・New coupling that incorporates tolerance endplay function like a universal joint. |
Configuration and materials
|
・Key groove shape complies with new JIS standards. |
Dimensions of key groove shape |
|
Assembly:Example Application |
・Fix the shaft-coupling component using a strong adhesive, such as "Loctite". ・Strong high-viscosity grease is applied to the ball joint. ・Since the inner hub is free in the axial direction during rotation, it has left-right movement. |
