Set Screw Jaw Coupling – JSSA Series

Features

• High torque, small size, zero revolution clearance.
• Colloid uses German TPU, Manufactured by special processes, The 24 hour compression variant is only 15%, which is better than 35% of ordinary materials.
• 95A moderate colloid hardness, Solve the problem of softness impact accuracy and insufficient hard buffer.
• High and low temperature resistance, Temperature range:-30~100℃.
• Intermediate elastomer absorbs vibration,compensates for radial, angular and axial deviations.
