Overview
CB clutch is an ideal match for clutch as well as brake applications in operations that are high speed and cyclical. They are also suitable for coupling and general transmission of power.The sidewalls of an adaptable neoprene and cord actuating tube are used for delivering torsional resilience through power transmission. This enables the units to accommodate minor shaft alignment issues.
Torque up to 1,160,000 lb.in / 131,000 N.m
Reputed International manufacturer is EATON.
Reputed Chinese manufacturer as follow,DALIN,HANDONG,Rubflex
Application
Oilfield machinery
Printing machinery
Rubber-processing machinery
Tire-building machinery
Metal-forming machinery
Punch uncoiler machinery
Mold press machinery
Boat/Marine
Features:
1.Small appearance, but can transmit a lot of rotating force.
2. It has strong durability and wear resistance.
3. Long product life, safe and convenient operation.
4. The clutch can be easily installed or uninstalled when transmitting power.
How to Work
Typically, an engine comes with an output shaft, and this is located near the flywheel. The clutch is a type of device that comes in a system of grabbing disks or plates, which engage power from the machinery’s flywheel and transfer this power to the transmission.
