The S90BF9-22A06 is a power-on flange-mounted brake with a 0.375 inch bore and a 0.125 inch keyway, designed for zero drag when de-energized and anti-backlash when energized. It mounts on a 2.33 inch square plate and weighs 0.9 pounds. The brake engages in 12 milliseconds and disengages in 32 milliseconds, with a maximum torque of 40 lbf-in and a coil resistance of 75 ohms at 24V DC. The initial working air gap at installation is specified as 0.006 to 0.013 inches.
Clutches and brakes are essential for the efficient control and transfer of drive torque, speed, and power in many rotational drive systems. Precision brakes and clutches can be used to cease or regulate movement.
A brake is utilized to decrease or halt a load (braking) in a motor (either forward or reverse). The function of a clutch is to disengage a drive shaft, pausing the rotation and transferring torque to an output shaft.
A clutch-brake is a single unit with the two combined functions of clutching and braking.
Brakes and clutches are classified by the method used to disengage or stop rotary motion (i.e., friction, mechanical, or electromagnetic), as well as the operative mechanism used to employ the chosen element (i.e., electrical, mechanical, pneumatic, or hydraulic).
We offer several types of brakes, including permanent magnetic brakes, power-off, power-on, and magnetic particle brakes. We also offer several clutch styles, including roller clutches, slip clutches, and electromagnetic clutch couplings.
