MCNB Electromagnetic Spring-Applied Brake
(Torque Range: 1.8-36 in-lbs / 0.2-4Nm)

Ogura's industrial electromagnetic clutches

Small spring applied brake available with either D hub, set screws or straight bore. Standard voltages are 24 and 45 but other voltage options are available. Units are designed to give 100% rated torque right out of the box. No burnishings required.

Ogura Design Advantages

100% RATED TORQUE

You can count on getting the rated torque for holding applications right out of the box.

LONGEVITY

Wear-resistant friction material and corrosion resistant surfaces provide extended operational life.

VOLTAGES AVAILABLE

The MCNB series brake is available in 24VDC, 45VDC or 90VDC. (The 45VDC type can be used with half-wave rectification of 100VAC).

HIGH RELIABILITY

Friction material has high coefficient of friction and superior wear resistance, offering high torque and long life.

TWO BORE TYPES OFFERED

In the new series a standard D cut metric bore is available. This is a plastic molder hub with an anti rattle feature.
In the older version a standard machine bore is available in both inch and metric dimensions with two set screws.
