    Products   Precision Brakes and Clutches for the Design Engineer



SDP/SI offers a selection of high-quality brakes and clutches as standard catalog items. Products include: spring wrapped clutches and brakes, mechanical slip clutches, reverse-acting brakes, electromagnetic clutches and zero-backlash clutch couplings. If a standard catalog item doesn't fit your need our products can be modified to your specifications. We work closely with our customers, from assisting with the selection of a single key component to building a fully integrated system capable of meeting all your requirements.

Precision Magnetic Particle Brakes

AVAILABLE IN:

Voltage: 24 V dc
Torque Range: .06 - 115 lbf in.
Length: 2.10 - 5.53 in.


Magnetic Particle Brakes are ideal for tension control applications and high cycle applications such as labeling machines for the food and drug industry. Their operating torque range is broad and can be very accurately controlled. Standard catalog units have a voltage of 24V DC, other voltages are available on special order.










PRECISION SHAFT-MOUNTED CLUTCH COUPLINGS:




Precision Electromagnetic Clutch Couplings

AVAILABLE IN:

Voltage: 24 V dc
Static Torque: 5 - 80 lb-in.
Bore Size: 0.25 in. - 0.50 in.


Shaft-Mounted Clutch Couplings are designed for inline loads. Standard voltage is 24V DC, other voltages and dissimilar bore combinations are available as special order.
