MSU / MSCP

Installation and Instruction Manual

The Ogura model MSU is an inline shaft unit in which the MSC type clutch and MSB

type brake are accurately centered and set in a light alloy housing, and is ideal for repeated

start and stop. The MSCP type has only the clutch set in the same way as the MSU type. All of

them are stationary type and have input / output shafts, so they can be easily connected

directly by coupling or driven by belt pulleys. In addition, it has a large heat dissipation capacity,

can withstand high frequency use, and the gap is kept constant by the auto gap device only by

applying the exciting voltage, so no adjustment is required after installation.
