Shaft-Mounted Clutch-Brake
LSCB-44
Nexen’s through-shaft, air-to-spring clutch-brake is the
ideal solution for repetitive start/stop conveying
applications. Mounted on the roller shaft of an
accumulating conveyor, LSCB clutch-brakes provide
positive stopping and holding. Nexen’s splined hub
design assures full brake torque to the system. Both
clutching and braking components utilize the same
piston to eliminate simultaneous engagement.
Because the clutch release springs also serve as the
brake engagement force, the brake automatically
engages as the clutch releases for fast, dependable
stopping and holding. Combining simple design,
outstanding performance and low cost, the LSCB-44
is the obvious choice for motion control on material
handling conveyor systems.

• Clutch Torque: 238 Nm at 5.5 bar [2110 in-lb at 80 psi]
• Brake Torque: 6.3 Nm [56 in-lb] at zero air pressure
• Bore range: 12-32 mm [0.500-1.250 in]
• Single piston design eliminates possibility of clutch-brake overlap
• Brake engagement stops LSCB hub
• Variable mounting configurations: customer supplied sprocket or can be
configured for sheave, plate or double-single sprocket or timing belt
sprocket
• Open design for improved airflow and high heat dissipation
• Internal spline drive for trouble-free disengagement performance
• Shielded ball bearings standard for zero drag torque– shear modulus of
bearing grease creates negligible drag torque (sealed bearings also
available)
• No rotary air union required
• Field repairable o-rings, facings and springs
• Through-shaft design with three set screws for easy mounting
