The LEJB is a belt driven slider type electric actuator available exclusively with an AC servo motor. The actuator features a substantially wider load mounting platform than the LEFB, supported internally by a double axis linear guide for reduced moment deflection. The AC servo motor enables higher speed and acceleration. LEJB's belt drive allows longer strokes and higher speeds than the LEJS
