The BRIDGEPORT 12193427 is a trip assembly lever designed as a replacement part for Bridgeport milling machines. The trip assembly lever is a mechanical component involved in the knee, quill, or table travel stop function, allowing the operator or machine mechanism to disengage or halt axis movement at a set position. Installation and replacement of this part is typically performed by a machine tool technician or millwright during scheduled maintenance or after component wear. This is an OEM-style replacement part sold individually.
This trip assembly lever is intended for use in manual and manual-assist Bridgeport-style vertical knee milling machines found in machine shops, tool rooms, and light manufacturing environments. It is a direct service replacement for worn or damaged lever assemblies and is sold as a single-piece unit. This part is suited for facilities that maintain their own machine tool equipment in-house.
Designed as an OEM-style replacement lever component for Bridgeport vertical knee milling machines. No specific model numbers or system families were provided in the product data. Verify fitment against your machine serial number and parts diagram before ordering.
Installation should be performed by a qualified machine tool technician or millwright. Before beginning any service work, power down the machine completely and follow lockout/tagout procedures in accordance with applicable OSHA standards. Refer to the machine's original parts manual and exploded diagram to confirm correct positioning and hardware torque requirements. Do not operate the machine until all trip and stop functions have been verified for correct engagement.
