Climax Metal Products C193M-8 Shaft Locking Device

Product Description

The CLIMAX METAL PRODUCTS C193M-8 is a shaft locking device designed to secure rotating components to shafts in mechanical power transmission applications. It features an 8mm bore diameter and a 7/8 inch outer diameter, making it suited for compact drive assemblies where space is limited. The device uses three M4 screws to clamp the thrust ring against the shaft, developing an axial load capacity of 1,643 pounds and a maximum torque rating of 259 foot-pounds. Overall width is 1 inch, with a thrust ring width of 0.394 inches. This type of locking collar is installed and serviced by mechanical technicians and industrial maintenance professionals.

The C193M-8 is used in industrial and commercial machinery where shafts must be positively located against axial movement. Typical applications include gearboxes, conveyors, pumps, and other rotating equipment requiring a reliable shaft retention method. Its M4 thread size and 8mm bore suit metric-dimensioned shaft systems common in imported or OEM industrial equipment. The compact outer diameter allows installation in confined bearing housings or tight frame assemblies.

Key Features

• 8mm bore diameter with 7/8 inch outer diameter for compact fitment
• M4 thread size compatible with metric fastening systems
• Three-screw clamping design for balanced axial load distribution
• 1,643 pound axial load capacity for positive shaft retention
• 259 foot-pound maximum torque rating
• 0.394 inch thrust ring width with 1 inch overall width

Compatibility

Designed as a replacement or new-installation shaft locking device for metric-bore rotating shaft assemblies requiring an 8mm bore, 7/8 inch outer diameter, and M4 thread fasteners.

Installation Notes

Installation should be performed by a qualified mechanical technician. Ensure the shaft and mating equipment are fully de-energized and locked out before installing or removing the locking device. Tighten the three clamping screws evenly in a cross pattern to achieve uniform load distribution across the thrust ring. Follow applicable machinery safety standards and the equipment manufacturer guidelines for shaft retention hardware.
