Climax Metal Products C733M-75 Shaft Locking Device

Product Description

The CLIMAX METAL PRODUCTS C733M-75 is a shaft locking device engineered for secure mechanical power transmission in industrial and heavy-duty rotating equipment. It locks a shaft to a hub or bearing housing without requiring keyways or splines, using a clamping action distributed across 7 screws. The bore diameter is 75mm with an overall outside diameter of 5.433 inches and an overall assembled width of 5.433 inches. The thrust ring width measures 0.984 inches. Rated for an axial load of 33,151 pounds and a maximum torque of 4,079 foot-pounds, this device is suited for demanding drive applications where precise, repeatable shaft retention is required.

The C733M-75 is used in industrial machinery, conveyor systems, gearbox assemblies, pump drives, and fan shaft installations where positive shaft locking is necessary. It is appropriate for both OEM manufacturing builds and field replacement in maintenance and repair operations. M8 thread fasteners are used for clamping engagement, making tooling straightforward for millwrights and mechanical technicians working in plant environments.

Key Features

• 75mm bore diameter for direct shaft engagement without keyways
• 33,151-pound axial load rating for heavy-duty applications
• 4,079 foot-pound maximum torque capacity
• 7-screw clamping design for even load distribution around the shaft
• M8 thread size for clamping screws
• 0.984-inch thrust ring width for axial positioning control

Compatibility

Designed as an OEM-style replacement or direct-fit shaft locking device for industrial rotating equipment with a 75mm shaft diameter requiring external mechanical locking without keyway modifications.

Installation Notes

Installation and removal should be performed by a qualified millwright or mechanical technician. De-energize and lock out all power to the connected equipment before beginning work. Tighten clamping screws in a gradual, cross-pattern sequence to ensure even clamping force around the shaft circumference. Follow ANSI and applicable machinery safety standards for torque procedures and lockout/tagout compliance.
