Climax Metal Products C133E-243 Shaft Locking Device

Product Description

The CLIMAX METAL PRODUCTS C133E-243 is a shaft locking device designed to secure rotating shafts to hubs, collars, or other mechanical components without keyways or set screws. It features a 2-7/16 inch bore diameter and a 3.74 inch outer diameter, with M8 thread screws providing uniform clamping force across the assembly. Nine clamping screws deliver an axial load capacity of 20,836 pounds and a maximum torque rating of 2,116 ft/lb, making it suitable for demanding power transmission applications. This device is installed by mechanical maintenance technicians and millwrights in industrial and commercial equipment settings.

The C133E-243 is appropriate for use in conveyor drives, pump shafts, fan assemblies, and other rotating equipment where precise shaft-to-hub locking is required without machining a keyway. The 4.016 inch overall width and 0.787 inch thrust ring width allow it to fit within standard mechanical drive envelopes. It is commonly used in both new installations and replacement scenarios on industrial machinery requiring reliable torque transmission and axial load control.

Key Features

• 2-7/16 inch bore diameter accommodates standard shaft sizes in industrial drive applications
• 3.74 inch outer diameter fits common hub and housing configurations
• 9 M8 thread clamping screws provide even load distribution around the shaft
• 20,836 pound axial load capacity supports heavy-duty power transmission
• 2,116 ft/lb maximum torque rating for high-torque drive systems
• 0.787 inch thrust ring width and 4.016 inch overall width for compact installation

Compatibility

Designed as an OEM-style shaft locking device for industrial rotating equipment with a 2-7/16 inch shaft diameter requiring keyless friction-based locking.

Installation Notes

Installation is typically performed by millwrights or mechanical maintenance technicians. De-energize and lock out all power sources before servicing any rotating equipment per OSHA lockout/tagout procedures. Clean shaft and bore surfaces before installation to ensure full contact and proper clamping. Tighten the M8 screws in a star pattern to achieve even clamping force; consult the manufacturer torque specification sheet for final fastener values.
