Climax Metal Products C193E-037 Shaft Locking Device

Product Description

The CLIMAX METAL PRODUCTS C193E-037 is a shaft locking device designed to secure rotating components to shafts in mechanical assemblies. It features a 3/8 inch bore diameter and a 15/16 inch outer diameter, making it suited for compact drive and motion control applications. The device uses three M4 threaded screws to generate clamping force, delivering a rated axial load capacity of 1,643 pounds and a maximum torque rating of 308 foot-pounds. Overall width measures 1-1/16 inches, with a thrust ring width of 0.394 inches. This type of collar is typically installed by mechanical technicians and maintenance professionals working on conveyor systems, gearboxes, motors, and similar rotating equipment.

The C193E-037 is appropriate for use in light to medium industrial machinery where precise shaft retention and axial load management are required. Its three-screw configuration distributes clamping force evenly around the shaft, reducing the risk of shaft scoring or collar slippage under load. It is suited for both new installations and maintenance replacements on equipment with 3/8 inch shaft diameters requiring a compact locking collar form factor.

Key Features

• 3/8 inch bore diameter for direct shaft mounting
• 15/16 inch outer diameter for compact installation envelopes
• Three M4 screws provide balanced radial clamping force
• 1,643 pound axial load capacity for medium-duty retention
• 308 foot-pound maximum torque rating
• Thrust ring width of 0.394 inches for precise axial positioning

Compatibility

Designed as an OEM-style replacement or new-installation shaft locking collar for mechanical assemblies with a 3/8 inch shaft diameter and M4 threaded fastener requirements.

Installation Notes

Installation is typically performed by a qualified mechanical technician or millwright. Before mounting, de-energize and lock out the equipment per applicable OSHA lockout/tagout procedures. Clean the shaft surface and bore of any debris or burrs before seating the collar. Tighten the M4 screws evenly in a cross pattern to achieve uniform clamping force without distorting the collar.
