Climax Metal Products C193E-031 Shaft Locking Device

Product Description

The CLIMAX METAL PRODUCTS C193E-031 is a shaft locking device designed to secure rotating shafts against axial movement in mechanical drive and power transmission assemblies. It features a 5/16 inch bore diameter and a 7/8 inch outer diameter, with an M4 thread size and a three-screw clamping configuration. The overall width measures 1 inch, and the thrust ring width is 0.394 inches. Rated for an axial load of 1,643 pounds and a maximum torque of 257 ft-lb, this collar-style locking device is built for demanding shaft retention applications. Installation is typically performed by mechanical or industrial maintenance technicians.

This shaft locking device is suited for use in small-bore shaft assemblies where precise axial positioning and secure locking are required. Common applications include light industrial machinery, mechanical drive systems, and equipment where shaft collars must resist both axial thrust and rotational forces. The compact 5/16 inch bore size makes it appropriate for smaller-diameter shafts found in motors, pumps, and conveyor systems.

Key Features

• 5/16 inch bore diameter and 7/8 inch outer diameter for compact shaft fitment
• M4 thread size with three-screw clamping configuration for secure, even load distribution
• 1,643 lb axial load rating suitable for demanding mechanical applications
• 257 ft-lb maximum torque capacity
• 1 inch overall width with 0.394 inch thrust ring width for space-efficient installation
• Lightweight at 0.1 pounds for use in weight-sensitive assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit shaft locking device for mechanical drive assemblies requiring a 5/16 inch bore, 7/8 inch OD, M4-thread collar with three-screw retention.

Installation Notes

Installation should be performed by a qualified mechanical technician familiar with shaft collar and locking device procedures. De-energize and lock out all drive equipment before installing or removing the collar. Use a calibrated torque tool when tightening the M4 clamping screws to achieve even clamping force across all three screw positions. Verify shaft surface condition and cleanliness before seating the collar to ensure rated axial load performance.
