Shaft Collar 1-1/8in

The Shaft Collar 1-1/8in from Allstar Performance is an essential mechanical component designed for precision applications where axial positioning and load transfer are mission-critical. Whether you're assembling high-performance machinery, rebuilding tactical equipment, or maintaining specialized systems in law enforcement or military settings, this shaft collar provides reliable shaft retention and alignment. The 1-1/8 inch bore diameter makes it compatible with standard industrial and performance-grade shaft systems commonly found in equipment requiring repeatable, zero-play positioning.

Built by Allstar Performance—a manufacturer trusted in high-demand environments—this shaft collar features a precision-machined design that locks securely onto 1-1/8 inch shafts without damaging the surface. The collar's compact profile (measuring 4.05 x 0.7 x 7.05 inches) and lightweight construction (0.13 lbs) allow for installation in space-constrained assemblies without compromising structural integrity. The set-screw locking mechanism ensures repeatable, tool-free adjustment and re-positioning when service or component swap-outs are required, making it ideal for modular systems where frequent reconfiguration is necessary.

Professionals in equipment maintenance, powersports assembly, and industrial repair rely on this collar for applications ranging from pump rebuilds to precision machinery setup. Installation is straightforward: slide the collar onto the shaft and tighten the set screw until resistance is felt, then back off slightly to avoid over-torque. This design is ideal for technicians who need a repeatable, non-permanent shaft retention solution that won't slip under operational load, making it equally suitable for field repairs and bench work where durability and ease of maintenance are
