Overview
The 8386K26 shaft collar is a two-piece clamp-style collar manufactured for reliable shaft retention in industrial machinery and motion control applications. This unbranded unit features a 1-3/8″ bore diameter paired with a 2-1/4″ outer diameter, making it suitable for mid-range shaft sizes in conveyor systems, pump drives, and power transmission assemblies. The black oxide finish provides corrosion resistance and a professional appearance.
Key Features
- Two-Piece Split Design — Easy installation without removing the shaft; ideal for retrofit and maintenance applications
- Clamp-Style Operation — Distributes clamping force evenly without marring or scoring the shaft
- Black Oxide Finish — Corrosion-resistant coating extends service life in industrial environments
- Precise Bore Dimensions — 1-3/8″ bore engineered for secure, repeatable positioning
- Compact Profile — Minimal axial width (9/16″) allows use in space-constrained applications
