L276 Jaw Coupling Hub — Pilot Bore
The L276 Coupling Hub is a precision-manufactured industrial jaw-type coupling element designed for reliable, fail-safe power transmission. Featuring a standard pilot bore, this hub serves as a versatile baseline that can be easily customized, re-bored, and machined to match your exact shaft diameter requirements.
Key Features & Advantages
- Pilot Bore Versatility: Delivered with a minimal starting bore size to allow custom machining for a precise fit on your specific motor or driven shaft.
- Fail-Safe Design: Engineered to remain functional even if the elastomeric spider element degrades, preventing catastrophic machine stoppage.
- Robust Construction: Crafted from high-strength materials optimized to resist shock loads, wear, and structural fatigue in standard operating environments.
- Easy Alignment & Setup: Straightforward configuration simplifies multi-directional misalignment adjustment during assembly.
