Overview
The Ruland 6435K74 is a precision-engineered one-piece shaft collar designed for mechanical power transmission and industrial automation. This 2-7/16″ diameter collar is constructed from 1215 lead-free steel with a black oxide finish for durability and corrosion resistance. As a clamp-style collar, it wraps around the shaft for even clamping forces and reliable holding power without marking or damaging the shaft surface.
Key Features
- One-Piece Clamp Design: Easier to adjust, remove, and reposition than split-design alternatives
- Precision Steel Construction: Made from North American 1215 lead-free steel with black oxide finish
- Even Clamping Force: Wraps completely around shaft for balanced load distribution
- Shaft-Safe Operation: Clamp mechanism eliminates shaft marring caused by set screws
- USA Manufactured: Precision-engineered and produced in Marlborough, MA under strict controls
- Compliance: RoHS3, REACH, and Conflict Minerals compliant
