Overview
The Ruland 45mm two-piece shaft collar is a precision clamping component designed for power transmission and mechanical alignment in industrial machinery. This metric bore shaft collar clamp features a split design that allows easy installation and removal without damaging the shaft, making it ideal for applications requiring frequent adjustments or repositioning.
Key Features
- Two-piece clamp-style design — does not mar the shaft and is indefinitely adjustable
- Metric bore — 45mm bore diameter with tight perpendicularity control (TIR ≤ 0.5mm)
- Easy disassembly — split design for quick installation, removal, and repositioning without tools
- Superior holding power — proprietary manufacturing processes ensure fit, finish, and secure clamping
- Versatile applications — commonly used for guiding, spacing, mechanical stops, mounting, and component alignment
