Overview
The Stafford 2L300HD is a 3″ steel two-piece clamp-type shaft collar built for heavy-duty industrial applications. This precision-engineered collar combines disassemblability with exceptional holding power, making it ideal for applications requiring secure, adjustable shaft positioning. The heavy duty designation indicates enhanced clamping force through a larger diameter and upgraded clamping screw mechanism.
Key Features
- 2X Holding Power: Heavy duty design with larger clamp screw and outside diameter provides double the holding power of standard styles
- Precision Machined: Non-marring finish protects shaft surfaces from damage during installation and adjustment
- Easy Adjustment: Simple screw mechanism allows tool-free positioning and repositioning anywhere along the shaft
- Completely Disassemblable: Two-piece split design enables installation and removal without disassembling surrounding equipment
- Versatile Mounting: Works on standard round shafts, hardened or soft material, thin-wall tubing, and split hub applications
- Steel Construction: Durable carbon steel material provides long service life in demanding mechanical environments
