Overview
The Dodge PX70 taper-lock flange assembly is a precision-engineered mechanical coupling component designed for industrial power transmission applications. Manufactured by Dodge (a division of Baldor), this flange assembly features a taper-lock bushing interface for secure shaft attachment and accommodates the 1610 bushing size. The sintered steel construction provides durability and consistent torque transmission, making it ideal for machinery requiring reliable, low-maintenance shaft coupling solutions.
Key Features
- Elastomeric tire coupling — absorbs shock and misalignment without lubrication
- Taper-lock bushing design — quick installation and removal with no keyways required
- Sintered steel flange — corrosion-resistant, long service life
- Close-coupled shaft spacing — compact mounting footprint
- Wide temperature range — rated –45 °F to 180 °F
- ATEX certified — compliant for use in hazardous environments
