Overview
The TB Woods L07558 is a precision-engineered L-Jaw coupling hub designed for light- to medium-duty industrial power transmission. Built from sintered carbon steel with a straight jaw profile, this L075-size hub accommodates a 5/8″ diameter shaft and provides reliable torque coupling up to 227 in-lbs. The finished bore includes a 3/16″ × 3/32″ keyway and set screw clamping for secure shaft locking.
Key Features
- Sintered carbon steel construction ensures durability and corrosion resistance in harsh industrial environments
- Straight jaw design optimized for smooth power transmission with minimal backlash
- Set screw clamping simplifies installation and maintenance without requiring special tools
- Maximum speed rating of 11,000 RPM accommodates high-speed machinery applications
- Finished bore with 1/4-20 UNC-2B set screw provides positive shaft retention
