REMPCO manufactures mechanical levelwind components in standard and custom lead sizes to meet your specific spooling needs. Levelwinds may also be commonly referred to as self-reversing screws or diamond screws.

Rempco’s mechanical levelwinds are generally more reliable than hydraulically or electrically driven alternatives since there is less to go wrong. Adjusting for different cable sizes or spacing is as simple as changing the drive gear ratio.

Common applications include coiled tubing reels for oilfield equipment and umbilical cable winches for offshore platforms and shipboard use.

Our diamond screws range in diameter from 0.75 inches (20 mm) to 6.0 inches (150 mm) and are available in high-tensile, corrosion resistant materials including ATEX compliant materials. All components are tested for self-reversing functionality in specially made fixtures. This ensures trouble-free operation. For all your industrial replacement parts, turn to REMPCO. We work hard to locate the spare parts you need, or customize a solution that works for you.
