Overview
The Rexnord 1990X2-A is a shaft-mounted speed reducer assembly with integrated tie rod construction, purpose-built for compatibility with the 107TR and 115TR Link-Belt reducer product family. This assembly delivers precision speed control and torque management across demanding industrial applications. Rexnord engineered this component to meet exacting standards for alignment and vibration damping, critical in conveyor systems, drive equipment, and rotating machinery requiring stable speed reduction.
Key Features
- Tie Rod Assembly Design — Provides precise alignment and mechanical stability under load, reducing vibration and extending bearing life in shaft-mounted configurations.
- Shaft-Mounted Configuration — Direct coupling to output shafts simplifies integration and eliminates external mounting frames, reducing installation footprint.
- Link-Belt Series Compatibility — Engineered for seamless operation with 107TR and 115TR reducer housings, ensuring drop-in compatibility and maintained performance tolerances.
- Industrial-Grade Durability — Manufactured from high-strength materials to withstand continuous duty cycles and harsh industrial environments.
- New in Box Condition — Supplied factory-sealed with no prior service history, ensuring immediate deployment without rebuild or inspection delays.
Technical Specifications
Verify exact specifications with Rexnord documentation or your system integrator, as configurations vary by application and load rating.
Typical Applications
- Conveyor Drive Systems — Shaft-mounted reducers for belt and chain conveyor speed control and load distribution.
