Regina 520 ZRE Z-Ring Chain

The new, high-performance, outstanding ZR chains take a big step forward with the new patented Z44 seal rings. These new generation seal rings, which feature a special-designed conical shape on their inner side, are the result of the evolution of previous X-ring and Z-ring designs.

Features:

• Patented “Z” ring section.
• The Z-ring flexes when assembled, creating a spring effect that guarantees the seal will not diminish over time.
• The special Z-ring section provides enhanced chain flexibility.
• The lubricant trapped between the plates and the lobes of the Z-ring keeps the ring lubricated and increases its life.
• ZR chains are the best choice for the most severe and demanding applications. Among other characteristics, the ZR chains feature high alloy steel plates and pins, solid bushings and rollers, shot-peening of plates, pins and rollers, performance-enhancing pre-stretching and “gold” outer plates.
