Pin Riveting

Pressed four times for an extra strong rivet that resists powerful lateral forces on the outer plate

4
2

Solid Bush

Solid bushes provide enhanced resistance to distortion from repetitive shock loading

Riveted Bush

All 520 HDR/HDS/X1R/X1R2 have riveted bushes that resist powerful lateral forces on the inner plate

X-Ring Seal

X-Ring seals offer better sealing than the conventional O-Ring and produce far less friction. All Z3/X1R chains are equipped with X-Rings
