PINS

Alloy or premium grade carbon steel.
Heat treated for superior strength and toughness.
- Core – Through hardened for superior impact resistance.
- Surface – Case or Induction hardened for extended wear resistance.
Precision manufactured to maintain high interference fit with sidebars.
- Prevents pin rotation and subsequent sidebar wear.

BUSHINGS

Alloy or premium grade carbon steel.
Heat treated for superior strength.
- Core – Through hardened for toughness/impact resistance.
- Surface – Case hardened for ultimate/extended wear resistance.
Precision machined to maintain smooth bearing surfaces and high interference fit with sidebars.
- Favorable residual stresses resist fatigue and allow for extended life.

SIDEBARS

Alloy or premium grade carbon steel.
Through hardened for superior strength, toughness and fatigue resistance.
Proprietary manufacturing processes ensure consistent hole quality and precise pitch control.
- Favorable residual stresses resist fatigue and allow for extended life.
