Bradken Front Idlers
The Bradken Front Idlers are engineered to provide exceptional performance and durability for hydraulic excavators used in mining applications. With a hardened roller path and engineered alloy, these idlers are designed to minimise stress concentration within the transition zone.
Bradken Front Idlers
Specifications
- Bradken Front Idlers are designed with an induction-hardened roller path that provides excellent wear resistance.
- They are made with a high-strength proprietary Bradken induction-hardening alloy and a hardened depth of typically 15-20 mm.
- The use of an engineered alloy with a greater depth and stringent process control minimizes stress concentration within the transition zone.
- The idlers feature AISI 4340 axles with ground, induction-hardened running surfaces, which prevent galling and maximize resistance to impact loading.
- Cross-hatched lubrication grooves in the idler's bushes eliminate axle flats that can cause premature internal wear and increase their typical life expectancy.
