Bradken Load Rollers

Bradken Load Rollers Specifications

Specifications

• The design overcomes problems in traditional Caterpillar load rollers by introducing an independent axle for machine weight support.
• Internal bearing surfaces are mostly lubricated, minimizing wear and lowering operating temperatures.
• The combination of features reduces the rate of wear, maximizes contact area and reduces axle bending.
• The roller shell is made of AISI 4340 with good hardenability and superior resistance to impact loading.
• The roller path is induction hardened to typically 500 BHN.
• The roller shell is forged for superior mechanical properties in the direction of roller loading.
• It has a hardened depth typically of 25 - 30 mm.
• The rollers have increased lubrication capacity, and AISI 4340 axles with ground, induction hardened running surfaces to minimize galling and maximize resistance to impact loading.
