FAQ

Q1: Why is impact resistance important for an excavator idler?

Excavators frequently operate on rough terrain and experience repeated shock loads. A high-impact-resistant idler maintains its structural integrity under these conditions, reducing the risk of deformation and unexpected downtime.

Q2: How does a hardened raceway improve service life?

The induction-hardened raceway provides a highly wear-resistant contact surface that minimizes abrasion and rolling fatigue while maintaining a tough core capable of absorbing heavy loads.

Q3: What role does the floating Duo Cone seal play?

The floating seal keeps lubricant inside the bearing chamber while preventing dust, mud, water, and abrasive particles from entering, helping to reduce internal wear and extend bearing life.

Q4: Is this ZAX240 idler suitable for mining and quarry applications?

Yes. It is specifically designed for demanding environments including mining, quarrying, construction, demolition, and earthmoving operations where heavy loads and abrasive conditions are common.
