FAQ
Q1: What is the function of a KX35 carrier roller?
The carrier roller supports the upper section of the track chain, helping maintain proper chain movement, reduce track sag, and improve overall undercarriage stability.
Q2: How does high wear resistance improve carrier roller performance?
A wear-resistant roller surface reduces abrasion caused by continuous track chain contact, helping extend service life and reduce replacement frequency.
Q3: Why is load bearing performance important for a carrier roller?
The carrier roller supports the weight and movement of the upper track chain. Superior load capacity helps maintain stable operation and prevents premature component failure.
Q4: Is the KX35 carrier roller suitable for compact excavators?
Yes. It is specifically designed for KX35 mini excavators and is suitable for construction, landscaping, utility, and earthmoving applications.
