Excavator Teeth Near Me 1070-Z8190LR for VOLVO 55 SIDE CUTTER ( 3HOLES) Replacement Parts

What is the lifespan of the edge teeth of the 1070-Z8190LR?

The lifespan of the edge teeth of 1070-Z8190LR is influenced by multiple factors. The specific analysis is as follows:

1. Youdaoplaceholder0 Materials and design factors ‌

If the edge teeth are made of high-strength alloy steel (such as 20CrMnTi) and undergo carburizing and quenching treatment, their contact fatigue limit can reach over 2000MPa, and their service life is usually over 10 years ‌.

Edge teeth made of common carbon steel (such as Q235) have a relatively low fatigue resistance, and their service life may be shortened to 5-8 years ‌.

2. Youdaoplaceholder0 operating conditions affect ‌

Load conditions ‌ : Long-term overloading operation (such as a designed load of 10kN but actually reaching 15kN) will significantly shorten the service life, possibly reducing it by 30% to 50%‌.

Lubrication condition ‌ : Insufficient oil film thickness or deterioration of lubricating oil may cause direct metal contact, accelerate wear, and reduce service life by 40%-60%‌.

3. Youdaoplaceholder0 Maintenance and usage habits ‌

Regular inspection of tooth surface wear (such as pitting and spalling) and timely replacement of damaged parts can extend service life ‌.

Avoiding impact loads (such as hard material jamming) can reduce the risk of tooth breakage ‌.

4. Youdaoplaceholder0 typical lifespan range ‌

Under normal operating conditions (medium load and good lubrication), the service life of the edge teeth of 1070-Z8190LR is typically ‌8 to 12 years ‌. Under harsh conditions, it may be shortened to 3-5 years ‌.

It is recommended to optimize life ‌ through regular lubrication, load monitoring and material upgrading.
