Excellent wear resistance of wheel rim:The rims of the supporting wheels are made of advanced wear-resistant materials and are precision-machined to ensure that they maintain good wear resistance under long-term, high-load operation. This not only prolongs the service life of the wheel, but also reduces downtime due to wear and tear and improves overall work efficiency.Excellent high temperature resistance:The supporting wheel is made of special high temperature resistant material, which can maintain stable performance under high temperature environment. This excellent high-temperature resistance enables the supporting wheel to operate normally under extreme working conditions without being affected by temperature, thus ensuring the continuous and efficient operation of the equipment.Wooden box independent high-end packaging, highlighting the noble quality:Each supporting wheel is packed in an independent wooden case with a high-end and elegant design, which not only protects the product from damage during transportation, but also highlights the noble quality of the product. This meticulous packaging not only reflects our treasure and respect for the products, but also provides customers with a more convenient and safer transportation and storage experience.

• 【Size】:Tensile strength σb (MPa): ≥450,Yield strength σ0.2 (MPa):≥310,Hardness:160 ~ 210 hb
• 【Fits For】:Fit for John Deere 35D Excavator
• 【Reliable bearing sealing technology】The advanced bearing seal design of our support wheels effectively prevents the intrusion of dust, moisture and other impurities, thus ensuring cleanliness and lubrication inside the bearings. This reliable sealing technology greatly reduces the wear and tear of the bearings and ensures smooth operation and long durability of the wheel.
• 【Extremely low rolling resistance】The rolling design of the support wheel has been optimized to achieve extremely low rolling resistance. This not only reduces energy consumption and improves the working efficiency of the equipment, but also makes the wheel run more smoothly and stably, reduces the heat and noise generated by friction, and improves the overall experience of using the wheel.
• 【High hardness material forged tough quality】The main part of the supporting wheel is made of high hardness alloy material, which is precision cast and heat-treated to give it high strength and hardness. This tough quality makes the supporting wheel able to withstand greater loads and impacts, ensuring the stability and safety of the equipment.
