ASCIUTTA Track Roller Bottom Roller Undercarriage for CAT 304DCR 304ECR 303.5ECR/CCR 303CCR 302.5C

Key features

• Reliable bearing sealing technologyThe 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.
• Fits For:Bottom Roller For CAT 304DCR 304ECR 303.5ECR/CCR 303CCR 302.5C
• FunctionalThis bottom roller is a durable undercarriage replacement part for your excavator. Our rollers utilize special high strength-hardened steel and quality seal groups that provide excellent lubricating oil retention.
• High hardness material forged tough qualityThe 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.
• Extremely low rolling resistanceThe 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.
