If your machine feels unstable or you hear a grinding noise while traveling, it’s likely time for a replacement track roller. As the primary load-bearing component of your undercarriage, the bottom roller (or lower roller) supports the full weight of the excavator while guiding the track chain across uneven terrain. BeeSpareParts provides precision-forged track roller assemblies designed to resist extreme abrasion and prevent costly downtime.
A seized or leaking track roller can quickly lead to "flat spots" on your track links, significantly accelerating wear across the entire system. To ensure maximum performance, we recommend checking your if you notice track sag, or inspecting your for pitch elongation. Our heavy-duty track rollers are direct-fit alternatives to OEM parts, featuring induction-hardened steel shells and high-performance dual-cone seals to keep lubricants in and contaminants out.
Whether you need a lower roller for a 20-ton Komatsu, a mini-excavator roller for a Cat, or replacement bolts, our parts are factory-tested for load capacity and ready for fast international shipping. Keep your machine moving efficiently—order your premium track roller solutions today.
