BM500 Front Idler Application
The BM500 front idler is a guide component in the crawler crane travel system. It works together with the track rollers, carrier rollers, drive sprocket, and track shoes to keep the chain moving in the correct path. If the idler surface, shaft area, or rim profile is worn, the machine may show loose track movement, side wear, abnormal noise, or repeated tension adjustment problems.
As a Track crane front idler supplier, SQ focuses on matching the part according to real installation information, not only by model name.

Why Correct Idler Fitment Matters
A crawler crane idler may look simple, but its dimensions affect the entire track system. The outer diameter, width, shaft size, rim shape, and adjuster connection should be checked before supply. A mismatched idler can increase wear on the track chain, track rollers, and sprocket.
Focused BM500 matching: Suitable for Kobelco BM500 crawler crane undercarriage repair and replacement.
Fitment verification before supply: Photos, samples, drawings, and dimensions can be reviewed to reduce wrong-part risk.
Suitable for repair and stock: Useful for crane owners, service teams, rental fleets, and parts distributors.
Supply Support for Crawler Crane Undercarriage Parts
SQ supplies replacement crawler crane undercarriage components for repair and maintenance markets. As a Crawler crane undercarriage parts manufacturer, we can help customers check idlers, rollers, sprockets, and track shoes according to machine model, part number, drawing, or physical sample.
Although this page focuses on Kobelco BM500 idler, customers who source parts for mixed fleets may also ask for other crane track components. For example, Hitachi crane track shoes can be checked separately by shoe width, pitch, bolt hole layout, and machine model. Keeping each inquiry item with clear dimensions helps improve quotation accuracy.
How to Confirm the Correct BM500 Crane Idler
To confirm the right idler, please take clear photos of the old part from the front, side, shaft area, and mounting position. Useful measurements include idler outside diameter, total width, shaft or bore size, rim profile, and adjuster connection details. If the old part is damaged, a drawing or physical sample can help with comparison.
