Function
This outer bushing, also named frame bushing, is a precision‑engineered core frame‑mounted cone crusher part exclusively designed for Symons cone crushers, fully compatible with 3FT, 4FT, 4.25FT, 5.5FT and 7FT models. As an essential Symons cone crusher spare part installed in the crusher frame assembly, this frame bushing bears heavy‑load rotational friction, radial pressure and continuous dynamic impact during mining, quarrying and aggregate crushing. The optimized oil‑groove structure greatly improves internal lubrication efficiency, reduces abrasion between mating cone crusher parts and frame components, and ensures long‑term stable operation of Symons cone crusher core frame assembly under severe heavy‑duty working conditions. We provide a full range of Symons cone crusher spare parts and complete cone crusher parts solutions, including outer bushing (frame bushing), socket liner , inner bushing, countershaft bushing ,upper and lower step plate and other wear‑resistant components to meet customers’ one‑stop replacement and procurement needs for Symons crushing equipment.
Compatibility
Precision‑manufactured to perfectly fit all mainstream Symons cone crusher models: 3FT, 4FT, 4.25FT, 5.5FT, 7FT.
