Compatible Replacement Parts for Symons Cone Crushers

A classic design that still earns its keep

The Symons design — spring tramp release, a steep chamber, and mechanical setting adjustment — defined cone crushing for generations, and the machines refuse to retire. Quarries and mines keep them on secondary and tertiary duty because the frames last and the duty is understood. The challenge is purely logistical: as the installed base ages, owners need mantles, concaves and mechanical spares from a supplier who still treats the design as a live product line rather than a legacy favour — with no part line recorded against Symons sizes in our catalogue — the recorded lines stand against specific HP sizes and the GP220 only — so each part for these machines is confirmed against its size and original part number. That is the role of this page.

Parts coverage

The chamber wear lines — mantles and concaves / bowl liners in manganese steel — and the mechanical lines — heads, main shafts, countershaft components, eccentric bushings, gears, frames, sockets, springs and hardware — are general catalogue lines under the crusher spare parts catalogue. None of them is recorded against Symons sizes in the catalogue: for a Symons machine, each part is confirmed against the machine size and the original part number when quoted, not assumed from the general programme. Where one of these lines also stands on record elsewhere in the catalogue — gears and main frames among them — that record stands against its named HP size only, and never against Symons or against the GP series; the only GP-series records in the catalogue are the GP220 upper frame and the GP220 top bearing, recorded against the GP220 only. Spring-side components deserve a specific mention: on a spring crusher, the spring pack is the tramp protection, and tired springs change the machine's crushing behaviour long before anything breaks — which is why the springs on a Symons enquiry are confirmed by size and part number like every other line, rather than treated as covered.

Identifying parts for an older machine

Symons machines in the field span decades of production, and part identification is where orders succeed or fail. The reliable identifiers are the machine size, the original part number from the manual or the old part, and — where documents are gone — dimensions from the worn component itself. Send photographs with a scale reference and the key measurements you can take; we will work through identification with you before quoting, because a Symons-era part made to the wrong generation's drawing helps nobody. This measured approach is the same one set out in our guide to the cone crusher's components and how they wear.

Ordering

Minimum order 1 piece on a confirmed line, confirmed with your quotation. Lead time is confirmed per quotation — cast wear parts for less common sizes are produced to order, and the quote says so plainly rather than promising stock that does not exist. Shipment FOB, EXW, CIF or FCA; payment T/T or L/C. If you run Symons machines alongside newer HP or other cone crushers, consolidate the enquiry: the same order can carry compatible parts for each, under one fit-confirmation process — with no part line recorded against Symons sizes — the recorded lines in the catalogue stand against specific HP sizes (bowls, head assemblies, gears, main frames and clamping rings) and against the GP220 (the upper frame and the top bearing) only, and none of them is recorded against Symons — so every part in the order is confirmed against its own machine's size and original part number.

Keeping a spring-cone fleet economic

Owners of Symons-design crushers make the same calculation every year: the machines still crush, the frames are sound, so the question is purely whether parts economics continue to favour running them. Two habits keep the answer yes. The first is wear-set discipline — mantles and concaves changed as profiled pairs on condition, exactly as with any modern cone, because chamber geometry economics do not age. The second is treating the spring pack and adjustment components as wear items with a service life, inspected at liner changes rather than after a tramp event exposes them. The wear sets, spring packs and adjustment components in those habits are general catalogue lines — not recorded against the HP sizes, not recorded against the GP series and not recorded against Symons sizes — and our programme supports both habits with a 1-piece minimum order, confirmed with your quotation, and identification by size and part number, including for less common sizes where parts are produced to order and the quotation says so plainly. A classic crusher with a disciplined parts programme is not a legacy burden; it is often the lowest cost-per-tonne machine in the plant.
