Use the standard PXZ models and nominal dimensions to identify spider and liner wear systems, main shafts and protective sleeves, eccentric components, drives and hydraulics, then confirm drawing numbers and request a quotation.
This page covers the models, nominal dimensions, key installation positions, materials and technical checks relevant to spare parts supply. The main shaft and its protective sleeve are shown separately because they are different components.
The two groups of numbers in each model identify the nominal feed opening and cone base diameter series. Manufacturing and quotations still require the project nameplate, full model, serial number, drawing number and general arrangement drawing.

A nominal model designation is not a manufacturing specification. The same model may have different structures or materials across projects, production periods and drawing revisions.
Spider protection, liners, main shaft protective sleeves and shell wear plates are presented in the agreed order of priority. Each card links to the relevant part and material pages.
Spider Cap, Shield & Arm Liner
Located above the feed opening, these parts withstand impact from large rocks, uneven loading and sliding wear. Check the spider arm structure, plate profile, orientation, hole pattern, thickness and feed direction.
Material Selection:Confirm high-manganese steel, quenched and tempered wear plate or a composite wear-resistant construction according to impact energy, plate thickness and fastening method.

Concaves
Installed in segments around the upper shell, concaves form the crushing chamber with the mantle. Check the number of tiers, segment layout, profile, support faces, backing clearance and wear records for each tier.
Material Selection:High-manganese steel is the main candidate. Confirm the grade, chemistry, heat treatment and zoned arrangement according to the ore and impact conditions.

The mantle covers the main shaft cone and moves with its gyratory motion, working against the concaves to crush material. Check the upper and lower profiles, head nut interface, backing and discharge opening.
Material Selection:High-manganese steel is the main candidate. Confirm the material and heat treatment against feed conditions, impact, ore hardness and wear records.

Mainshaft Protective Sleeve
This independent protective component fits around the main shaft; it is not the shaft or shaft assembly. Check the inside and outside diameters, length, locating shoulder, fit and removal direction.
Material Selection:Confirm the base material, surface hardness, heat treatment and fit against the original design. The main shaft material cannot simply be substituted.

Spider Underside Wear Liner
These liners protect the underside of the spider and adjacent areas from flying rock, rebound and abrasive ore flow. Check left/right orientation, plate arrangement and hole patterns.
Material Selection:Select high-manganese steel or quenched and tempered wear plate according to the balance of impact and sliding wear.

Top Shell Wear Plate
These plates protect the upper shell in feed and rebound zones. Check installation zones, plate thickness, curvature, overlaps, fastenings and the boundary with the concave liners.
Material Selection:Confirm quenched and tempered wear plate, high-manganese steel or a composite wear-resistant construction according to impact, abrasion and installation method.
View Part التفاصيل →Identify drive and load-bearing components separately. Check drawing numbers, materials, interfaces and fits individually for the main shaft, external protective sleeve, eccentric bushing, gears, bearings and seals.
Spider Assembly
The complete-machine image identifies the top spider position. For the assembly, check the arms, central support, connecting flanges, lifting points, bushing seats and machine model.
Material Selection:Confirm large cast-steel or welded structures, connectors and support materials against the original drawings, loads and non-destructive testing requirements.
View Part التفاصيل →Mainshaft
The main shaft is a core load-bearing component and must be checked separately from its external protective sleeve. Confirm journals, tapered surfaces, straightness, assembly interfaces and inspection requirements.
Material Selection:Confirm the large forged alloy steel, heat treatment, journal accuracy, straightness and non-destructive testing against the full model and original drawings.

Spider Bearing & Oil Seal
These components support the upper end of the main shaft while maintaining lubrication and sealing. Check shaft diameter, bushing inside and outside diameters, flanges, oil grooves, support structure and seal type.
Material Selection:Confirm bearing copper alloys, steel support components and seal materials according to load, lubrication, temperature and fluid.

View Part التفاصيل →The available public documents do not provide a part-number table traceable item by item to PXZ models, installation positions and drawing revisions. Numbers are therefore not inferred on this page.
Numbering rules:Publish only numbers traceable to a specific model, installation position and original evidence. Record OEM drawing numbers and third-party spare part numbers separately; do not merge or infer them.
No. They identify the machine's nominal series, not manufacturing dimensions for individual parts. Confirm the drawing number, drawing revision, installation position and actual interfaces.
No. The main shaft carries load, while the protective sleeve is a separate component fitted around it. Check dimensions, materials and drawing numbers for each independently.
Start by providing the full model, project nameplate, general arrangement drawing, installation position, used-part photos, drawings and critical dimensions. These allow assessment of identification, reverse measurement, material selection and manufacturing requirements.
Provide the full model, serial number, OEM or third-party number, drawings, used-part photos, material and operating conditions. We use these to identify the part, assess materials, match manufacturing requirements, control quality and deliver finished components.
