Wear parts
Wear Parts and Liner Systems
Identify impact, compression and sliding abrasion by position before selecting material, heat treatment, chamber profile, segments and fasteners.
02
Mantle Liners
Mantle
Cover the head and form the chamber with concaves. Select material and profile by chamber, closed-side setting, material and wear distribution. Image shows installation position.
03
Spider Arm Guards
Spider Arm Shields
Protect spider arms and upper feed areas from direct large-rock impact. Prioritize toughness, fit and reliable fastening. Image identifies the category.
04
Spider Underside Liners
Spider Underside Wear Liners
Under the spider and above the chamber, these resist rebound and erosion. Distinguish impact from sliding zones by position. Image identifies the category.
05
Upper Shell Wear Plates
Top Shell Wear Plates
Protect upper-shell internal and secondary surfaces. Select cast wear parts, quenched-and-tempered plate or composites by impact/abrasion balance. Image identifies the category.
06
Pinion-Shaft Arm Liners
Pinionshaft Arm Liners
Protect the shell around the drive-shaft arm from falling-feed impact and fines abrasion. Check holes, profile, thickness and replacement space. Image identifies the category.
Spare parts
Drive and Core Spares
Identify spider, main shaft, protective sleeve and spider bushing separately. Check eccentric, gears, bearings and hydraulics together with adjacent assemblies.
01
Spider and Spider Assembly
Spider / Spider Assembly
Spans the feed opening and guides the shaft's upper end. Distinguish spider body, cap, guards, bushing, seals and connections in the enquiry.
View the General Component Page →02
Main Shaft
Main Shaft
A separate forged-steel load-bearing part supporting the head and transmitting gyratory loads. Check journals, tapers, threads, material, heat treatment and nondestructive testing.
View the General Component Page →
03
Main Shaft Protective Sleeve
Mainshaft Protective Sleeve
A separate protective part around the shaft, distinct from the shaft itself and quoted separately from the assembly. Check fitting sections, interference and surface requirements.
View the General Component Page →04
Spider Bushing (Tapered Bushing)
Spider Bushing
At the spider centre, it guides the shaft's upper end. Official construction literature identifies a manganese-bronze bushing for MKIII. Check material, clearance, oil grooves and concentricity together.

6275UG OptiShell™ Rotation System
6275UG literature lists optional OptiShell™ for rotating the upper shell and spider. Confirm applicability to an existing machine by configuration and official interfaces.
FAQ
Frequently asked questions
What machine information is needed for a quotation?
Full model, serial number, assembly/part reference, latest drawing, current-part photographs, material, key dimensions, processed material and failure details.
Are the main shaft and protective sleeve the same part?
No. The shaft is the internal load-bearing forging; the sleeve is a separate outer protection part. Identify, measure and quote them separately.
Is 42-65 or 60-89 enough for manufacturing?
The model only narrows the scope. Liners need chamber verification; gears and bushings also require drawing, tooth system, fits, material, serial number and revision.
