ET single-toggle jaw crushers, EC cone crushers with a moving shaft and EP cone crushers with a fixed shaft. Use standard models and key dimensions to identify jaw plates, chamber liners, shafts, gears, bronze bushings and hydraulic spares.
First identify the ENDURON machine using official standard models and key dimensions, then review wear parts, shafts, drives and hydraulics for its jaw or cone design. Manufacture still requires the nameplate, full model, assembly drawings, used parts, installed interfaces, duty and verified drawing references.
All 14 models in the table have current official Weir data sheets. Capacity figures are official reference ranges and vary with material, chamber, feed, CSS and circuit configuration.

Weir's series pages also state that EC has 4 head sizes, up to 84 inches and 450 kW, while EP has 5 head sizes, 935–1,830 mm and 185–630 kW. Names and dimensions without published model-specific data sheets have not been inferred for this table.
Wear parts are organised by position and chamber design. Material pages support preliminary selection; final grade, chamber, tooth profile, thickness and heat treatment require the full model, material being crushed, CSS, wear pattern and original design.
ET Fixed Jaw Die
Mounted on the front frame to form the stationary crushing face. Check the ET model, tooth profile, thickness, hole positions, orientation, wear allowance and matching moving jaw plate.
Material review: Current Weir literature lists ESCO Production Master II and 14R jaw plates. Confirm the manganese-steel grade, tooth profile and heat treatment against the installed chamber and duty.
View the Component Page →
ET Swing Jaw Die
Mounted on the pitman, it compresses material cyclically through the eccentric mechanism. Check tooth engagement, orientation, clamping wedges and remaining thickness together with the fixed jaw plate.
Material review: Impact resistance and work hardening are the main criteria. Start with high-manganese steels, then confirm the choice against the ore, feed size and original design.
View the Component Page →
ET Cheek Plates & Pitman Protection
Upper and lower cheek plates protect the chamber sides; pitman guards protect exposed areas at the front of the moving jaw. Check each plate's side, level, hole spacing, thickness and fit with adjacent parts.
Material review: Official ET specifications identify manganese steel for cheek plates. Confirm other guard materials according to impact, abrasion and the original design.

EC بطانة المخروط المتحرك / Head Liner
Fitted around the EC moving-shaft and head assembly to form the moving crushing surface. Verify the EC model, standard or short head, chamber, locking arrangement and actual wear profile.
Material review: The official EC series uses ESCO high-performance manganese-steel chambers. Confirm alloy, thickness and chamber profile against the material, CSS and capacity target.

EC بطانة المخروط الثابت / بطانة الوعاء
Fixed inside the bowl, these liners work with the mantle to define the EC chamber and discharge setting. Supply the model, chamber, CSS, feed details and matching mantle when ordering.
Material review: Selection centres on manganese-steel work hardening and chamber matching. Consider liner profile, clamping design and the observed wear distribution alongside material grade.
View the Component Page →EP بطانة المخروط المتحرك & Concave Set
The EP head moves independently around a fixed main shaft. Match mantle and concave as a pair for the EP model, standard or short-head design, and coarse, medium or fine chamber.
Material review: Official EP literature lists ESCO high-performance manganese-steel liners. Before manufacture, verify the chamber, feed, CSS, used-part profile and installed interfaces.
View the Component Page →ET, EC and EP have different main mechanisms; generic labels such as jaw or cone crusher do not establish interchangeability. Confirm the series and model before checking shafts, bushings, bearings, gears, hydraulics and fits.
ET Pitman, Eccentric Shaft & Flywheel
The pitman, forged eccentric shaft, flywheel and pulley form the ET main mechanism. Check shaft diameters, bearing seats, keyways, flywheel orientation and assembly fits for the model.
Material review: Use forged alloy steel as the starting point for the eccentric shaft. Verify pitman and flywheel requirements against the original casting design, non-destructive testing and fit tolerances.
View the Component Page →ET Toggle, Seats & Tensioning System
Toggle plates and seats transmit load and contribute to overload protection; hydraulic wedges and retraction springs control CSS and tension. Verify the complete set of interfaces for the installed version.
Material review: Official literature specifies ductile iron for the toggle plate. Check seats, wedges, tension rods and hydraulic parts according to load, contact surfaces and sealing requirements.

ET محامل أسطوانية ذاتية المحاذاة & Labyrinth الموانع
Large spherical roller bearings in the pitman carry cyclic impact loads, while labyrinth seals exclude dust. Provide the model, bearing designation, journal and housing bore dimensions, and seal design for quotation.
Material review: Verify bearing designation and clearance. Select labyrinth rings, seal materials and lubrication according to dust exposure, temperature and assembly clearances.
View the Component Page →EC Live Shaft, Head & Eccentric
The EC head and main shaft move together within the eccentric mechanism. Verify the EC model, shaft-to-head fit, eccentricity, upper and lower bushings and thrust arrangement.
Material review: Official literature specifies forged alloy steel for the main shaft, cast copper alloy for bushings, and high-strength cast steel for the frame and head.
View the Component Page →
EC Ring Gear, ترس صغير & Hydraulic Adjustment
The pinion drives the eccentric mechanism. Hydraulics adjust and lock the bowl, clear the chamber and provide tramp release. Verify complete assemblies and their interfaces.
Material review: For gears, verify forged alloy steel, tooth heat treatment and meshing accuracy. For hydraulic parts, check pressure, valve assemblies, cylinder bore, seals and pipe connections.
View the Component Page →EP Pedestal Shaft, Bevel Gears & Bushings
EP uses a fixed main shaft and an independently moving head, driven through spiral bevel gears. Verify tooth count, module, spiral hand, bushings and eccentric assembly for the EP model.
Material review: Official literature specifies high-strength forged alloy steel for the fixed main shaft and spiral bevel gears, and cast copper alloy for bushings.
View the Component Page →They cannot be treated as the same cone crusher design. EC has a head and main shaft that move together; EP has a fixed main shaft and an independently moving head. Liners, eccentrics, bushings, gears and hydraulic interfaces must be checked for the series and specific model.
The model narrows the search, but manufacture also requires the nameplate, chamber or tooth profile, drawing reference or used part, key dimensions, orientation, current material and duty. Cone liners also require standard or short-head identification, coarse, medium or fine chamber, and CSS.
Numbers without a traceable OEM catalogue, drawing or installation record are not published. Verified references are assigned to the relevant part position after the full model, drawing reference, used part or reliable installation data is obtained.
Provide the full ET, EC or EP model, nameplate, chamber or tooth profile, drawing reference, used-part photographs, key dimensions, orientation, current material and operating conditions. These support identification, material assessment, manufacturing coordination, quality control and finished-part delivery.
