Start with six standard models and key dimensions to identify fixed and swing jaw plates, cheek plates, eccentric shafts, bearings, toggle plates, tensioning, adjustment and seal spares, then confirm materials and drawing for an enquiry.
EB and EB Pro are single-toggle jaw crushers. This page covers the standard models, dimensions, installation positions, material selection, drawing checks and enquiry information directly needed for spare identification.
Capacity, feed opening, CSS, speed, drive power, equipment weight and overall dimensions come from the corresponding official FLS datasheets.

Start with fixed and swing jaw plates, followed by upper/lower cheek plates, intermediate plates, feed guides and structural protection plates. Each item links to its part and material pages.
Fixed Jaw Plate
Fixed jaw plates attach inside the front wall and form the chamber with the swing jaw plates. Check model, one-piece/segmented construction, tooth profile, top/bottom direction, thickness, hole pattern, clamping method, CSS and used-part wear profile.
View Part Details →
Movable / Swing Jaw Plate
Mounted on the swing jaw body, these are the main wear surfaces under cyclic load. Check tooth profile, relative tooth peak positions, plate width, top/bottom location, clamping wedges and pairing with the fixed jaw plates.
View Part Details →
Upper Cheek Plate
These protect the upper chamber sides. Check left/right side, shape, thickness, hole pattern, feed opening profile, jaw plate clearance and adjacent guard overlaps.
View Part Details →
Lower Cheek Plate
These protect lower sidewalls near the discharge opening. Check left/right side, thickness, hole pattern, CSS adjustment range, working clearance at jaw plate ends and discharge path.
View Part Details →
Intermediate Plate
These protect transition areas around jaw plates or the body. Check the specific model, installation layer, plate shape, thickness, hole pattern, contact faces and relationships with adjacent jaw plates or guards.
View Part Details →Deflector Plate
These guide feed and protect upper body impact zones. Check drop direction, thickness, angle, hole pattern, supports and safe clearance to flywheels/guards.
View Part Details →
Pitman and Front Casting Protection Plate
These shield the swing jaw body or front wall from direct wear. Check protection zone, installation side, overall shape, hole pattern, thickness, pads and overlap with the main jaw plates.
View Part Details →Parts with the same name are not interchangeable by appearance across EB models, sides or generations. Check drawing, fits, dimensional relationships, materials and function.
Eccentric Shaft
The shaft drives reciprocating swing jaw movement. Check eccentricity, journals, overall length, flywheel/pulley end, keyways, threads, bearing fits, rotation direction and dynamic balance requirements.
View Part Details →
Spherical Roller Bearing
These support the eccentric shaft and swing jaw under radial impact and assembly misalignment. Check bearing model, clearance, shaft/housing fits, locating end, adapter sleeve, seals, lubrication and temperature rise.
View Part Details →
Toggle Plate
These connect the swing jaw to the rear support, transmitting crushing force and contributing to overload protection. Check length, width, thickness, both end profiles, installation direction, CSS range and mating toggle seats.
View Part Details →Toggle Seat
These support toggle plate ends and provide oscillating contact surfaces. Check front/rear seat, length, curvature, groove profile, installation direction, contact pattern and pairing with the toggle plate.
View Part Details →
Tension Rod
Together with the spring system, these maintain the working relationship of the toggle plate and swing jaw mechanism. Check overall length, diameter, thread, end geometry, preload position, installation direction and matching springs.
View Part Details →
Tension Spring
These work with tension rods to maintain mechanism preload. Check outside diameter, wire diameter, free length, active coils, winding direction, end type and working compression.
View Part Details →
CSS Adjustment Wedge
These provide mechanical or hydraulically assisted discharge setting adjustment. Check left/right and upper/lower position, taper, length, thickness, hole pattern, contact faces and actual CSS adjustment range.
View Part Details →
Jaw Die Clamping Wedge
These secure fixed or swing jaw plates. Check upper/lower wedge, installation side, taper, hole pattern, threads, clamping face and jaw plate edge profile.
View Part Details →
Labyrinth Dust Seal
These protect eccentric shaft bearings and lubrication areas. Check seal diameter, labyrinth stages, axial clearance, fastening method, lubrication passages, rotation direction and adjacent guards.
