Use 9 standard models to identify blow bars, apron and frame liners, rotors, bearings, hydraulics, materials and specialist maintenance tools.
This page focuses on installed models, key dimensions, wear materials, load-bearing and adjustment spares, and maintenance tools relevant to supply. Manufacturing and quotation require the full model, serial number, drawing reference and drawing.
Feed opening, power, recommended maximum feed and machine weight support identification. Interchangeability still requires serial number, rotor configuration and part-reference checks.

Feed Liner
Withstand large-feed impact and sliding. Check drop height, maximum feed, support and fastening. The image identifies the category; confirm full NP model, serial number, drawing, profile and interface dimensions.
View the General Component Page →Verify general spares by load, fits, lubrication and interfaces. Cards link to component pages; use this OEM page to check installed model and serial number.
Rotor Assembly
The load-bearing core of the rotor, shaft and bar system. Check diameter, width, bar configuration, balance grade and shaft interfaces. The image identifies the category; confirm full NP model, serial number, drawing, profile and interface dimensions.
View the General Component Page →
Rotor Shaft
Carries combined bending, torsion and impact. Check forging, heat treatment, journals, fillets, nondestructive testing and balance. The image identifies the category; confirm full NP model, serial number, drawing, profile and interface dimensions.
View the General Component Page →
Rotor Bearing
Support the high-speed, heavily loaded rotor. Selection depends on load, speed, clearance, lubrication, temperature rise and housing fit. The image identifies the category; confirm full NP model, serial number, drawing, profile and interface dimensions.
View the General Component Page →
Bearing Housing
Locate bearings, transfer loads and support sealing. Check holes, centre height, fits, lubrication and frame interfaces. The image identifies the category; confirm full NP model, serial number, drawing, profile and interface dimensions.
