Start with CG810i, CG820i, CG830i and CG850i models to identify spider and liner systems, mainshafts, bushings, drive and hydraulic parts, then confirm drawings and request a quotation.
This page covers official specifications, key installation positions, material checks, drawing identification and enquiries relevant to spare-part supply. Model cards use the current short names on the manufacturer's website; the technical table retains CG800i designations.
Weights, feed openings, capacities and power ratings below come from Sandvik's current official CG800i specification table. Confirm the installed machine using its nameplate, serial number, chamber configuration and equipment documents.
| Model | Machine weight | Feed opening | Capacity | Motor power |
|---|---|---|---|---|
| CG810i | 128 t | 1,067 mm | 1,300–2,700 t/h | 315 kW |
| CG820i | 244 t | 1,372 mm | 1,500–4,000 t/h | 525 kW |
| CG830i | 380 t | 1,525 mm | 2,700–6,000 t/h | 660 kW |
| CG850i | 500 t | 1,549 mm | 3,800–8,250 t/h | 950 kW |
The numbers on the diagram correspond one to one with the rows below.
| No. | Component | Location | Applies to |
|---|---|---|---|
| 1 | Concave segments | Tiered crushing faces inside the left shell | CG800i OEM family section (dimensions not specified) |
| 2 | Mantle | Crushing cone around the central shaft | CG800i OEM family section (dimensions not specified) |
| 3 | Main shaft | Central vertical shaft in the right-hand original view | CG800i OEM family section (dimensions not specified) |
| 4 | Countershaft | Lower horizontal drive shaft on the right | CG800i OEM family section (dimensions not specified) |
Spider protection, concaves, mantles and mainshaft sleeves are shown first. Each card identifies the installation position, service conditions and material checks, with a link to the shared component page.
Spider Cap, Shield & Arm Liner
Above the feed opening, these parts face direct impact from large rocks, uneven loading and sliding wear. Check spider geometry, arm count, plate profile, hole pattern, thickness and feed direction.
View the common part page →
Concaves
Segments line the upper shell and form the chamber with the mantle. Check chamber type, tiers, segmentation, support rings, backing clearance and wear profile at each tier.
View the common part page →Mantle
The mantle covers the mainshaft head and moves with the gyrating shaft to crush against the concaves. Check upper and lower profiles, head-nut interface, backing, discharge setting and wear zones.
View the common part page →
Mainshaft Protective Sleeve
Mounted around the mainshaft to protect its working surface. This separate component is neither the mainshaft nor the mainshaft assembly. Check bore, outside diameter, length, locating shoulders and fits.
View the common part page →
Spider Underside Wear Liner
Protect the spider underside and adjacent areas against rock impact, rebound and abrasive flow. Check left/right orientation, plate layout, holes and contact surfaces against the spider.
View the common part page →
Top Shell Wear Plate
Protect feed and rebound zones in the upper shell. Check installation zones, thickness, curvature, overlaps, fastening and boundaries with the concaves.
View the common part page →Identify the mainshaft separately from its protective sleeve. Check drive, load-bearing, bearing and hydraulic sealing parts by series, full model, serial number, drawing revision and mating dimensions.
Spider Assembly
The machine image locates the upper spider. For the assembly, check arm structure, central support, connecting flanges, lifting points, bushing seat and machine model.
View the common part page →
Mainshaft
The machine image indicates the mainshaft centreline; it is not a photograph of the separate shaft. This critical load-bearing component must be checked separately from its external protective sleeve.
View the common part page →
Spider Bearing & Oil Seal
Support the upper mainshaft while retaining lubrication and sealing. Check spherical support geometry, shaft diameter, bushing bore and outside diameter, flange, oil grooves and seal type.
View the common part page →
Eccentric Bushing
Located within the eccentric mechanism to generate and support mainshaft gyration. Check eccentricity, bore and outside diameter, top/bottom orientation, oil grooves, shoulders and running clearance.
View the common part page →
Bevel Gear
The image identifies the bevel-gear drive category. Check the gear and pinion as a pair for module, tooth count, pressure angle, spiral direction, mounting distance and contact pattern.
View the common part page →
Pinion
Works with the bevel gear to transmit horizontal-shaft power. Check tooth count, spiral direction, tooth geometry, shaft interface, backlash and paired mesh records.
View the common part page →
Pinionshaft Bearings
Support the horizontal pinionshaft and maintain gear centre distance. Check bearing designation, clearance, load direction, journal and housing tolerances and lubrication.
View the common part page →
Pinionshaft Seals
Keep dust out and lubricant in the drive housing. Check shaft diameter, grooves, lip direction, temperature, oil, speed and end-cover geometry.
View the common part page →
Hydroset Bushings
Used in the hydraulic adjustment and mainshaft support system. Check upper/lower position, diameters, axial height, oil grooves, fitting clearance and hydraulic interfaces.
View the common part page →
Hydroset Piston Seal
Retains hydraulic adjustment pressure and excludes contamination. Check cylinder and rod diameters, grooves, pressure, temperature, fluid and seal-stack orientation.
View the common part page →
Dust Sealing System
Protects eccentric and lubrication areas. Check sealing rings, grooves, contact faces, purge or overpressure conditions and associated dust-ring geometry.
View the common part page →
Step Bearing Components
Carry mainshaft axial loads in conjunction with the hydraulic adjustment system. Check stacking order, contact diameters, oil-film clearance, thrust faces and assembly height.
View the common part page →Sandvik's current product cards use CG810, CG820, CG830 and CG850; official technical tables and brochures use CG810i, CG820i, CG830i and CG850i. Enquiries should use the full nameplate designation and serial number.
No. The mainshaft is a critical load-bearing component; the sleeve is a separate protective part fitted around it. Check drawing, dimensions and materials separately.
Part numbers must be traceable to the model, installation position and drawing revision. Without reliable evidence, inferred numbers are not published. Send us a drawing or sample and tell us the equipment model and part name.
Provide the full model, serial number, drawings or samples, used-part photos, material and operating conditions. These support part identification, material assessment, manufacturing matching, quality control and finished-part delivery.
