COMPONENT GUIDE

Eccentric bushing

Sliding interface within the crusher eccentric assembly.

Forms the specified sliding bearing interface around an eccentric component.

Manufacturing & delivery form
Specified sleeve casting blank with rough or finish machining agreed per drawing.

Identify inner or outer eccentric bushing separately. Material substitution cannot correct an unresolved lubrication or clearance problem.

Material candidates

UNS C93200 Leaded tin bronze

Candidate for lubricated bushings, bearings and thrust interfaces.

Contains lead. Confirm load, speed, shaft condition and lubrication; no dry-running capability is implied.

UNS C93700 High-leaded tin bronze

Candidate for specified lubricated bearing interfaces.

Contains lead. Higher lead content does not establish a suitable load capacity; confirm the equipment specification.

UNS C95400 Aluminium bronze

Candidate for drawing-defined loaded sliding and wear components.

Review mating material, lubrication and supply condition. C95400 and C95800 are distinct grades.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Eccentric geometry: Part number, inner/outer position, diameters, offsets and machining datums.
Fits: Roundness, running clearance at the specified condition and mating shaft dimensions.
Oil circuit: Grooves, oil passages, lubricant, oil temperature and supply conditions.
Condition record: Wear or burnout location, shaft damage and relevant operating history.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Specified sleeve casting blank with rough or finish machining agreed per drawing.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.

COMPONENT GUIDE

Main shaft bushing

Drawing-defined sliding support around the crusher main shaft.

Provides a replaceable bearing surface at the specified main-shaft interface.

Manufacturing & delivery form
Cast sleeve blank with machining scope agreed per component.

The bushing is separate from the steel main shaft. Identify main-shaft and head-bushing terminology from the approved drawing.

Material candidates

UNS C93200 Leaded tin bronze

Candidate for lubricated bushings, bearings and thrust interfaces.

Contains lead. Confirm load, speed, shaft condition and lubrication; no dry-running capability is implied.

UNS C93700 High-leaded tin bronze

Candidate for specified lubricated bearing interfaces.

Contains lead. Higher lead content does not establish a suitable load capacity; confirm the equipment specification.

OEM-specified grade Aluminium bronze family

A material-family candidate for an approved crusher-bushing design.

Specify the exact alloy and governing standard from the approved equipment drawing; a family name alone is insufficient.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Part identity: Crusher model, approved drawing and installation location.
Concentric features: Bore, outside diameter, length, coaxiality and roundness requirements.
Mating shaft: Shaft material, hardness, surface finish and running clearance.
Bearing conditions: Load, shaft movement, oil supply and groove arrangement.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Cast sleeve blank with machining scope agreed per component.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.

COMPONENT GUIDE

Thrust washer / thrust ring

Local axial support and clearance-control interface.

Provides a drawing-defined axial contact or replaceable wear face.

Manufacturing & delivery form
Cast ring blank or machining from suitable stock; route to be agreed.

A washer or ring is a component of the arrangement, not a complete thrust bearing.

Material candidates

UNS C93200 Leaded tin bronze

Candidate for lubricated bushings, bearings and thrust interfaces.

Contains lead. Confirm load, speed, shaft condition and lubrication; no dry-running capability is implied.

UNS C95400 Aluminium bronze

Candidate for drawing-defined loaded sliding and wear components.

Review mating material, lubrication and supply condition. C95400 and C95800 are distinct grades.

UNS C86300 Manganese brass / manganese bronze

Candidate for specified heavily loaded sliding parts and nut blanks.

A high-strength brass family, not tin bronze. Confirm the counterface and lubrication; no universal wear-life claim applies.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Ring geometry: Inside/outside diameters, thickness, steps and locating details.
Contact faces: Flatness, parallelism, finish and mating materials.
Axial duty: Axial load, relative sliding speed and alignment conditions.
Lubrication: Oil holes, grooves, lubricant and operating temperature.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Cast ring blank or machining from suitable stock; route to be agreed.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.

COMPONENT GUIDE

Countershaft bushing

Countershaft or pinion-shaft support in a specified crusher.

Supports the rotating countershaft through the specified sliding interface.

Manufacturing & delivery form
Cast tube or sleeve blank with agreed machining.

The bronze bushing is separate from the countershaft. Confirm both the shaft interfaces and the model-specific bearing arrangement.

Material candidates

UNS C93200 Leaded tin bronze

Candidate for lubricated bushings, bearings and thrust interfaces.

Contains lead. Confirm load, speed, shaft condition and lubrication; no dry-running capability is implied.

UNS C93700 High-leaded tin bronze

Candidate for specified lubricated bearing interfaces.

Contains lead. Higher lead content does not establish a suitable load capacity; confirm the equipment specification.

Confirm the drawing, actual duty, material standard and manufacturing condition. Material substitutions require customer approval, and supply scope is agreed after component review.

Component RFQ requirements

Bushing geometry: Bore, outside diameter, length, shoulders and oil-groove positions.
Shaft interface: Shaft hardness, finish, housing fit and operating clearance.
Rotating duty: Shaft speed, load direction and operating temperature.
Lubrication: Lubricant, feed holes, grooves and contamination conditions.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Cast tube or sleeve blank with agreed machining.

Start with your drawing, specified alloy and quantity. Include the required delivery condition and acceptance records so the manufacturing and inspection scope can be reviewed.
