COMPONENT REQUIREMENTS

Main shaft bushing

Define the geometry, material, delivery condition and acceptance criteria for the selected application. Manufacturing scope requires review of the approved drawing and operating requirements.

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.
