COMPONENT REQUIREMENTS

Roll-neck / auxiliary 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

Roll-neck / auxiliary bushing

Roll-neck or auxiliary shaft support with an approved bronze-bushing design.

Provides a specified sleeve-bearing interface around the relevant shaft.

Manufacturing & delivery form
Cast tube or sleeve blank with agreed machining; large-component route requires review.

Roll-neck bearing systems may use rolling elements, composites or other designs. Assess these candidates only where the approved drawing specifies a bronze bushing.

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

Bearing identity: Equipment model, bearing type, shaft position and approved drawing.
Sleeve geometry: Bore, outside diameter, length, grooves and fit requirements.
Shaft & duty: Mating shaft condition, load, speed and operating clearance.
Oil & temperature: Lubrication arrangement, oil supply and actual part temperature.
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; large-component route requires review.

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.
