COMPONENT GUIDE

Worm wheel blank

Bronze worm-wheel position in a reducer or low-speed drive.

Provides the blank from which a specified worm wheel is machined.

Manufacturing & delivery form
Cast solid or ring blank with agreed premachining; tooth cutting specified separately.

A blank is separate from a finished worm wheel. Tooth accuracy and life require the complete drive and finishing specification.

Material candidates

UNS C90700 Tin bronze

Candidate for gear and worm-wheel blanks.

Confirm the mating gear, lubrication and machining scope. An alloy designation does not establish finished gear accuracy.

UNS C90500 Tin bronze

Candidate for drawing-defined gear blanks and selected lubricated components.

Confirm the governing standard, casting form and duty. C90500 and C90700 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

Blank structure: Hub/rim configuration, outside diameter, bore, web and drawing revision.
Machining plan: Datums, stock allowance, tooth-cutting responsibility and final acceptance.
Mating worm: Worm drawing, material, interface and specified alignment.
Drive conditions: Load, speed, lubricant and required hardness condition.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Cast solid or ring blank with agreed premachining; tooth cutting specified separately.

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

Drive nut blank

Lead-screw drive or adjustment mechanism specified with a bronze nut.

Provides a blank for the nut body and agreed thread-machining scope.

Manufacturing & delivery form
Nut casting blank with agreed machining; suitable stock may be considered for small geometry.

The steel screw is a separate component. Nut material alone does not establish precision positioning performance.

Material candidates

UNS C90500 Tin bronze

Candidate for drawing-defined gear blanks and selected lubricated components.

Confirm the governing standard, casting form and duty. C90500 and C90700 are distinct grades.

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

Nut & thread: Body envelope, thread designation, engagement and mating-screw drawing.
Machining scope: Thread responsibility, stock allowance, bore axis and datums.
Movement & load: Axial load, reciprocating speed, cycle and specified backlash.
Contact conditions: Screw material, lubrication and actual operating temperature.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Nut casting blank with agreed machining; suitable stock may be considered for small geometry.

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

Plain bearing bushing

Drawing-defined sliding support in machine tools, textile or general machinery.

Supports relative shaft movement through a specified sleeve-bearing surface.

Manufacturing & delivery form
Cast sleeve blank or tube stock with agreed bearing-surface machining.

A plain bushing is distinct from a rolling bearing. C93200 does not imply permission for dry running.

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 C90500 Tin bronze

Candidate for drawing-defined gear blanks and selected lubricated components.

Confirm the governing standard, casting form and duty. C90500 and C90700 are distinct grades.

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

Bushing geometry: Bore, outside diameter, length, shoulders and groove layout.
Fit & finish: Shaft/housing fit, running clearance and bearing-surface finish.
Mating shaft: Shaft material, hardness, roughness and condition.
Bearing duty: Contact load, sliding speed, lubricant and temperature.
Material & acceptance: Specified alloy and standard, supply condition, drawing revision, quantity, inspection criteria and required records.
Supply form: Cast sleeve blank or tube stock with agreed bearing-surface 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.
