Roller Chain Examples

Input Type: Exact Part Number / Designation

User input:

Need replacement options for 10B-1 roller chain.

Captured fields:

Field	Value
identity.selected_part_number	10B-1
identity.selected_designation	10B-1
core_identity.document_reference_standard	ISO_606
core_identity.system_group	B_SERIES
core_identity.designation_base	10B
core_identity.strand_count	1
core_identity.construction_type	ROLLER_CHAIN
attachment.attachment_present	false

How to use it:

• This is a strong identity path.
• 10B is the base chain number; -1 indicates simplex/one strand.
• Do not confuse simplex with system group.

Input Type: Standard + Designation + Attachment

User input:

ANSI 40H-2 roller chain, carbon steel, K1 attachments one side every second pitch.

Captured fields:

Field	Value
identity.selected_designation	40H-2
core_identity.document_reference_standard	ANSI_B29_1
core_identity.system_group	A_SERIES
core_identity.designation_base	40
core_identity.strand_count	2
core_identity.construction_type	ROLLER_CHAIN
query.series_variant	H
query.material_type	CARBON_STEEL
attachment.attachment_present	true
attachment.attachment_signature	`K1

How to use it:

• Attachment presence is decisive; do not compare plain chain as equivalent.
• H is a series variant and must be preserved.
• Strand count 2 means duplex.

Input Type: Dimension-Enriched Chain

User input:

Pitch 12.7 mm, roller diameter 7.92 mm, inner width 7.85 mm, minimum breaking load 27.8 kN.

Captured fields:

Field	Value
dims_mm.pitch_mm	12.7
dims_mm.roller_diameter_mm	7.92
dims_mm.inner_width_mm	7.85
performance.minimum_breaking_load_kn	27.8

How to use it:

• These fields strengthen a non-part-number launch path.
• Pitch alone is never enough.
• minimum_breaking_load_kn drives FB strength checks.

Input Type: Application Constraints

User input:

High-cycle application at 1200 RPM, ANSI sprockets, strict clearance envelope.

Captured fields:

Field	Value
requirements.operating_speed_rpm	1200
requirements.sprocket_standard_required	ANSI_B29_1
requirements.clearance_envelope_strict	true
requirements.application_criticality	HIGH_CYCLE

How to use it:

• These fields constrain candidate suitability.
• Strict clearance and sprocket standard make width/system mismatches more important.
