ANSI B29.1

Part Number Example:

100TL15.2517ANSI

100 = No. 100 Roller Chain Sprocket (D100 = Double, T100 = Triple)

TL = Taper Lock Type Bushing

15 = 15 Teeth (15H = 15 Hardned Teeth)

2517 = 2517 Taper Lock Bushing

ANSI = ANSI Type Taper Lock Bushing

Note ANSI refers to American Standard Unified Threads used in North America. ANSI Bushings use ANSI 1/2-13 UNC (American) threads. They differ from 1/2 inch BSW (British Standard Whitworth thread) 1/2" x 12tpi BSW used in Europe, and are not interchangeable with 1/2 inch ANSI threads.

Only bushing sizes 2517, 3525 and 3535 use 1/2 inch non-interchangeable ANSI threads.
