Roller Chain Type

AS35 Side View

ANSI Stainless Steel Roller Chain The old standard stainless steel roller chain. Wharton Associates uses the best available chain with hardened pins and bushing for better wear. Links are 3/8" and product must be a multiple of 3/8" unless using half-pitch pinchers which give 3/16" resolution.

RF06B Side View

Metric or TECO Chain An ISO standard chain introduced by a linking machine manufacturer. It is much more expensive and requires different gears on the twisting head. The pitch of the roller chain is still 3/8".

Pitch

The length of the product determines the Pitch. The Pitch is the distance between the pinchers. Each Pitch is .375 inches. For example, a 16 Pitch chain is 6.00 inches between each pincher.

Series

The Series of a chain is determined by the type of lug that´s used. Casing size determines the lug type. Listed below are the casing ranges for each lug type.

Standard Lug Large Lug

Lug Types Lug Type Townsend Equiv. Casing Sizes Large lugs 02121 or D5023-3 24 to 36 Standard lugs 02158 or D5023-2 19 to 27 Cocktail lugs 05924 or D5023-1 15 to 21

Cocktail Lug

Pinchers

The Pincher is determined by which lug type is used. Standard and large lugs use the S/L Pincher. Cocktail lugs use the Cocktail Pincher. Half Pitch chains use the Half Pitch Pincher. This allows for 3/16" spacing of the Pinchers rather than the 3/8" fill pitch spacing.

SL Pincher

S/L Pincher The S/L Pincher is used with Standard and Large lugs.

Half Pitch Pincher

Half-Pitch Pincher An offset pincher that allows 3/16" resolution of the product length (other pinchers are 3/8" resolution). Chains must have an even number of cells.

Cocktail Pincher

Cocktail Pincher The Cocktail Pincher is used with Cocktail lugs. The pincher valley is 1/16" higher for use with #21 and smaller casings.
