About ANSI #50 Hollow Pin Roller Chains

CTS® #50 Hollow Pin Roller Chain

CTS® ANSI #50HP hollow pin roller chain is a 5/8" (15.875 mm) pitch roller chain in which the standard solid pins are replaced by hollow, through-bored pins. The 5.13 mm pin bore accepts cross rods, cotter pins, slats, trays, and custom attachments, so the chain can both drive a system and carry products at the same time. As with every chain CTS builds, the #50HP is produced to ANSI/ASME B29.1 dimensional and strength requirements for full interchangeability with standard #50 sprockets.

For a quotation or other information on hollow pin roller chains, please contact us, and we will be happy to help you.

Quality Assurance:

ANSI #50 Hollow Pin Roller Chain Technical Data

An ANSI #50 hollow pin chain uses the same 15.875 mm pitch, 10.16 mm roller diameter, and 9.40 mm inner width as a standard ANSI #50 roller chain, but each pin is drilled through with a 5.13 mm bore. Cross rods or attachments are passed through the pins and fixed with cotter pins or circlips, converting a drive chain into a conveying chain.

#50 Hollow Pin Roller Chain Dimensions

Pitch(P): 15.875 mm
Roller diameter(d1): 10.16 mm
Width between inner plates(b1): 9.40 mm
Pin diameter(d2): 7.03 mm
Pin diameter(d3): 5.13 mm
Pin length(L): 20.7 mm
Pin length(Lc): 21.9 mm
Inner plate depth(h2): 15.09 mm
Plate thickness(T): 2.03 mm
Tensile strength: 20.0/4545 kN/lbf
Weight per meter: 0.91 kg/m

Typical uses include product transfer where a solid surface is not practical: oven bands, cooling tunnels, bottle and can handling, box transfer at right angles, and gravity or scraped conveyors. Because the pin is hollow, tensile strength is lower than that of a solid-pin chain of the same size (20.0 kN / 4545 lbf for #50HP), so hollow pin chains are specified for conveying duty rather than high-torque drive duty.

Hollow Pin vs. Solid Pin: Which One Fits Your Application?

Item	ANSI #50HP Roller Chain	ANSI #50 Standard Roller Chain
Pin Bore	5.13 mm through bore, accepts cross rods	None
Chain Attachments	Cross rods, slats, trays, pushers, flights - no special attachment links needed	Requires ANSI attachment chain (A1/K1 types)
Tensile Strength	20.0 kN /4545 lbf	Approx. 21.8 kN / 4900 lbf
Best For	Conveying, product carrying, light drive + transport combined	Power transmission, high-load drive, shock loads
Miantenance	Check cross rods and cotter pins as well as chain elongation	Check elongation and lubrication only
