4A91's DOHC camshafts are driven by a single-stage roller chain of 8.0 mm ( 0.3 in ) pitch and 12.5 mm ( 0.5 in ) width, instead of the previous degrees.

It had two simplex roller chain-driven ( relay method, using three chains ) VR6 engines, leading to cost reduction in one of the most expensive engines Volkswagen Passenger Cars has ever produced.
43.
In other words, conventional roller chain drives suffer the potential for vibration, as the effective radius of action in a chain and sprocket combination constantly changes during revolution ( " Chordal action " ).
44.
The safety bicycle, as it is known today, came into being when the pedals were attached to a crank driving a sprocket that transmitted power to the driven wheel by means of a roller chain.
45.
Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
46.
Modified roller chain has been used extensively in material handling equipment, but could only be used in push-pull applications when a continuous loop of chain was used ( with the exception of chain encapsulated in a guide channel ).
47.
One end of a compensating chain ( typically roller chain ) is suspended from the underside of the counterweight arbor, the opposite end mounted to the adjacent wall, at a point corresponding to half the travel of the arbor.
48.
In the same year, Kyrle Willans suggested that a worn-out conventional locomotive, a Manning-Wardle named " Ancoats ", could be rebuilt with the boiler and engine of a Sentinel steam waggon in the locomotive's frames, connected by a roller chain drive.
49.
The " bushingless " roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose.
50.
Roller chain is ordinarily hooked up using a master link ( also known as a connecting link ), which typically has one pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools.
