The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc.
How strong is 50 chain?
General Duty Plus #50H roller chain has a tensile strength of 8,500lbs and is constructed of high quality carbon steel. #50H heavy roller chain is commonly supplied in 10ft boxes but is also available on 50ft reels, 100ft reels, and as custom lengths per request.
What is the advantage of an O-ring chain?
The Key Advantages Of Using An O-Ring Chain O-ring chains have a longer operational life than roller chains, especially under off-road conditions. In some cases, they will last as much as three times longer than a standard roller chain. O-ring chains are virtually maintenance-free after installation.1 Aug 2014
Are O-ring chains quieter?
The O-ring chain will typically be quieter when riding unless your sprockets are worn and/or the chain is out of adjustment.18 Jun 2008
Do O-ring chains rob horsepower?
O-ring chains eat horse power. Over sized chains eat horse power. When you only have 10 - 12 HP to start with, you can't afford to loose any. But if you have a 50 HP bike, loosing half a HP to an O-ring chain isn't noticable.19 Nov 2006
How do I know my chain link size?
- Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line.
- Determine your side plate height and thickness by measuring both inside and outside the roller chain to ensure that you're seeing a good average size.
What are the different sizes of roller chain?
Size Pitch Maximum Roller Diameter
---- ------------------- -----------------------
41 0.500 in (12.70 mm) 0.306 in (7.77 mm)
40 0.500 in (12.70 mm) 0.312 in (7.92 mm)
50 0.625 in (15.88 mm) 0.400 in (10.16 mm)
60 0.750 in (19.05 mm) 0.469 in (11.91 mm)
Is O-ring or non O-ring chain better?
The O-rings encircle the pin bushings, and rest between the outer link and inner link plates. This seals chain grease in the pins and rollers, maintaining better lubrication for longer. Because of this, O-ring chains have a reputation of lasting anywhere from 1.5 2 times longer than standard, non-O-ring chains.9 Jun 2020
What's the difference between an O-ring chain and a non O-ring chain?
The O-ring chain comes with industrial grease sealed in the parts; hence, it lasts longer without needing to be lubricated. The non O ring chains, on the other hand, require regular oiling since all the parts are exposed and there are no rubber rings to help keep the chain oiled for an extended period.
