Finish Line Teflon Synthetic Grease

Product Information

History [ edit ] Advertisement of the Happy Pan, a Teflon-coated pan from the 1960s Advertisement for Zepel, the trade name used to market Teflon as a fabric treatment PTFE thermal cover showing impact craters, from NASA's Ultra Heavy Cosmic Ray Experiment (UHCRE) on the Long Duration Exposure Facility (LDEF) Logo of Teflon, the commonly known brand name of PTFE-based compositions manufactured by Chemours Another important thing is the speed. When a bicycle is ridden around 30 km/h, wheels turn about 250 times per minute (250 rpm). Pedals are rarely turning faster than 100 revolutions per minute, while the steerer bearings rpm is much lower. Also, the distances traveled by bearing balls are relatively small due to the small diameter shaft. When the tyre travels around one meter, hub bearings cover a distance of under 10 centimeters.

Bottom line, for reasons noted in this reply, as well as in the post, NLGI 2 is “the sweet spot” of grease consistency in my opinion and experience. Those who think differently can choose for themselves. Since you mention science all the time (though this goes under engeneering IMO), I’m open to any comparative tests and results. My data comes from primitive non-scientific experience of hundreds of serviced bearings and seeing how they fare after a year (or two-three for “lazy” customers) has passed, as well as lots of books read and experts consulted. And I’ll repeat – if you see any errors, bad info, please correct – I’m grateful for any imput to improve the data.Consistency (hardness) is measured with a cone, by methods standardized underASTM 217 IP 50, or DIN 51804, part 1. Measuring unit represents depth the measuring cone enters the tested grease. Testing procedure is shown in the picture 1. Picture 2 Similar arguments (or “arguments”) as Reason. Complete misunderstanding of the whole post (and subject), trying to find something to criticize. Don’t know why. Why do trolls troll? 🙂

Serbia is technically in Central Europe, but we’ve had a fair share of “engine revitalization/protection” additives and “super lubes”, “special Russian military lubricants” etc. 🙂 For coaster brake hubs (hub brakes) – good choice are greases that can withstand high temperatures (generated when braking). Lithium-complex soap based greases, or (if not sparing money, or they are already at hand) – lithium complex with molybdenum disulfide (MoS 2).Solid lubricant is a material used as a dust, or a thin film layer, to protect adjacent sliding surfaces and reduce wear and friction during their relative movement. In practice, solid lubricants are often suspended in oils, or added to greases (see 3.2.3. special greases). you wrote something above. That nlgi 1 doesn’t hold bearings well enough. Are you referring to loose bearings? because in newer years there are no loose bearings anymore and the cage their in hold themin place. In addition to that, I haven’t noticed any problems with using NLGI 2 grease. Lubrication, water washout resistance, even drag – none. On the other hand: price, availability and convenience (if servicing loose ball bearings) – all go in favor of NLGI 2, at least in my region. Bicycle bearings, whether on wheels, cranks, or fork, are usually ball bearings, i.e. they consist of balls, trapped between two races. These bearings are almost never made to be easily re-lubricated from the outside, without disassembling them, so frequent lubrication would take a lot of time.

The brand name Zepel was used for promoting its stain-resistance and water-resistance when applied to fabrics. [12] Sorry but basing it purely on base oil composition isn’t the issue there. You can have a huge variance of working temperatures based on what the grease is made for. It’s not like all lithium greases are within X and Y working temperatures – far from it. “I do not understanding all technical terms but in Wikipedia it is explained simply as treatment forming a protective cermet or ceramic-metal coating on the friction metal parts of the mechanisms directly during the process of their operation: https://en.wikipedia.org/wiki/Revitalizant

Criterion 5 – Keeping stable structure and hardness for a longer period of exploitation. Re-lubing bicycle bearings more often than once a year is highly impractical. First. Some days ago I bщгпре a calcium grease Motul Nautic Grease. It has temperature range from -30 C to +120 C. Also I have bicycle lithium TF2 Grease with temp. range from -20 C to +120 C. In this case calcium grease has better temperature range than lithium grease. But in article “These greases have a relatively narrow working temperature range. I.e. if bicycle is ridden below -20 °C, or it stays in hot summer sun before riding (over +35 °C), then they are not the best choice”. I ride in any temperature range (-30 – +35) and in any weather conditions. Also salt protection is very matter for me becouse salt applied to roads to protect against ice. So is my choose enough good and calcium grease have better temp. range than lithium grease? NLGI1 does not leak out of bearings faster especially with many of these are sealed bearings with covers. Please support WITH DATA.”My main “objections” to aluminium and polyurea greases are price and compatibility. Put plainly: for traffic safety, “the best” option is a tank, while an optimal recommendation most people would be well served with is just a plain old Volvo car. High temperature greases– for working temperatures that in a prolonged period of time stay above +100 °C (often even +200, or over +300 °Cin some cases). You are trying very hard to find objections, but I don’t understand why. I’ll reply to each, one by one. One more time. 🙂 Having used scores of lubes over fifty years, I still fall for the hype now and then. Random observations: First major bike rebuild, circa 1965, saw me using some ancient Texaco canned pumpkin-colored grease my father had forever. It was sort of NGLI 1.5-2, smelled strong, and worked – yet, upon the next overhaul a year or two later, found rusty bearings still coated in brown wet grease.
