  • Bottom Bracket Standards and Terminology | Park Tool

    The shell widths range in width from 68mm to 86mm. The cartridge bearings of the PF46 system use an adaptor of plastic or aluminum and are pressed into the bottom bracket shell. Bearing adaptors are made to fit different crank spindle diameters, such as 22/24mm, 24mm, 28.99mm, and 30mm. PF46 bearing adaptor pressing into a PF46 compatible frame

  • 1,1,4,4

    Two small 1,1,4,4-tetracyanobutadiene-functionalized chromophores were obtained by careful leverage of the regioselectivity of the cycloaddition reaction of tetracyanoethylene with anthracene–ynamide derivatives, inducing either a [2 + 2] or a [4 + 2] Diels–Alder process. DFT calculations unraveled the mechanism of the [2 + 2] cycloaddition–retroelectrocyclization reaction sequence with

  • Viscosity Charts

    For example, a lubricant with an ISO grade of 32 has a viscosity within the range of 28.8-35.2, the midpoint of which is 32. Rule of Thumb: The comparable ISO grade of a given product whose viscosity in SUS at 100°F is known can be determined by using the following conversion formula: SUS @ 100°F/5=cSt @ 40°C. cst= 0.226xSUS-(195/SUS)

NOTE: Enveloping and SEE measurements should be taken as close to the bearing load zone as possible. If possible, choose a flat surface to press the sensor tip against.

  • ISO 68 Oil | McMaster

    Formulated to reduce friction and wear, this oil ensures smooth, uniform motion of slides, tracks, and ways. It’s tacky, so it even sticks to vertical surfaces to provide long-lasting lubrication. Viscosity is the thickness of an oil. The higher the grade, the thicker the oil, and the less it flows.

  • ABEC scale

    Lower graded bearings are intended for the vast majority of applications such as vehicles, mechanical hobbies, skates, skateboards, fishing reels and industrial machinery. High ABEC rated bearings allow optimal performance of critical applications requiring very high RPM and smooth operation. ISO's equivalent standard is ISO 492.
