Axial load - ✔✔An external load that acts lengthwise along a
shaft.
Belt Whip - ✔✔A condition where excess slack in a drive belt
causes it to begin riding up and out of the sheave grooves,
primarily on the slack side. The slack side is the side of the belt
that exits the drive pulley as it rotates.
Borescope - ✔✔An optical device that typically uses fiber optics to
display an image through a narrow tube, allowing for the

lubricants resistance to flow, identifying the relationship between
simple viscosity and the density of the lubricant.
Dispersants - ✔✔In lubricants, an additive used to disperse or
disband groups of particles to prevent them from coagulating or
joining together.
Dropping point - ✔✔The temperature at which grease is soft
enough for a drop of oil to fall away or flow from the bulk of the
grease.
Dynamic seal - ✔✔A seal made where there is movement
between two mating parts, or movement between one of the parts
and the seal.
Fire point - ✔✔The temperature at which oil will burn if ignited.
Flash point - ✔✔The temperature at which oil gives off ignitable
vapors.
