NavePart of a wheel: connects the rim to wheel hub. | |
NavigationThe way in which you get around a program or website. | |
NDSNeutral Drive Switch. | |
Needle BearingA bearing made from small diameter rollers in between inner and outer bearing tracks. | |
Negative CamberSteering geometry where the road wheel leans inward at the top. | |
Negative CastorAngle in side elevation between the steering and vertical axis. Steering axis hits the ground behind the vertical axis. | |
Negative CommunicationA comment or statement expressing lack of approval. | |
Negative Offset (Wheel)The position of the wheel nave or disc when inside the centre line of the wheel. | |
Negative ScrubNegative scrub radius steering geometry where a line through the steering swivel axis meets the road surface outside of the tyre centre line. | |
Negative Temperature CoeffcientSee Negative Temperature Coefficient. | |
Negative Temperature CoefficientType of resistor that has resistance reducing with increases in temperature. These resistors are used in electrical circuits to give temperature sensing and control. Thermistor. | |
Negative Temperature CoeficientSee Negative Temperature Coefficient. | |
NetworkInterlinked group of computers so that resources can be shared. | |
Network CardA piece of hardware that allows computers to be connected to a network. | |
NeutralGearbox position when no gear is selected and no drive transmitted. | |
Neutral Drive SwitchOn a transmission system, a switch that makes when neutral is selected. | |
Neutral SteerSteering condition when the vehicle follows a true line in relation to the steered wheels. | |
NeutronOne of a number of particles in the nucleus of an atom. The neutron has no polarity and is electrically neutral. | |
New and like-new finishesFinishes that have maintained a brilliant, high-gloss performance. | |
Newton (N)A standard unit of force. | |
Ni(OH)2Nickel di-hydroxide | |

NiOOHNickel hydroxide | |
Nip (Bearing)The amount by which shell bearing halves are clamped in order to secure them in their housing. | |
NmNewton Metres | |
Non IndependentDescribes suspension systems using a solid beam axle where the movement of one wheel affects the other wheel on the same axle. | |
Non-ferrousDescribes metals which contain no iron. | |
Non-metallicUsed to describe paint finishes that do not contain metallic pigments, i.e. Solid colours | |
Non-porousPrevents flow or holds back a liquid. | |
