Mounting Sensor Magnets with Tolerance Rings
range allows for the differences in thermal expansion, countering the long term effects of creep and cold flow with softer plastic housing materials. Assembly is always important with any mounting method. We already discussed the advantages of being able to make adjustments with the use of a Tolerance

How Rings Work
and stabilizes. The ring now conforms to the mating components and some slight plastic set has occurred. At this point the resultant spring rate can be determined. Typical Compression Ranges in Different Applications: Bearing Mount - 0-9% could go higher to accommodate greater thermal affects. Torque

Everything you wanted to know about seals, almost
and fitting seals, metal gaskets, and V-seals. Gask-o-seal molds an elastomer directly into grooves of metal or plastic retainers. A special section covers a range of unusual design considerations, such as contact with acids and bases, fuels, high pressure, medical, and temperature considerations. Sizing

Face Seals
important criterion. The primary sealing interface is between rotating and stationary members that form a plane perpendicular to the shaft. The sealing area is a narrow ring where the two faces contact. One of the sealing faces is usually metal or ceramic and the other is usually graphite or plastic
