Crusher Sealing Ring Chart

Due to the fact that there are literally dozens of oring standards globally finding a single recognized standard for metric oring tolerances is virtually impossible after extensive research we have adopted the tolerances shown in the following table which are based in iso 36011 class b annex a4

Seal ring is compressed radially and is pressed against the shaft by the groove diameter the seal ring is thus slightly corrugated in the groove a fact which helps to improve the lubrication the rotary seal principle can be neglected at peripheral speeds of less than 05 ms

Oring hardness the hardness of an oring is important for several reasons the softer the elastomer the better the seal material conforms to the surfaces to be sealed and lower pressure is required to create a seal this is particularly important in low pressure seals that are not activated by fluid pressure

The face seal design chart below explains the hardware dimensions to use for an oring seal when the groove is cut into a flat surface for designing systems which contain internal pressure like the example below the grooves outside diameter od is primary and

Will also be different if the oring is sealing a liquid which has a low volume swell on the ring 015 design chart 1amp3 or if it is sealing a liquid which has a high volume swell on the ring 1525 design chart 2amp4 it has not been practical to attempt to seal liquids which will swell the oring more than

2 clamps 2 hubs 1 seal ring 4 studs and 8 nuts the seal ring is a zero leakage reusable metaltometal gasket interfaced with the hub sealing surface to ensure high integrity and a reliable seal the joint configuration ensures that the seal ring is elastically loaded during assembly to offer a self energized seal during operation

Seal assembly consists of an elastomer oring and a gland an oring is a circular crosssection ring molded from rubber figure 11 the gland usually cut into metal or another rigid material contains and supports the oring figures 12 and 13 the combination of these two elements oring and gland constitute the classic o

The seal will be exposed to and check oring material resistances in chemical compatibility tables listed in the apple seal design guide 3 list all factors of seal application and check material performance a pressure determines material hardness and selection b heatcold check material temperature ranges c friction determines

Need to prevent oring extrusion fig1 oring extrusion from differential pressure oring extrusion is rare at conditions lying to the left of a seals performance line for example a 70durometer seal with 0005 inch gap d0010 will seal to 800 psi but may extrude at higher differential pressures for higher

Oring in the smallest possible groove ie at the hardware and oring tolerance stackup and the smallest possible oring in the largest possible groove oring gland types and nomenclature most static oring seals can be classied into one of the three arrangements shown below the variable names pistontype seal facetype seal rodtype

To accommodate these forces a quadring174 brand seal uses a narrower groove than a comparable oring seal longer seal life because less squeeze means less friction with the fourlobe design seals last longer therefore equipment in which the quadring174 brand seal is installed will operate longer and require less maintenance

14 oring size charts note the as oring size chart has a column that shows the nominal size alongside the actual size originally the nominal size was just for a listing of the approximate fractional dimensions of the oring prior to the common use of dial calipers many people called out a 1 inch by 114 rt oring this was a dash 214

An oring is a solidrubber seal shaped like a dough nut or torus when compressed between mating surfaces an oring blocks the passage of liquids or gases orings are available in a wide range of standard and nonstandard sizes that are suitable for nearly all sealing applications

A sealing lip made of an elastomeric or thermoplastic material that seals dynamically and statically against the shaft the lip has a sealing edge that is formed by moulding cutting or grinding it is normally pressed against the counterface surface of the shaft with a defined radial load by a garter spring

2 other installation methods one auxiliary oring is fixed between the conical ring surface of the floating oil seal and sealing oring as shownthe ring of the floating oil seal is applied uniformly by pressure and the auxiliary oring braces the sealing oring to ensure the other correct mounting positions

Quattro174 seal orings feature 4 sealing surfaces to help reduce the amount of squeeze required to create a positive seal they also help reduce friction and extend seal life black color all conform dimensionally to as568 oring sizes
