This will help prevent the X-ring from spinning with the rod and staying in the groove. In rotary seals it is also important to make sure the surface finish of the spinning rod is smoother than the groove. 10mm x 1mm (12mm OD) Nitrile O-Rings Inner Diameter 10.0mm Outer Diameter 12.0mm Cross Section 1.0mm Tolerance () 0.1mm Material Spec Material Nitrile. A custom backup must be used if it is required for an application. Due to the symmetrical shape, the X-ring can withstand stresses from multiple. Since the groove is designed deeper than an O-ring groove, standard backup rings will not work in an application with X-rings. The X-ring is a symmetrical four lobe seal, with a square fitting cross section. While X-rings do have many advantages in dynamic applications, there are some cautions to using X-rings in dynamic applications. We design and manufacture custom shapes and develop specialty materials to deliver a performance advantage. X-rings in rotary seals should also be made of 80 or 90 durometer material. X Rings Size005 - 3/32 ID x 7/32 OD x 1/16 CS Buna Nitrile rubber is considered the standard for most general applications. Nearly all custom size O-Rings, washers, square rings, and X-Rings in almost every material are supplied without tooling fees. X-rings work best if the rotational speed is kept below 6.5ft/s, the pressure is below 150psi, and temperatures are within -30☌ – 100☌. When designing an X-ring in a rotary gland, just like with O-rings, it is always recommended to design the X-ring as a female seal. We supply seal products to a variety of industries such as: dump and refuse trucks, construction equipment, material handling, industrial plant applications, farming, and logging equipment. X-rings can also be used in rotating glands, even though reciprocating glands are where their advantages really shine. The O-ring Store is a distributor of hydraulic seals, seal kits and cylinders for mobile and industrial applications. This allows for sealing in a much wider range of dimensional variation in both the mating hardware and the X-ring. Thus, the need for size standards which cover the most common sizes used. If the o-ring, quad-ring, x-ring or square-ring you need doesn't fit these standards, custom. Whether your application conforms to U.S., Japanese JIS, British BS, or Common Metric sizing for o-rings, these o-ring size charts will help you locate the right o-ring size. Because of its popularity, there is virtually an unlimited number of possible sizes of an o-ring. The proper o-ring size is a fundamental aspect of proper o-ring performance. O-Rings are used in a variety of applications in different industries around the world. For one, it is recommended to use the largest possible cross section of X-ring due to the fact that larger cross sections can handle a wider range of tolerance variance. An o-ring is one of the most common types of seals in the world. In addition to what was previously mentioned, there are some additional design considerations when creating a reciprocating gland for an X-ring. This is the largest advantage X-rings have compared to O-rings in dynamic applications. Due to the design of the profile, X-rings are not prone to spiral failure in reciprocating applications.
