RDD200250-T46N

Trelleborg Double Delta® combines the flexibility and response of O-Rings with the wear and friction characteristics of the Turcon® materials in dynamic applications. The double acting performance of the seal follows from the symmetrical cross section which allows the seal to respond to pressure in both directions. Initial contact pressure is provided by radial compression of the O-Ring. When the system pressure is increased the O-Ring transforms this into additional contact pressure, the contact pressure of the seal is thereby automatically adjusted so sealing is ensured under all service conditions.

Material Information for the product(s) on this page

N7

Material data sheet

Colour:

Black

Basic Material:

NBR

Commercial Description:

A 70 durometer, NBR elastomer. The properties of the nitrile rubber depend mainly on the ACN content which ranges between 18 % and 50 %. In general it has good mechanical properties with an operating temperature range of between -30 °C and +100 °C. NBR is mostly used with mineral based oils and greases and is a good choice for standard applications. Used also as an energizer in T46N, M12N, Z20N, and Z52N.

T46

Material data sheet

Colour:

Greyish to Dark Brown

Basic Material:

PTFE

Filler:

Virgin PTFE compounded with Turcon® and bronze

Commercial Description:

Turcon® T46 is a blend of PTFE, bronze, and a proprietary Turcon® filler and is backed by years of time-tested performance and offers a balance of performance and cost. This material has a high extrusion resistance and has very good wear properties. For medium to heavy applications with reciprocating movements in mineral oils and other media with good lubrication. Used in article numbers ending in T46N and T46V.
