The coated ISC O-Ring from Simrit

Benefits of the coatedISC O-Ring: Simplified Assembly

Reduced insertion force

Suitable for dynamic

Applications

Improved reliability inthe assembly process

The resulting reduction incontact friction with a coated

ISC O-Ring prevents the ad-

hesion to machine parts during

the feed process. Sticking of

the individual O-Rings is also

avoided in this process step.

The coated ISC O-Ring,X-Ring and specialdesigns from Simrit arethe optimal sealingsolutions for meeting thecustomers technicalrequirements. This notonly involves require-ments regarding the

actual use of seals butalso demands on up-stream processes suchas handling, separationand the installation ofsealing components.

Compared to oiled O-Rings, the

possible introduction of conta-

minants to the subassembly

by foreign particles is greatly

reduced through the use of

a coated ISC O-Ring. During

assembly damage to the

ISC O-Ring is avoided thanks

to low friction coefficients as

well as the rings tendency totwist.

Overall the coated ISC O-Ring

makes a major contribution

to a smooth running production

process.

Range of coatings:Surface Coating (SC)families of the ISC O-RingThe different SC families are

geared to individual key

requirements. Within every

SC family there is a wide

range of coating variants

characterised by graduated

modification. This allowsapplication-specific require-

ments to be taken into account.

There are also numerous

standard approvals (KTW,

FDA etc).Surface of coated ISC O-Ring showing the example of the

Reliable assemblythrough reduced frictionThe friction forces occurring

during assembly are greatly

reduced with the coated ISC

O-Ring. This means the risk of

damage to the ISC O-Ring is

much lower during assembly.

Installation and dismantling

also become faster thanks tothe coating. When a coated

ISC O-Ring is used for a plug

system, very low forces are

required for assembly. With

Surface Coating A (SCA) for

example, the low friction and

insertion forces are reduced

by approx. 85%.

Low stresses on theISC O-Ring and system

Low friction is very importantfor dynamic applications using

ISC O-Rings. There is a marked

reduction in friction on the

O-Ring, thus increasing the

service life to a major extent.

For example, with Surface

Coating B (SCB) the friction

level in dynamic applications

is reduced by some 75%.

Economic benefits for the customer

Savings thanks tooptimised assemblyEach year a customer fits

2.2 million O-Rings in his pro-

duction facility. The fitting path

for the O-Ring is 20mm, which

resulted in twisting, incorrect

assembly and in certain cases

damage to the O-Ring. The use

of a coated ISC O-Ring allowedthe assembly defect rate to be

reduced from 3% to 0.02%.

The result was a major fall in

the number of defective compo-

nents being detected during

the final inspection. There was

also a marked reduction in the

inspection work involved for

failure analysis as well as for

the rectification of defective

components through the dis-

mantling and renewed perfor-mance of the assembly process.

In addition to these improve-

ments it was possible to reduce

the assembly time by 4%.

This was achieved via worker-

friendly assembly with lower

friction levels and a shorter

time requirement for O-Ring

separation.

Alone the direct economic over-all benefit to this customer from

the above effects amounted to

45,000 per year.
