Agricultural Machinery Reliable for yearsSimmerrings are sturdy heavyduty machine elements. Theyowe their high levels of relia-bility to the many years ofdevelopment work undertakenby Simrit. To cater for the specific requirements involvedwith applications that are exposed to dirt and intrusionthere are 3 types of Simmerring®

Cassette Seals available.

SimmerringCassette SealsThe versatility of our brandproducts is a key factor duringdevelopment. This applies to dimensional range as well as toquality. Our wide range of diameters and overall heightsoffered by Simmerring CassetteSeals ensures the seals are suit-able for different applicationsand operating conditions. The selection criteria include aspects such as soiling levelsand circumferential speed. Typical applications and theseals recommended by Simritfor these purposes are shown inthe adjacent tables. In the caseof high or special loads we recommend selecting seals inconsultation with ourselves, a process in which tests of functional reliability are oftenindispensable.

A closed sealing system with numerous benefits

The service life of seals may begreatly impaired by a contami-nated environment. Simmerring®

Cassette Seals have been spe-cially developed for extreme soil-ing levels and have proved theirworth in many applications.

The benefits of Simmerring Cassette Seals at a glance■ reliable static and dynamic sealing■ perfectly coordinated and precisely greased sealing lips■ incorporation of an effective labyrinth■ simple replacement of seal without refinishing of the shaft■ incorporation of a slip ring, thus involving no costly shaft treatment

(no hardening or grinding required)■ simple fast fitting without damage

Simmerring Cassette Seals consist of two components,a Simmerring and a slip ring.They have been joined togetherto prevent any detachment.
