ERIKS also supplies the types GR and GRST. These are virtually identical to the types R and RST, except in this case the metal inner ring is also completely encased in rubber. ERIKS uses FKM rubber here as standard, so these seals are ideal for use in acidic environments.

The most important function of an oil seal is to protect all types of sleeves, roller bearings, and balls located in the rotary shafts. These seals also prevent two fluids from mixing, such as water and oil.

Bauerle and Bruhnke⁷ found that aeration reduces the effect of oil additives on fluoroelastomer properties. Some of their data is reproduced in Fig. 14.4,⁵ showing the effect of aeration of an SF-grade 5W30 oil on the retention of elongation of a VDF/HFP copolymer (FKM-E430), a VDF/HFP/TFE terpolymer (FKM-B600), and a VDF/PMVE/TFE fluoroelastomer (FKM-GFLT). The HFP-containing polymers show much better retention of properties with aeration.

ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
