Seal profile materialThe standard material for the profiles is the synthetic elastomer NBR 70. This material is characterised by :

good resistance to oils & grease

good wear resistance.

Operating temperatureExcel seal profiles can be used at temperatures from –40 °C to +80 °C.

Excel slewing rings are available in the following designs :with external gear teeth (A)

with internal gear teeth (I)

without gear teeth (U)

Material The slewing rings are made from normalised material C45N.

Design and quality of gear teethAs standard, the gear teeth on slewing rings are involute gear teeth without addendum modification (0 = 20°).

Heat treatment of gear teethThe heat treatment of the gear teeth is characterised by means of suffixes :

normalised (N) - standard design of gear rings

quenched and tempered (V) - special design of gear rings

hardened (H) - special design of gear rings.
