Installation of Simmerring Combi Seal
Bore requirements for all COMB±s which has not elastomer on
the outer diameter (ex. SF5 and SF6)
Tolerance:
ISO H8
Chamfer:
20° ± 5° x 1,5 mm (0.06 in)
Roughness:
R
a
= 0,8 … 3,2 µm
R
z
= 6,3 … 16 µm
R
max
< 16 µm
Shaft requirements
A
The requirements for Standard Simmerring are valid
A
Shaft hardening required.
Handling
A
Proceed carefully and ensure that the sealing lips are not
damaged during handling and when inserting the shaft
(this applies especially to spline shafts).

outer diameter (ex. SF19 and SF8)
Tolerance:
ISO H8
Chamfer:

Roughness:
R

Fitting procedure
A
The same installation instructions as for Standard
Simmerring are valid
A
Use care when inserting the shaft so that the polyurethane
lip does not bend
A
Please inquire for removal instructions (air side first).
Replacement
A
If a Simmerring Combi Seal is replaced, the shaft must be
replaced/renewed to fulfil the roughness, hardness and
tolerance requirements
A
For Standard Simmerring Combi Seal SF5 and SF6, a
sealant on the outside diameter is required.

Handling
A
The spring may not be removed
A
Do not attempt to open the seal
A
Store the seals stacked.
