Foreword
This standard was compiled through revising the GB/T 10708.3-1989
“Reciprocating rubber seals – Types, dimensions and tolerances – Part 3.
Rubber dust seals”.
This standard is the first revision of GB/T 10708.3-1989, AND the main changes
are as the follows.
- In the B type seal ring size series and tolerance, ADD the size and tolerance
when the piston rod diameter is 56 mm;
- In the C type seal ring size series and tolerance, ADD the size and tolerance
when the piston rod diameter is 6 mm, 8 mm, 10 mm, 16 mm, 20 mm, 25
mm, 32 mm, 40 mm, 50 mm, 60 mm, 63 mm, 80 mm, 100 mm, 125 mm,
160 mm, 1 80 mm, 200 mm, 250 mm, 280 mm, 320 mm, 360 mm.
- MODIFY the arrangement format, symbol specification and labeling method.
This standard part 3 of GB/T 10708 “Reciprocating rubber seals – Types,
dimensions and tolerances”
GB/T 10708 includes the following three parts.
Part 1 (i.e. GB/T 10708. 1). Rubber seals of act on single seal;
Part 2 (i.e. GB/T 10708. 2). Rubber seals of act on double seal;
Part 3 (i.e. GB/T 10708. 3). Rubber seals for wipers.
This standard shall, from the date of implementation, replace GB/T 10708.3-
1989.
This standard was proposed by the former Ministry of Chemical Industry of
People's Republic of China.
This standard shall be under the jurisdiction of the National Rubber and Rubber
Products Standardization Technical Committee Sealing Products Technical
Branch.
The drafting organizations of this standard. Northwest Rubber and Plastics

Reciprocating rubber seals – Types, dimensions and
tolerances – Part 3. Rubber dust seals
Replacing GB/T 10708.3-1989
1 Scope
This standard specifies the type, dimensions and tolerances of the rubber dust
seals for reciprocating motion.
This standard applies to the rubber dust seals installed on the reciprocating
hydraulic cylinder piston rod guide sleeve for the purposes of dust proof and
sealing (abbreviated as dust ring).
2 References
The following standards contain provisions which, through reference in this text,
constitute provisions of this Standard. At the time of publication of this standard,
the versions shown are valid. All standards are subject to revision, and parties
using this standard shall explore the possibility of using the most recent
versions of the following standards.
GB/T 6578-1986 Hydraulic fluid power – Cylinder – Reciprocating –
Housings for rod wipers – Dimensions and tolerances
3 Classification and symbols
3.1 Classification
As for the dust rings as specified in this standard, they are divided into three
basic types based on structures and applications.
- A type dust ring, which is a single lip rubber seals without skeleton, AND
suitable for installing into A type seal structure for the purposes of dust
proof, as shown in Figure 1.
5 Marking
The marking is indicated by the "dust ring type symbol, d x D x L1 (L2, L3),
manufacturer code".
Example. The piston rod diameter (d) is 100 mm, seal groove outer diameter
(D) is 115 mm, AND the A type dust ring for which the A type seal groove axial
length (L1) is 9.5 mm, it is marked as. FA 100 x 115 x 9.5 XX.
