Black PU Abrasion Resistance O Ring Polyurethane Rubber Seals For Steering Wheel
What is O Seal ring ?
1.The O-ring is an annular seal having an O-shaped cross section, the size of which is determined
by the inner diameter ID and the wire diameter CS.
2.O-ring size calculation: outer diameter = inner diameter + 2 x wire diameter (OD = ID + 2x CS).
3.The purpose of using O-ring seals is to prevent leakage and loss of liquids or gases.
4.O-rings are the most commonly used type of seal because of their simplicity, convenience, and
small installation space. As long as the groove design and material selection are correct, and the
operating conditions are within the temperature range of the rubber material, the seal can have a
long-term sealing effect in the static or dynamic seal.
O-ring advantage:
O-rings have the following advantages compared to other types of seals:
-- Suitable for a variety of sealing forms: static seal, dynamic seal
Suitable for a variety of materials, sizes and grooves have been standardized, interchangeable
- Suitable for a variety of sports: rotary motion, axial reciprocating motion or combined motion
(such as rotary reciprocating combined motion)
- Suitable for many different sealing media: oil, water, gas, chemical media or other mixed media
Effective sealing of oil, water, air, gas and various chemical media through the selection of
suitable rubber materials and appropriate formulation design. The temperature range is wide
(-60 ° C ~ +220 ° C), the pressure can be up to 1500Kg / cm2 when used in fixed use (combined
with the reinforcing ring).
--Simple design, compact structure, easy to assemble and disassemble
The O-ring cross-section structure is extremely simple, and has a self-sealing effect, and the sealing
performance is reliable.
Since the O-ring itself and the mounting structure are extremely simple and standardized, installation
and replacement are very easy.
--More varieties of materials
Can be selected according to different fluids: nitrile rubber (NBR), fluororubber (FKM), silicone
rubber (VMQ), ethylene propylene rubber (EPDM), neoprene (CR), butyl rubber (IIR), HNBR
(Hydrogenate Nitrile) ,natural rubber (NR),CR/Neoprene/Polychloroprene , polyurethane rubber(PU) etc.
--low cost
--The dynamic friction resistance is relatively small
