O-ring application introduction:
YX type O-ring for hole
Product use: used for the sealing of pistons in reciprocating
hydraulic cylinders. Scope of application:
TPU: general hydraulic cylinder, general equipment hydraulic
cylinder. CPU: Hydraulic cylinders for
construction machinery and cylinders for high temperature and high
pressure. Material: Polyurethane
TPU, CPU, rubber.
Product hardness: HS85±2°A Working temperature: TPU: -40~+80°C,
CPU: -40~+120°C Working
pressure: ≤32Mpa Working medium: hydraulic oil, emulsion.
YX type hole with O-ring
Product use: This standard is applicable to the use of YX-type
sealing ring when the working pressure
of the cylinder is greater than 16MPa, or the function of
protecting the sealing ring when the cylinder
is eccentrically stressed. Working temperature: -40~+100 degrees.
Working medium: hydraulic oil,
emulsion, aquatic product hardness: HS92±5A Material:
polytetrafluoroethylene.
YX type O-ring for shaft
Product use: For the piston rod of the reciprocating hydraulic cylinder, the
scope of application: TPU:
general hydraulic cylinder, general equipment hydraulic cylinder.
CPU: Hydraulic cylinders for
construction machinery and cylinders for high temperature and high
pressure. Material: Polyurethane
TPU, CPU, rubber Product hardness: HS85±2°A Working temperature:
TPU: -40~+80°CCPU:
-40~+120°C Working pressure: ≤32Mpa, working medium: hydraulic oil,
emulsion.
O-ring sealing performance is excellent, working life is high,
dynamic pressure sealing working life is
5-10 times higher than conventional rubber sealing products, up to
several tens of times, under certain
conditions can be the same life as the sealing substrate.
The O-ring has low frictional resistance and equal dynamic and
static friction. It is 1/2-1/4 of the friction
of the "0"-shaped rubber ring, which can eliminate the "crawling"
phenomenon of low-speed and
low-pressure movement.
The O-ring is highly wear-resistant and has an automatic elastic
compensation function after the sealing
surface is worn.
O-rings have good self-lubricating properties. Can be used as an
oil-free lubrication seal.
The O-ring has a simple structure and is easy to install.
O-ring working pressure: 0-300MPa; working speed: ≤15m/s; working
temperature: -55-250 degrees.
O-ring suitable medium: hydraulic oil, gas, water, mud, crude oil,
emulsion, water-ethylene glycol, acid.
