The series of red bushings, designed with inch size splits, are
specifically tailored for hydraulic applications. These bushings
are manufactured from high-quality material, known for its
excellent lubricity, chemical resistance, and wear resistance.
The red color of the bushings not only provides a clear visual
indication but also helps to identify them easily during
installation and maintenance. The inch size splits allow for
precise fitment and adjustment, ensuring a secure and reliable fit
within the hydraulic system.
The material ensures smooth operation and reduced friction, which
is crucial in hydraulic systems. This reduces wear and tear on both
the bushings and the mating surfaces, extending the overall
lifespan of the hydraulic system.
The series bushings are suitable for a wide range of hydraulic
applications, including pumps, valves, and cylinders. They can
handle high pressures and temperatures, making them ideal for
demanding industrial environments.
In summary, the series of red bushings with inch size splits are an
excellent choice for hydraulic applications, providing superior
performance, durability, and ease of installation.

Hydraulic cylinder bushing & Cylinder Bushes
Red bushings offer good wear and low friction performance over a wide range of loads, speeds and temperatures in
dry running conditions.
Hydraulic bushings commonly used in automotive suspensions are
expected to damp low-frequency high-displacement vibrations,
and also contribute to high-frequency acoustic isolation from relatively small displacements.
Hydraulic bushings typically have two hydraulic chambers connected
by a channel.
The resonance of the fluid in the channel creates a mass-dampening
effect.
A one-piece intermediate tube is used in some designs to improve
the durability of the bushing and to separate the working part from
the elastomeric bushing where loads are removed from the outside of
the elastomeric bushing where the channels are formed and the fluid
seal
is provided for the fluid inside the bushing.
Hydraulic Bushing Feature
It is made of tin bronze as a matrix, sintered bronze spherical
powder in the middle and laminated and high temperature resistant filler materials
on the surface and combined with the principle of oil cylinder and
damper .
It has a high safety factor and is particularly suitable for places
where continuous work cannot be interrupted for repairs and
where high temperatures cannot be refueled, especially suitable for
frequent reciprocal occasions with a high inclination.
