Sliding bushings, specifically those constructed with polymer plain
sleeve bearing strips and metal-polymer composites, offer a unique
combination of durability and maintenance-free operation. These
bearings are designed to provide smooth, friction-free movement in
various industrial applications, reducing wear and tear on
machinery while enhancing overall performance.
The polymer material used in these bushings is known for its
excellent wear resistance and low-friction properties. This allows
the bearings to operate with minimal heat generation and reduced
wear, even under high loads and speeds. The metal-polymer composite
construction further enhances the durability and stability of the
bushings, ensuring reliable performance over extended periods.
The maintenance-free design of these bearings significantly reduces
operational costs and downtime. Unlike traditional bearings that
require regular lubrication and maintenance, these polymer sleeve
bearings require minimal upkeep, allowing for increased efficiency
and productivity.
Wh you're upgrading existing equipment or installing new machinery,
sliding bushings with polymer plain sleeve bearing strips and
metal-polymer composites are an excellent choice for improving
operational efficiency and reducing maintenance requirements.

how they can enhance your industrial operations.
Non-lead boundary lubrication bearing is improved on the basis of
LIKE DX BUSHINGS.It can be applied to the field where non-lead is
required.Now it's widely used in textile machines,auto operating
parts and other middle speed,middle load and grease lubrication
occasions.
The structure of this self-lubricated bearing material strip plate
sheet consists of spherical powdered bronze sintered onto a steel
backing and POM polyacetal resin impregnated into the surface.This bushing is
filled with lubricant before installation, to which a small amount
of lubricant is added at predetermined intervals to allow it to
withstand long-term operation.
Plain Bearings & Sliding Bearing Strips
Our VIIPLUS range of bearing strip is suitable for rotary and oscillating
movement applications.
The VIIPLUS bearing strip is made from carbon steel with a sintered bronze
layer and an acetal co-ploymer layer.
Our machining service is able to produce non-standard sizes to suit
customer specific requirements.
Please contact us for information on sizes.
Low friction for smooth rotation at startup and at low speed under high load
conditions.
Seizure-free sliding surfaces.
Excellent shaft misalignment tolerance.
Ability to withstand impact loads.
Low friction.Damage prevention to shaft.
Virtually wear-free bearing surface with minimal lubricant.
VIIPLUS range of wrapped POM lined bearings are suitable for rotary and
oscillating movement applications. They benefit from long
re-lubrication intervals, no absorption of water, outstanding
damping behaviors and have a low suceptibility to edge loading.
Strips PAS are available as an even material section. This material
section can be used to make sliding elements in a variety
of shapes.

Thrust washers
Strips
Our wrapped Ploymer lined bearings have a high wear resistance and
low friction even with very small quantities of lubricant
The surface carries a pattern of circular indents which should be
filled with grease on assembly
Low carbon steel gives exceptionally high load carrying capacity and excellent heat
disspation
Our VIIPLUS range of wrapped acetal bearings can hugely reduce maintenance
costs on projects large and small and are stocked in metric plain,
imperial plain, metric washers. Imperial washers, metric strip and
imperial strip.
