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. Contact us today to learn more about these innovative bearings and how they can enhance your industrial operations.
Sliding Bushings Ploymer Plain Sleeve Bearing
Non-lead boundary lubrication bearing is improved on the basis of LIKE POM 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.

VSB-20 Strips, Slide Bearing Strip
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.
Features
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.
Characteristics
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.
- Cylindrical bushes
- Thrust washers
- Strips
Strusture
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.
