Composite Bushings POM Metal Polymer Plain Bearings Grease Lubricated are a high-performance solution for a wide range of industrial applications. These bushings are made from a combination of POM (Polyoxymethylene) metal and polymer materials, which provide exceptional strength, durability, and wear resistance.
The POM metal component offers a rigid and stable base for the bearing, ensuring accurate alignment and load distribution. The polymer material, on the other hand, provides a low-friction surface that reduces wear and heat generation, leading to longer bearing life and smoother operation.
The grease lubrication feature of these bushings further enhances their performance. The grease acts as a lubricant, reducing friction and wear even under high loads and speeds. This not only extends the lifespan of the bushings but also improves the overall efficiency of the machinery.
The plain bearing design of these Composite Bushings POM Metal Polymer Plain Bearings Grease Lubricated allows for easy installation and replacement. They can be used in a variety of applications, including pumps, motors, gearboxes, and other rotating or reciprocating equipment.
In summary, Composite Bushings POM Metal Polymer Plain Bearings Grease Lubricated offer a robust and reliable solution for industrial applications that require high-performance bearings. Their combination of strength, durability, wear resistance, and lubrication properties ensures smooth operation and long-lasting performance.
self-lubricating pom bushing, Precision Machining Services
We can efficiently create self-lubricating pom bushing and bearings in a variety of configurations necessary for your applications.
Now Offering Large Diameter Bushing Capacity.
VIIPLUS bearings utilize special polymer liners for self-lubrication and improved wear properties. Each material has a specific wear rate dependent on the speed, load, temperature, lubrication and hardware of the application. The metal backingsupports liner materials made to withstand high loads, speeds and adverse environments. The advantage of the VIIPLIUS design is that even if wear-thru occurs in the liner,
the supporting interlayer is a self-lubricating material as well.

POM composite dry sliding bushings Suitable for rotational and vibrational movements, less maintenance requirements due to longer relubrication intervals, shorter wear,lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.Pom composite dry sliding bushing, Ring maker, Mfg Bushes, The Pom composite dry sliding bushing is based on a composite material with 3 firmly bonded layers: steel as a base, spherical sintered bronze powder as an intermediate layer and modified POM as a coating layer. It is well suited to low speeds, difficult operating conditions and normal temperatures, it saves costs and extends its service life with the normal replacement of all copper rings.
It is especially suitable for rotating and swaying motion under heavy load and low speed, as well as opening and closing under load, which is not easy to form fluid lubrication.Under the condition of boundary lubrication, it can be used for a long time without refueling and maintenance.The plastic layer on its surface can leave a certain amount of margin in the shaft sleeve forming process, and can be processed by itself after pressing into the hole, so as to achieve a better assembly size.
At present, it is mainly used in metallurgical machinery, mining machinery, water conservancy machinery, automobile chassis, construction machinery, agricultural machinery, steel rolling machinery and so on.
1. The mixture of modified POM and lead is 0.3-0.5mm, which has high wear resistance and low friction coefficient even in the case of instantaneous oil shortage.Pom composite dry sliding bushing surface is arranged regularly with spiral Angle of oil storage pit, assembly, must be covered with grease.
2. Copper powder layer 0.2mm ~0.3mm, with good bearing capacity and wear resistance, good thermal conductivity can timely transfer the heat generated in the process of bearing operation.The composite material can infiltrate into the gap of the copper powder ball and improve the bonding strength.
3. Low carbon steel 0.4~2.2mm, improve bearing capacity and heat transfer.
4. Copper/tin plating, copper plating 0.008mm, tin plating 0.005mm,so that the bearing has a good corrosion resistance.
The superior performance of smooth polymer metal rings is based on their unique composite structure:
·Impregnated anti-friction coating enriched with and fillers or extruded thermoplastic tape
·Porous sintered bronze spacer for high wear resistance
·Steel or bronze support for high mechanical resistance
The Dry sliding Bushing sleeve can be used in rotating and swinging applications. Lower maintenance requirements thanks to long relubrication intervals. Less wear, less susceptibility to edge loading and no water absorption. THX has good damping qualities and is resistant to shock loads.
