Self Lubricating Plain Bearing Dry Sliding Bushing

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.

Sintered porous bronze on metal substrate with POM calendared into the dynamic wear surface.Requires boundary lubrication for optimum performance . High PV rating,Low speeds. Commonly used in mining equipment, rolling mills, skilifts and other applications where bronze bushings are utilized.

International supply of technical industrial goods, in particular wrapped sleeves (self lubricating or for lubrication), personalized POM bushes, 

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.

The superior performance of smooth polymer metal rings is based on their unique composite structure:
·Impregnated anti-friction coating enriched with PTFE 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.

Operating Performance
 

Use Note

·Due to their good sliding properties and compact design, these composite dry sliding bushing are particularly suitable for pom composite dry sliding bushing arrangements where:
·Maintenance-free operation is a prerequisite
·There is a risk of starvation of the lubricant
·Lubricants may not be used or prohibited.
·Space is limited.

Pom composite dry sliding bushing are mainly used for bearing devices where it is necessary to withstand heavy loads and where rotational or oscillatory movements are relatively slow.

Application

Recommended for applications involving intermittent operation or boundary lubrication.

Automotive: suspension joints, kingpin assemblies, automobile driving joint hinges, steering and other linkages, articulation
joints, and rear chassis hinges.

Machine Tools: spindles in drill, grinding, and milling machines,and ram guide plates in multi ram presses.

Agricultural Equipment: gearboxes, clutch assemblies, bale trips and wheel caster swivels for bale accumulators, front axle pivot bearings, steering idler box bearings and kingpin bearings for harvesters...

The pom composite dry sliding bushing is especially well suited for applications where lubricant cannot be supplied continuously or repeatedly.

Availability

Standard cylindrical bushings, thrust washers, flanged bushing and strips are available.

Metric bearings and imperial bushings made to order: standard bushing forms in special dimensions, half-bushings, special shapes obtained by stamping, bearings with locating notches, lubricant holes and machined grooves, customized bushing designs
