Oilless bearing is a new type of bearing with the characteristics of metal bearing and oil - free bearing. As a supplier of plain bearings, the oil-free bearings also become the industry benchmark.

The high-performance dry friction bearing in China can run without oil or less oil through the low friction packing in the sliding layer. Lubrication has always been a headache for industrial designers. It is expensive and brings a lot of pollution, which is very unfriendly to the environment. This article will introduce the knowledge of lubrication and the specific application of VIIPLUS oil-free bearing.

Disadvantages of lubrication

1:increase the cost; Processing oil lines or oil lines in the shaft or housing, purchasing lubricating oil, reducing operating efficiency during maintenance due to machine downtime, additional sealing to maintain lubricant, recycling of machines, and so on all cost you a lot.
2.: reduce the oil seal and shaft between the contact energy efficiency.

3: add lubrication and use in the process of environmental pollution risk.

Stainless Steel 316 Bushings Applications

Bushes are suitable for Chemical valve, chemical pump, flow meter, food industry, medicine industry in the corrosion environment.transmission, rotational and oscillating movements. Rod guide for pneumatic and hydraulic cylinders.Attachment lugs of pneumatic and hydraulic cylinders.Conveyor-belt systems, textile machinery, automobiles. 


  • Standard cylindrical bushings, flanged bushings, thrust washers, and strips are available
  • Special designs are produced at short notice
  • Lead-free type is also available



Why Is Stainless Steel Bushings Corrosion Resistant? – Industrial Steel Bushes 304 Vs 316 Stainless Steel Bushings

Low friction and high wear resistance with no lubrication.

Stainless steel bearing uses the PTFE or PTFE fibers fabric and aramid fiber overlay on metal backings, the fabric has very high load capacity and high accuracy good run with low speed and heavy friction superior performance, widely used in heavy equipment like construction machinery, agriculture machinery.

Stainless Steel 316 Bearings +PTFE Fabric stainless steel-based non-oil lubricated

Viiplus Is A Professional Production Of Stainless Steel Bushing Manufacturers. Bearings and shafts made of stainless steel and are maintenance-free.

Stainless Steel Bushings That Can Withstand Moisture And A Number Of Corrosion Caused By Other Media. We produce bearing made of stainless steel 304&316. Characteristics of high strength, wear resistance, corrosion resistance, and corrosion resistance, etc. Stainless steel backing sintered with bronze powder overlaid with PTFE fibers fabric Suitable for dry running, low coefficient of friction, lower wear.

Industrial Steel Bushes 304 Vs 316 Stainless Steel Bushings

304 and 316 stainless steel bearing material is different: corrosion resistance: 316 stainless steel bearing Mo, then 304 stainless steel bearing in the high-temperature environment corrosion resistance is better, so in the high-temperature environment, engineers will generally choose 316 material parts.316 mainly reduced Cr content, increased Ni content, and increased Mo2%~3%. Therefore, its corrosion resistance is stronger than 304, suitable for use in the chemical industry, seawater, and other environments


Typical Applications

This material meets the demanding criteria for long life and trouble-free performance with or without lubrication.


  • Automotive: tractors, combines, crop sprayers, earthmovers, graders and other construction, auto machines, specific uses in power steering cylinders, steering gear thrust washers, disc brakes, calipers and pistons, shock absorbers, governor linkage, windshield wiper motor, tilt gear assemblies...

What Is Composite Bearing?

Composite dry sliding bearings are primarily used for bearing arrangements where heavy loads have to be supported and where rotational or oscillating movements are relatively slow.


Where To Use Composite Bearing?


Because of their good sliding properties and compact design, these plain bearings are particularly suitable for bearing arrangements where:
Maintenance-free operation is a prerequisite
There is a risk of lubricant starvation Lubricants cannot be used or are forbidden Space is limited.


Why Choose Composite Bearing?


Maintenance-free operation


No lubrication required (PTFE composite)

Initial lubrication required (POM composite)

Minimum wall thickness, minimum space requirements

Accommodation of heavy loads

Wide range of temperatures

Good sliding properties

Virtually no stick-slip

High wear resistance

Less sensitive to edge loading (POM composite)

No machining required.


Which Sizes Bearings We Can Offer You?


The standard range of composite plain bearings is very comprehensive and covers almost every standard size. This range comprises straight and flanged bushings, thrust washers, and strips.
