Oilless Technology: The Key to a Sustainable Future

Oilless technology refers to the design and engineering of machinery that operates without the need for traditional oil-based lubricants. Instead, various techniques are employed to minimize friction and ensure smooth operation.

Oilless technology offers a wide range of advantages over traditional lubricated machinery. Firstly, it eliminates the need for frequent oil changes and maintenance, leading to reduced downtime and cost savings. Additionally, oilless machinery experiences lower levels of wear and tear, resulting in a longer lifespan and increased reliability.

minimizes the risk of oil leaks and contamination, particularly suitable for industries where cleanliness is critical, such as food processing, pharmaceuticals, and electronics manufacturing.

Oilless Bearing Change Your Life

Oilless bearings, also known as self-lubricating bearings, can make your machine component stronger.

  • Reduced maintenance: Oilless bearings don’t require the same level of maintenance as traditional bearings, since they don’t need to be lubricated. This could save you time and money in the long run.

  • Longer lifespan: Because oilless bearings are always self-lubricating. they may have a longer lifespan than traditional bearings. This could mean fewer replacements and less downtime for your equipment.

  • Better performance: Self lubricating bearings can provide smoother operation, reduced noise and vibration, and improved accuracy. This could be particularly important in high-precision applications.

  • Environmental benefits: Since oilless bearings don’t require lubrication, they can reduce the risk of oil leaks and spills. This could be important for environmental and safety reasons.

Custom Your Oilless Bearing- Metric And Imperial Size

We provide the latest in machine tool technology to fuel your competitive advantage—from simple to complex and from prototype through to production.

Both metric and imperial dimensions can be used. The size of an oil-free bearing will depend on the specific application and requirements, such as load capacity and operating temperature.

To determine the appropriate size of an oil-free bearing, factors such as shaft diameter and housing bore diameter must be considered, as well as the bearing’s load capacity and operating conditions. Alternatively, you can email me to ensure that the selected bearing is suitable for the specific application.

Whether your needs are a fast turnaround of prototype components or higher volume product runs, VIIPLUS can help craft a solution. We are a company that prides itself on value, consistent quality, and on-time delivery performance along with our technical abilities in providing complex, close-tolerance machining operations.

Types of Precision Oilless Bearings

There are several types of precision oilless bearings available, each with unique features and benefits. Here’s a quick overview of the three main categories:

  • Metal-Polymer Composite Bearings, consist of a metal backing with a polymer-based self-lubricating lining. The metal provides high strength and durability, while the polymer layer offers excellent lubrication and low friction. This combination results in a bearing that is lightweight, corrosion-resistant, and capable of handling high loads.
  • Solid polymer bearings are made entirely from self-lubricating materials, such as PTFE or PEEK. These bearings offer excellent chemical resistance, low friction, and minimal wear. They are ideal for applications where weight reduction and corrosion resistance are critical, such as in the aerospace and medical industries.
  • Metal bearings, such as bronze or iron-based alloys, are embedded with solid lubricants, like graphite or molybdenum disulfide. These bearings offer high load capacity, excellent wear resistance, and good thermal conductivity. They are suitable for high-temperature applications and heavy-duty equipment.
