Types of Engineering Plastic Bearing

Flange bearings

Flange bearings are designed to handle both axial and radial loads. In some designs the flange is also used as a locating mechanism to hold the sleeve portion in place.

Mounted bearings

Mounted bearings come in the form of pillow block or flange style housings. These can be in many different forms with 2, 3 or 4 mounting holes. Mounted bearings can be retrofit with several different plastic plane bearing materials to improve wear and reduce or eliminate lubrication.

Thrust bearings

In plane bearing speak thrust bearings are simple washers made from any number of materials. These are generally thin, easy to install and prevent metal on metal contact in any thrust load conditions.

Sleeve bearings

The most common plane bearing, sleeve bearings, are simple ID/OD/Length cylinders that are designed to carry linear, oscillating or rotating shafts. The key to successfully designing a plastic sleeve bearing is paying attention to temperature, P, V and PV ratings for the material and match it with your application.

Spherical bearings

Spherical bearings are designed to allow for shaft misalignment, as they can rotate from two directions. Spherical bearings typically support a rotating shaft in the bore that calls for both rotational and angular movement.

Features of Engineering Plastic Bearing

Lightweight

Suitable for aerospace, automotive, and robotics industries where weight reduction is crucial due to its light weight.

Corrosion Resistance

Does not rust and shows minimal performance degradation when exposed to moisture or chemicals.

Self-Lubricating

Capable of operating without lubrication, which helps maintain cleanliness and reduces maintenance costs.

Low Noise

Generates less noise during operation compared to metal bearings, making it suitable for applications such as medical devices and home appliances where noise reduction is important.

Non-Magnetic

Non-magnetic, allowing use in environments where magnetism is a concern.

Custom Engining Plastic Bearing Manufacturing Services

If customer have the drawing, which includes the dimensions, materials, special requirements, then we can make the mold according to the drawing.

If customer have no drawing, we can design according to customer request, to make a drawing and get confirmation from customer. Then we make a mold according to the drawing.

After test the mold, if the mold is ok. Then make the samples, our engineer will measure the After samples confirmed, we will make documents and book vessel to ship to customer , sometime if urgent by air.

The production flow as bellow

Raw Material booking → Raw material testing → Turning process → Heat treatment → Grinding process → Products inspection → Super grinding process → Bearing rings cleaning process → Bearing assembly → Bearing cleaning → Bearing greasing/sealing process → Quality inspection → logo marked–package

Then we will ship our goods, small quantity, usually by express transport , such as FedEx , DHL, TNT, UPS, or by air. If large quantity, usually by ship or land transport ,or by air .

Packaging & Delivery

• Delivery time: 5-25 working days, depend on the quantity of order.

FAQ

Q: What is the best material for plastic bearings?

A: Nylon's strength, wear resistance, and self-lubricating properties make it a go-to material for various bearing applications. Its adaptability to diverse operational environments further solidifies its standing as a reliable choice for plastic bearings.

Q: What are plastic bearings?

A: Plastic ball bearings are bearings built from plastics, such as nylon, acetal, and PTFE. They can be self-lubricating when combined with carbon graphite and other non-metallic materials.

Q: Which plastic is used for making engineering component bearing?

A: Polyamide – PA (Nylon)
Nylon is one of the most widely used materials for simple bush-style bearings as it has a low coefficient of friction and is self-lubricating which eliminates the need for additional lubrication. It is also inexpensive in comparison to some other engineering plastics.

Q: Do plastic bearings need lubrication?

A: Corrosion is also no problem – at least for the bearing itself. And yet lubrication nevertheless is often indispensable. Lubrication allows plain bearings to move smoothly. It also prevents corrosion, dirt entering the bearing and temperature increases due to friction.

Q: What are the application of plastic bearings?

A: Plastic bearings are used in the marine industry and depending on the ball and cage materials, can be permanently submerged in seawater. Acetal resin bearings with 316 stainless steel or glass balls have very good resistance to seawater but can only be used in lower precision, low load and low speed applications.
