Top Benefits of Plastic bearings
Material handling is an essential part of the success of any company in the manufacturing, processing, and shipping of products. An enterprise requires systems that can improve efficiency overtime to do this effectively. Production output must continue to move and conveyor systems and components must do so too to ensure this.
Many engineers do not feel that plastics can handle difficult applications or environmental factors. Yet plastic conveyor bearings can withstand extreme temperatures, heavy loads, and high velocities. It is necessary, however, to consider both the benefits and the drawbacks of the available options.
Self-lubricating polymer bearings contain solid lubricants found in the fiber-reinforced material’s millions of small chambers. The bearing can move lubricant onto the shaft during operation to help lower the CoF. Like a bronze-sintered bushing, polymer bearings release solid lubricants as soon as the bearing or shaft is pushed.
Inside the bearing, the fiber-reinforced materials withstand any high forces or edge loads. Even plastic bearings can be used on several different types of shafts.
Modern plastics can carry benefits over conventional metal applications. Choosing to use plastic over other more conventional materials will give longer life, decreased maintenance costs, and lower energy consumption, depending on the application. Let’s check the benefits of plastic bearings.
- Reduces weight
Plastic is much lighter than those used in most bearings for carbon or stainless steel. The weight of plastic material is around 20% of standard steel bearings.
Plastic is cheaper than other metals. In most cases, it is up to 25% cheaper. In several applications, plastic bearings may also substitute more costly alternatives with high wear resistance and a low friction coefficient.
Plastic bearings have a self-lubricating feature that removes the need for manual lubrication and facilitates longer lifespan. Offering a great combination of strength, corrosion-resistance, and grease-free operation in linear, oscillating, and rotary applications, a plastic bearing that is ideal for your application is likely to be fine.
The plastic bearings that have a long lifespan after installation and do not need to be replaced as quickly as any other alternative. The downside to metal bearings-corrosion will freeze them in place, rendering them nearly impossible to remove without cutting. The upside is found in the use of plastic bearings, as they can be removed easily.
- Durability and strength
Plastic bearings are designed for extended use and can last much longer than steel, enabling food processors to reduce production line maintenance costs.
- Chemical resistant
As well as being resistant to corrosion, plastic bearings are also chemical resistant! Plastic bearings are more resistant to various liquids and chemicals than their metal counterparts. They also avoid the scratching and wearing that takes place with metal bearings. This ensures that their low friction coefficient is retained, working smoothly with minimal interference.
- Temperature Tolerance
Most plastic bearing compounds work easily at temperatures ranging from freezing to 500 ° F, which is suitable for use in a wide variety of food processing. Metals generally have a limited range of temperatures or require expensive, specialized, high-temperature food-grade lubricants.
- Noise control
Plastics have the innate ability to dampen lubricating vibrations, being virtually silent.
- Suppression shock load
Plastics are elastic, making them stronger at handling shock loads than metals.
Multiple reasons to use plastic bearings
Plastic conveyor bearings are making headway with the advancements made in plastics these days. Growing numbers of engineers are coming to realize its significance. Plastics are more flexible, cost-efficient, and safer. Nylon, Teflon, PEEK, Polyethylene are all available for use in plastic bearings as low-cost material. In general, plastic bearings are made of a thermoplastic alloy with a fiber matrix and solid lubricants, which reflects their superior strength and reliably low friction coefficient.
