Lubrication-free bearings

Lubrication-free bearings, also known as self-lubricating bearings, are a type of bearing that does not require external lubrication to operate efficiently. These bearings are designed to be used in applications where external lubrication is not possible or desirable, such as in food processing equipment, medical devices, and other clean environments.

Product Description

Product Description:

Lubrication-free bearings are made from a variety of materials, including plastic, sintered metal, and composite materials. These materials are specifically chosen for their ability to self-lubricate, either through the use of embedded solid lubricants or by being designed with a porous structure that can retain and distribute lubricant over time.

The solid lubricants used in lubrication-free bearings can include materials such as graphite, molybdenum disulfide, and PTFE. These materials are embedded in the bearing material, either through a sintering process or by impregnating the material with the lubricant. The result is a bearing that can operate without the need for external lubrication, while still providing good performance and durability.

Lubrication-free bearings Advantage:

1.Low maintenance: Lubrication-free bearings do not require external lubrication, which reduces the need for maintenance and the associated costs. This can result in significant cost savings over the lifetime of the bearing.

2.Clean operation: Lubrication-free bearings do not require the use of oils or greases that can leak or contaminate surrounding areas. This makes them ideal for use in applications where cleanliness is critical, such as in food processing equipment and medical devices.

3.Wide range of applications: Lubrication-free bearings are suitable for a wide range of applications, including those where external lubrication is not possible or desirable. They are commonly used in high-temperature, high-speed, and corrosive environments.

4.Long service life: Lubrication-free bearings are designed to provide long service life, even under demanding operating conditions. They are typically made from high-quality materials that are resistant to wear and corrosion, which can help to extend their service life and reduce maintenance costs.

5.Reduced friction and noise: Lubrication-free bearings are designed to reduce friction and noise, which can improve performance and reduce wear. They are typically made with precision tolerances and advanced lubrication systems, which help to reduce wear and improve efficiency.

FAQ

What is the material of bearing steel?

Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as a high elastic limit. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most stringent steel types in all steel production. In 1976, the International Organization for Standardization ISO incorporated some common bearing steel grades into international standards, and divided bearing steel into 17 categories: fully hardened bearing steel, surface hardened bearing steel, stainless bearing steel, and high temperature bearing steel. steel number. Bearing steel is mainly used to manufacture rolling elements and rings of rolling bearings. Since the bearing should have the characteristics of long life, high precision, low calorific value, fast speed, good rigidity, low noise, and high wear resistance, the bearing steel is required to have: high hardness, uniform hardness, high elastic limit, and high contact fatigue. Atmospheric lubricant strength, necessary toughness, certain hardenability and corrosion resistance. In order to meet the above performance requirements, the uniformity of the chemical composition of the bearing steel, the content and type of non-metallic inclusions, the particle size and distribution of carbides, and decarburization are strictly required. Bearing steel generally develops in the direction of high quality, high performance and diversification. Bearing steel is divided into high carbon chromium bearing steel, carburized bearing steel, high temperature resistant bearing steel, stainless steel bearing steel and special bearing material according to characteristics and application environment.

What is a bearing?

Bearings are parts that support the shaft, used to guide the rotational movement of the shaft, and bear the load transmitted from the shaft to the frame. Bearings are widely used and demanding supporting parts and basic parts in the machinery industry. They are the supporting components of the rotating shafts or movable parts of various machines, and are also the supporting components that rely on the rolling of rolling bodies to realize the rotation of the main engine. Known as mechanical joints.

What is the difference between high temperature resistant bearings and ordinary bearings?

Compared with ordinary bearings, high temperature bearings have high temperature resistance up to 500°C or 800°C, greater bearing capacity, oxidation and corrosion resistance, high hardness and wear resistance, strong impact and bite resistance, smooth and shiny appearance, self-lubricating, low There is no lubricant for those with high speed, the load is 1.4 times that of ordinary bearings, and the average life is more than five times that of ordinary bearings. In addition to being different in performance and material, the expression of the model is also different.

The parts of the bearing are made of bearing steel and subjected to high-temperature tempering treatment, and the post code is in accordance with the regulations of JB/T2974 (the parts have been subjected to high-temperature tempering treatment, and the working temperature can reach 150C°, and the code is /SO; the sh07 parts have been subjected to high temperature After tempering treatment, the working temperature can reach 200°C, and its code is /S1; after high-temperature tempering, the working temperature can reach 250°C, and its code is /S2; after high-temperature tempering, the working temperature It can reach 300°C, and its set code is /S3; after high temperature tempering treatment, the working temperature can reach 350°c, and its set code is /S4).

2. The parts of the bearing are made of heat-resistant steel, and its postcode is in accordance with the regulations of JB/T2974 (the material is Cr4Mo4V, and its postcode is /HN; the material is Cr14Mo4, and its postcode is HN1; the material is Cr15Mo4V, and its The postcode is /HN2; the material is W18Cr4V, and the postcode is /HN3).
