Doors And Windows Pulley Bearing

Category Doors And Windows Pulley Bearing

Product Description

Product Description:

Doors and windows pulley bearings, also known as sliding door bearings or window pulley bearings, are a type of bearing that is designed to support the weight of a sliding door or window while allowing it to move smoothly and easily along its track. They are typically made from high-quality materials such as stainless steel or nylon, which provide durability and resistance to wear and corrosion.

The bearing consists of a pulley wheel that is mounted on a shaft, which is supported by the bearing housing. The wheel is typically made from a smooth and hard material, such as nylon or stainless steel, that allows it to roll easily along the track. The bearing housing is designed to hold the wheel securely in place and protect it from external contaminants, such as dirt and dust.

Doors and windows pulley bearings are commonly used in residential and commercial buildings, where they are installed in sliding doors, windows, and other sliding fixtures. They are designed to provide smooth and easy operation of sliding doors and windows, which improves the overall functionality and convenience of the fixture.

One of the key advantages of doors and windows pulley bearings is their ability to provide reliable and long-lasting performance. They are designed to withstand the weight and pressure of sliding doors and windows, while also resisting wear and corrosion. Additionally, they are easy to install and require minimal maintenance, which makes them a popular choice for residential and commercial applications.

Doors And Windows Pulley Bearing Advantage:

smooth and easy operation of sliding doors and windows. This improves the overall functionality and convenience of the fixture.

1.Low friction: The use of high-quality materials, such as stainless steel or nylon, reduces friction and wear, which improves the performance and durability of the bearing.

2.Resistance to wear and corrosion: Doors and windows pulley bearings are designed to withstand the weight and pressure of sliding doors and windows, while also resisting wear and corrosion. This ensures reliable and long-lasting performance.

3.Easy installation: These bearings are easy to install and require minimal maintenance, which makes them a popular choice for residential and commercial applications.

4.Quiet operation: The smooth and low-friction operation of doors and windows pulley bearings results in quiet operation, which enhances the comfort and convenience of the fixture.

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).
