Product Description

A lock sleeve is a mechanical device used to secure or lock two components together. It consists of a sleeve or collar that is typically made of metal and is placed over a shaft or pin. The sleeve has a set of internal grooves or teeth that mesh with corresponding external grooves or teeth on the mating component.To use a lock sleeve, the sleeve is placed over the shaft or pin and rotated until the internal teeth engage with the external teeth of the mating component. This locks the two components together, preventing them from moving or separating.

Lock sleeves are commonly used in applications where high torque or vibration is present, such as in automotive engines or industrial machinery. They provide a secure, reliable, and easy-to-use method of locking components together without the need for bolts, screws, or other fasteners.

Lock sleeves come in various sizes and designs to accommodate different shaft or pin diameters and different locking requirements. Some lock sleeves are designed to be reusable, while others are designed for one-time use only.

Lock sleeves advantages :

1.High reliability: Lock sleeves provide a highly reliable and secure locking mechanism that can withstand high torque, vibration, and other stresses.

2.Easy installation: Lock sleeves are easy to install and require no special tools or skills. Simply slide the sleeve onto the shaft or pin and rotate it into place.

3..Minimal space requirements: Lock sleeves have a low profile and minimal space requirements, making them ideal for use in tight spaces or where access is limited.

4.Reduced weight: Lock sleeves can often replace heavier and more complex locking mechanisms, resulting in a reduction in weight and overall system complexity.

5.Cost-effective: Lock sleeves are often more cost-effective than other methods of securing components together, as they require fewer components and are easier to install.

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).
