What are the materials of the bearing housing, the specifications of the bearing housing and the mat

There are two main types of bearing seals: contact seals and non-contact seals.

1. Contact sealing refers to the physical contact between the seal and the bearing.

2. Non-contact sealing means that there is no physical contact between the seal and the bearing.

There are both forging and casting, mainly casting, and then machining. However, the forging precision is high and the comprehensive performance is superior. The bearing seat is mainly made of cast iron, 16MN is its main alloying element is MN, occupy, and other W cr V, etc., which play a wear-resistant role, and has high hardness and high temperature resistance.

The bearing housing is cast, and the commonly used ones are iron castings. 16mn represents 16% manganese steel content, which plays a wear-resistant role and can also withstand temperatures of about 200 degrees. "

Basically correct. It's just 16 parts per thousandIf 16% still dares to use it?

16MN is its main alloying element is MN, which accounts for iron castings

Bearing seats are available in cast iron, cast steel, stainless steel, etc.

Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage, strictly speaking, it is composed of six parts: outer ring, inner ring, rolling element, cage, seal and lubricating oil. It mainly has an outer ring, an inner ring, and a rolling element, which can be defined as a rolling bearing. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

This depends on the specific drawings to know.

The bearing size specification comparison table is a **, which records the types of different bearings, inner diameter (mm), outer diameter (mm), width (mm), grease lubrication speed (r min), oil lubrication speed (r min), weight (kg) ......

1) Mounted outer spherical bearings, also known as bearing units (SKF's term). When there is no bearing, it is called an outer spherical bearing seat. The outer spherical bearing housing is divided into 200 series according to the series of bearings. 300 series. XOO series.

2) The outer spherical bearing seat is divided into vertical seat (P seat), square seat (F seat), diamond seat (FL seat), round seat (C seat), boss round seat (FC seat), boss square seat (FS seat), dark hole seat (PA seat), hanging seat (FA seat) according to the shape.

The fundamental code of the housing

Specification housings have a specific base designation, usually with three, four or five numbers, or a combination of letters and numbers. The first number or the first letter or letter fit indicates the housing type; The first two digits determine the ISO size series; The first digit represents the width or height series (size b, t, or h), and the second digit represents the diameter series (size d). The last two digits of the base part number are the size code of the housing; Multiply by 5 to get the inner diameter in millimeters.

The bearing is made of steel, and the bearing is a component that fixes and reduces the friction coefficient of the load during the mechanical rotation process. Bearings play an important role in modern machinery, reducing the coefficient of friction during power transmission and keeping the shaft center fixed. The materials used to manufacture the bearings are, chromium steel, chromium-molybdenum steel, nickel-chromium-molybdenum steel, which is carbonized and quenched to make the steel have a hardened layer from the surface to the appropriate depth.

There are four bearing test methods: friction and wear test, test bench test, laboratory simulation test, and actual working condition operation test.

The <> bearing seat has the characteristics of compact structure, sensitive rotation and convenient maintenance. Where there is a bearing, there must be a support point, the inner support point of the bearing is the shaft, and the external support is the bearing seat that is often said. The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

Bearing housings are available in cast iron, cast steel, and stainless steel.

1. Cast iron is economical and cheap, but not durable.

2. The durability of cast steel is high and high. Where the cast steel bearing seat should not be used, the cast steel bearing seat should be used, and when there is a problem, it is possible to carry other components.

3. Stainless steel is used in corroded places.

Slewing plate bearing housing is a kind of large and extra-large bearing housing that can accept comprehensive load and special structure, which has the characteristics of compact structure, sensitive rotation and convenient device maintenance. It is divided into split bearing housings, sliding bearing housings, rolling bearing housings, bearing housings with flanges, outer spherical bearing housings, etc.

The important construction methods of the slewing table bearing seat are: four-point contact ball slewing table bearing seat, double row angular contact thrust ball slewing table bearing seat, interspersed cylindrical roller slewing table bearing seat, interspersed tapered roller slewing table bearing seat, and three rows of cylindrical roller matching slewing table bearing seats.

Slewing bearing seats are widely used in large-scale rotary installations of lifting and transportation machinery, mining machinery, construction machinery, port machinery, ship machinery and high-precision radar.
