Shanghai yumicro bearing welcomes the 19th National Congress of the Communist Party of China

At present, there are four kinds of common bearing materials, such as bearing materials of 420 kinds, silicon nitride steel, silicon carbide, and so on.


The performance of each bearing material is as follows:

Carbon steel: large number base, can meet the most basic bearing requirements!

Bearing steel: high precision, speed, noise, runout, etc.

Stainless steel 420: on the premise of accuracy requirements, at the same time, there are some requirements for anti rust, the relative corrosion resistance will be higher. The hardness is slightly lower than that of 440C.

Stainless steel 440C: on the premise of accuracy requirements, there are some requirements for anti rust. The relative corrosion resistance will be a little lower. The hardness is slightly higher than that of 440C.

Stainless steel 304: waterproof, anti weak acid and alkali.

Stainless steel 316: anti strong acid and alkali, non magnetic, food grade bearing.

All ceramic bearing: high temperature corrosion resistant, antimagnetic, electric insulation and vacuum.

Zirconia (ZrO2): high temperature below 270 ℃.

Silicon nitride (Si3N4): high temperature below 700 ℃.

Silicon carbide (SIC): high temperature below 1200 ℃.

Alumina (Al2O3): used as analytical reagent, dehydration of organic solvent, adsorbent, organic reaction catalyst, abrasive, polishing agent, raw material for smelting aluminum, refractory.

Due to different customers, different products and different use environment, the material of bearing is also different. However, the targeted bearing processing materials can only solve most of the problems, often can not solve some specific problems in all aspects.

Some time ago, Yu micro bearing encountered a customer in Chengdu, and the problems were as follows:

Service environment: mechanical rotation, bearing outer ring and glass contact, used to transport glass.

Dimension requirements: inner diameter: 6mm, outer diameter: 18mm, thickness: 5mm

Performance requirements: when the bearing is transferred to seed, the load is about 60-70kg. When the glass is transmitted through the bearing, it should be as quiet as possible.

According to the above requirements, Yuwei's analysis is as follows:

One: the bearing is mechanically rotating

Second: there must be a sound when the glass contacts the bearing

Third: bearing size is non-standard

In addition, according to the customer's questions, the corresponding analysis and solutions are given

1. The rubber coating part is easy to fall off? This is the problem of the combination of bearing processing technology and rubber coating process.

2. Rubber coated material is easy to lose? This is the problem of material selection between coating material and coating size.

3. When the glass passes on the bearing, the sound is too loud? This is the hardness problem of PU material.

According to the authoritative experience of Shanghai Yuwei Bearing Co., Ltd. in the industry, as well as the feedback information in the cooperation with various customers, to solve the above problems, as long as the outer ring of the bearing is coated with glue!

First of all, standard bearings: 686zz (6 * 13 * 5) or 696zz (6 * 15 * 5) can be selected. Considering the comprehensive use of bearings, 686zz can be preferred, so that the size of rubber coating will be thicker. Secondly, the materials of the outer ring are generally divided into POM and PU. Considering the hardness of the glue and the contact between the glue and glass, PU material can be preferred. However, different PU materials have different hardness points. Customer samples, as well as the information feedback to us, together with the customer information we had before, in view of the above problems, Yuwei bearing colleagues easily found the breakthrough point.
