FAG Bearings Applied Materials Introduction

FAG Bearings Applied Materials Introduction

1.FAG bearing steel Features:

Steel production, clean and high mass fraction of the elements appropriate (according to experimental data, when the oxygen content of bearing steel 30 × 10 ^ 6, the 6 th of 15 × 10, 10 × 10 ^ 6 and 5 6 th than life when the bearing is 1 × 10: 4:14: 30). In the bearing properly installed, a small load, lubrication good conditions, FAG part bearing can reach infinite life.

2. Press the operating mode selection of materials

(1) General class of small size: the use of high-carbon chromium bearing steel (Chinese steel GCr15, German steel DIN100Cr6). This steel has high surface hardness (Rockwell hardness value of HRC58 ~ HRC65), wear resistance, and low price.

(2) large size, heavy load: carburizing bearing steel. This steel surface hardness and high carbon chromium bearing steel similar, but less hard-core, high toughness, when the bearing is subjected to a large load or impact load, high surface hardness to meet the wear requirements, while the core high tenacity can play a buffer effect, so as not to impact load bearing by fragmentation.

(3) high-temperature bearings: In addition to plastic cage outside the bearing, the maximum operating temperature can reach 150 ℃, higher operating temperature is represented by a suffix, respectively S1--200 ℃, S2--250 ℃, S3--300 ℃, S4--350 ℃.

(4) Other: stainless steel bearings (eg S60xx.W203B); spindle bearings (angular contact ball bearing) of ceramic material, such as HCB70xx, HCS70xx, high temperature, low temperature, wear and corrosion resistance, light weight, high-speed centrifugal force Small, absolutely

Edge advantages.

3.FAG bearing cage material required performance:

Dimensional stability, good mechanical strength, in addition, we also need good processability. Depending on the application, there are requirements for impact resistance, heat resistance, corrosion resistance.

4.FAG bearing cage material:

Stamping cage materials, the use of low carbon steel. Depending on the application, but also the use of brass, stainless steel plate. Cutting cage materials, the use of high strength brass, carbon steel, in addition, also the use of synthetic resin.
