Difference between high-speed and low-speed bearings Many people may misunderstand it, it’s not that the rotation speed of the bearing itself, but its linear speed. Many low speed bearings can reach tens of thousands of revolutions per minute, on the other hand, for some high-speed bearings, the data of rotations per minute maybe only just a few hundred. There are also some other differences between the two. Generally, low-speed b...
When bearings are 100% inspected with all dimensions on approved drawings based on GB or ISO standard, we confirm bearings are qualified. Here we would like to share you with a case: One day we received an urgent request from our customer, that they asked us to deliver one SL bearing (full complement cylindrical roller bearing) to them in short time, reason was that the bearings delivered from their current supplier were rejected by the...
The type of machinery is different, the service conditions of the bearings will be different, and the performance requirements are also different. Generally speaking, there are more than two bearings that would be used on a shaft. In order to facilitate axial positioning, most of the bearings are used as fixed-end bearings, and the rest are used as floating-end bearings. The following table lists the choice of fixed end and floating end...
Bearing Selection Guide The types, structures, and sizes of rolling bearings are diverse. In order to make the mechanical device play the expected performance, it is very important to choose the most suitable bearing. To select a bearing, many factors need to be analyzed. The general sequence is as follows: (1) Understand the operating conditions of mechanical devices and bearings, etc. (2) Clear requirements for bearings (3) Select the...
Have you ever noticed the types of cage guidance of your bearings? Basically, there are 3 types: outer-ring-rib guidance, inner-ring-rib guidance, and rolling-element guidance. Unfortunately, big part of Chinese factories, including big brands, don’t put their eyes on cage guidance. They believe various types of cage guidance are interchangeable. You may get NU2310 with MA brass cage with outer-ring-rib guidance, even though y...
Full complement cylindrical roller bearings are capable of carrying higher radial loads than bearings that utilize a cage and roller design....
There are many types of bearing materials, among which stainless steel is probably one of the most commonly used bearing materials. Compared with ordinary bearing steel (Chrome steel GCr15/100 Cr6/SUJ2), stainless steel bearing not only have obvious advantages in material, but also much strict in process and precision control than ordinary bearing. It is more stable, has low noise and stronger anti-rust and anti-corrosion properties, it...
Full ceramic bearings have the characteristics of magnetoelectric insulation, wear resistance, corrosion resistance, oil-free self-lubrication, high temperature and cold resistance, which can be used in extremely harsh environment and special working conditions. Material ZrO2 has perfect properties such like suitable for low and high temperatures, high load capacity, corrosion resistance, nonmagnetic insultated and self-lubrication. Thu...
Apprehensions about a steel shortage in China are unfounded and the recent price increases have largely been a result of short-term market-related factors, experts said. “There is no shortage of supplies. The price surge is not an exact reflection of the current supply and demand situation,” said Wang Jing, an analyst with the Lange Steel Information Research Center. On Monday, steel product prices, tracked by the center, ro...
