The majority of angular contact bearings use phenolic type cages and these are exceptional good for a wide range of conditions and particularly for high-speed since they are outer ring located. However, there are advantages to using TYN cages in certain applications, particularly in grease lubrication. TYN is a polyamide material and this cage is designed to be ball guided. Reduced Cage Noise In certain applications cage noise can occur...
No one knows who invented the planetary gearbox, but it has been in use since the 15th century.Planetary Gearboxes is an old mechanics fundamental that is still being used for new eading innovative technology like 3D printing, and new methods of transport. Planetary gearbox consist of an internal toothed ring gear to which are set 3 planets mounted on the planet carrier engaging also with the sun gear and reduced output speed is taken t...

Key Factors of Electric Motor Bearing Design –Outline dimensions–Load size and direction–Speed requirements, constant/variable/high–Material of motor shaft and housing–Power take-off transmission form–Motor installation form–Vibration level requirements–Noise level requirements–Temperature requirements–Bearing life–Lubrication form–Maintenance–Condition mon...
From the elevator you take at work to the dump truck you see rolling by on the street, hydraulics are everywhere. But hydraulic machines are nothing without their hydraulic pumps.The hydraulic pump is the component of the hydraulic system that takes mechanical energy and converts it into fluid energy in the form of oil flow. This mechanical energy is taken from what is called the prime mover (a turning force) such as the power take-off ...
I was once a piece of iron Coming through a great deal of difficulties Smelting from iron ore Until the billet is formed Continuously quenching from lots of processes Built me an indomitable and undaunted spirit And was toughened and hardened into steel. I have thought it would be free of suffering from now on But with a big BANG I was thrown into the furnace again The burning of fire The beating of a hammer Forged me into a ring That m...
Design Variants To allow the bearings to accept the maximum number of balls, four point contact ball bearings are designed with split inner ring or with split outer ring so these bearings have two basic types, one is featured two half inner ring(QJ series), the other is featured two half outer ring(QJF series). TBB four point contact ball bearings have the contact angle of 35°. We can both provide QJ series and QJF series on request. T...
The PTC (Power Transmission and Control) Asia is an international trade fair for power transmission and control, which takes place once a year in Shanghai. Since its foundation in 1991 it has established itself as the most important trading platform of the industry and for many international companies it is the basis for their entry into the Chinese market expecting enormous growth rates during the coming years. The exhibition is divide...
NSK has developed a new ultra-high-speed bearing ideal for electric vehicles, including battery electric, hybrid, and other new energy vehicles. The new bearing enables electric motors to operate at higher speeds, improving fuel economy (reducing power consumption per unit distance), increasing maximum vehicle range, and contributing to enhanced user comfort. NSK is targeting 10 billion yen in sales by 2030. 1. Development Background Pr...
