During the process of tool machine, the instant large axial impact damages the bearing, resulting in isometric indentation around the bearing raceway, and then generates noise during operation.
Excessive thermal expansion of the ball screw during operation will lead to bearing failure.
If the minimum load requirements are not met, sliding can occur and generates excessive heat and noise. In addition, loose fit between bearing and rotor can also have a detrimental effect on bearing performance because of sliding.
Insulated bearing with a layer of PPS insulating resin material coating on the width and the outer ring has the characteristics such as anti-corrosion, high reliability, cost-effective and can mainly be applied to PWM controlled motor.
Proper maintenance and handling of bearings are essential, directly affecting their longevity and performance. For bearings, corrosion is an often undetected and natural enemy.
- If an impact force was applied to the bearing, certain indentations will occur and bearing noise shall be observed accordingly.
TPI bearings are well-known and widely used in bicycle industry. For example, the hubs and wheelsets of Rio 2016 Olympic championship bicycle was supplied by a Swiss high-end bicycle component manufacturer who has long term cooperation with TPI.
Characteristics of three types of cages as shown in Table 1. below...
SUJ2 is the standard bearing steel while 2A and UL represent SUJ2 treated with carbonitriding and ultra-clean process separately.
Based on years of bearing design and manufacturing experience, TPI is able to analyze the causes of bearing damage and failure. In previous technical paragraphs, effective solutions for different types of bearing failure were provided.
All ceramic ball bearing (S series) was an entirely successful solution for bike wheel hubs when TPI first issued in 2020. It, all ceramic ball bearing (S series), has both extraordinary material properties and bearing performance in our factory examination and on the field.
- Incorrect mounting method and mounting tool defect may lead to an overload force between bearing rings and rolling elements.
