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.
- Incorrect mounting method and mounting tool defect may lead to an overload force between bearing rings and rolling elements.
Most customers would like to know the expected rigidity and bearing life before finally choosing TPI bearings. For such circumstances, TPI provides a unique application to evaluate customer' s needs.
1. Temperature Rise Test
Bearing Arrangement：DTBT (<< >>)
Rotating Speed：10000 RPM
Result：TPI bearings had lower temperature rise rather than the other competitors.
Bearing Arrangement：DBT/DB (<>> / <>)
Rotating Speed：5000 RPM
Phenomenon：Noise was found at 4000RPM during running-in test.
Spindle Type：Spindle of honing machine
Bearing Arrangement：DB/DB (<> / <>)
Rotating Speed：6000 RPM
Phenomenon：Temp. rise became over high during running-in test in factory.
- Solid contaminants can be introduced into a bearing via the seals or lubricant.
