What primary advantage if any does a ball bearing have over a roller bearing?
As a general rule, ball bearings are used at higher speeds and lighter loads than are roller bearings. Roller bearings perform better under shock and impact loading.
What are similarities and differences between a plain bearing and a roller bearing?
Rollers facilitate low friction at high working loads. Heavily-loaded lines run faster, smoother and are more easily adjusted compared to a plain bearing block. They can also be smaller and lighter than a ball bearing block, for the same working load, due to the increased contact between the rollers and the hub.
Do ball bearing turbos spool faster?
Ball bearing turbos offer unmatched throttle response, spooling up to 15% faster than traditional journal bearings. Ball bearings have less friction for the compressor and turbine to spin on. Thus they are faster to spool. This improved responsiveness equals better acceleration.
How much play should a ball bearing turbo have?
Generally, a new ball bearing turbo will have a *slight* amount of up/down play as well as a tiny bit of in/out play due to their thrust plate design.
What causes turbo bearings to fail?
Most failures are caused by the three ‘turbo killers’ of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.
Do I need an oil restrictor for my Turbo?
Journal Bearing Turbo An oil restrictor is generally not needed except for oil-pressure-induced leakage. The recommended oil feed for journal bearing turbochargers is -4AN or hose/tubing with an ID of approximately 0.25”.
What is a floating bearing turbo?
Fully floating bearings rotate at less than half of the speed of the shaft. A fully-floating journal bearing system for a turbocharger will use two individual journal bearings—one near the compressor wheel and the other near the turbine wheel.
What is a floating bearing?
A floating bearing arrangement is a bearing arrangement or configuration in which the bearings and the mating component(s) are able to move freely relative to each other in either the radial or axial direction.
What does a bad turbo bearing sound like?
A loud whining noise – Often, a failing turbocharger will make a loud, distinctive noise when under boost – a bit like a dentist’s drill or police siren if compressor wheel damaged. If you start to hear this noise from your engine, it’s definitely time to have it checked out!
Are Borg Warner turbos ball bearing?

What do Garrett Turbo numbers mean?
GT simply stands for “Garrett Turbo” 25 refers to the “frame size” of the turbo, based on the turbine wheel inducer (the inducer being the top of the blade). 60 refers to the compressor exducer size, in millimeters, of the compressor wheel.
How do I know what Garrett turbo I have?
Look for the identification name plate of the turbo. In the T series you can usually find it on the body of the turbo or on the inlet plate, held by 2 clinches. Although in the GT series it is usually recorded by computer on the compressor housing or with a name plate held by 2 clinches.
