Which bearing can withstand both thrust and radial?
The “load” is the force applied to a bearing. The “radial load” is the force applied perpendicular to the shaft. The “axial load” is the force applied in the same direction as the shaft. Deep groove ball bearings sustain both radial load and axial load coming from both directions at the same time.
When were the first roller bearings used in pulley blocks?

Can you replace the ball bearing wheel bearings in a 1964 VW Beetle with roller bearings?
No, the unit was set up for ball bearings. Rollers will not work. Yes you can and I just did! The races in the hub must be replaced with ones that came with new roller bearing. Inner bearing races must be removed from spindle and not used. Got the roller bearings from PartsPlace for VW in Auburn Hills, Michigan
