If you do not have enough room for ball bearings, needle roller bearings may be the answer!
- Extremely low radial section height - thanks to thin cylindrical rollers inside the bearing, the bearing hole does not need to be much larger than the shaft.
- These are wider (longer) than ball bearings, and we carry extra wide versions of some for even higher loads.
- Needle roller bearings have a much higher load rating than ball bearings, but slightly reduced speed rating (though still 20k-40k rpm).
- Easily support motor shafts, weapon shafts, and other axles.
- Available in a variety of sizes to suit your needs.
Specifications:
Chrome steel construction, oiled for extended life and high RPM.
* Make sure you have a hard inner shaft. Very soft metals and plastics can be deformed by the needle rollers on impacts.
