GQZ TAF293830 Machined Needle Roller Bearing 29×38×30mm No Inner Ring With Outer Ring Lubrication Hole

TAF293830 is single-row machined needle roller bearing without inner ring, interchangeable with standard NK29/30. It consists of rigid machined outer ring, stamped steel cage and precision needle rollers. The shaft journal surface acts directly as inner raceway, greatly reducing radial installation space. Equipped with built-in oil hole on outer ring for periodic refueling, excellent radial load capacity and stable high-speed rotation, widely used for compact transmission assemblies with limited installation space.

1. Inner-ring-free design, adopt quenched shaft surface as rolling raceway, minimize radial space occupation for compact equipment layout
2. Dense needle roller arrangement delivers ultra-high radial load capacity under slim cross-section size
3. Integral machined outer ring with high rigidity, no deformation even installed inside light alloy housings
4. Reserved lubrication hole on outer ring supports offline refueling without disassembly, extend service cycle
5. Superfinished rollers and raceway lower friction heat, vibration and noise under continuous high-speed operation
6. Fully interchangeable with original IKO TAF293830 and INA NK29/30 for aftermarket replacement
7. Custom precision grades P0/P6/P5, stainless steel version and OEM laser marking supported
