Metric Needle Roller Bearing Inner Ring With Built Tough Hardened Steel Raceway 30mm Bore 35mm OD Flat Face 30 Wide Din Compliant Workhorse Grade Part For Reliable Drive Application

Single needle roller inner ring for truck transmission builds
✔️ 30mm bore 30mm width 35mm OD DIN 620 hardened steel build

This single inner ring provides a hardened raceway where your shaft cannot do the job. You will pair it with separate needle roller bearings and cage assemblies for pump drives, tractor gearboxes, or compressor housings. The precision grind reduces rotational friction so your equipment runs smoother under heavy radial loads.

✅ 30mm inner diameter fits standard shaft sizes
✅ 35mm outer diameter stays stable under torque stress
✅ 30mm thick body handles continuous axial pressure
✅ Flat face design mates cleanly with mating hardware

💡 How does a precision needle roller inner ring improve long term driveline reliability?
A dedicated steel sleeve replaces worn shaft surfaces and keeps your rollers tracking straight. This handy component saves you from swapping entire gearboxes when you spot early score marks on your old metal.
- Measured DIN 620 geometry fits factory housing bores without extra grinding
- Toughened raceway surface takes repeated sliding contact without wearing through
- Direct roller guidance cuts down unscheduled downtime on construction rigs and pick-up trucks
