Shell Needle Roller Bearing with 1/4 in I.D. and 7/16 in O.D., caged design and chromium molybdenum steel construction deliver compact high-load performance, smooth operation at elevated speeds, and long service life

Shell Needle Roller BA47ZOH, Inch size, 1/4 ID
✔️ 1/4 in ID × 7/16 in OD, 0.438 in width, caged, open enclosure

This shell needle roller bearing is a compact, open-bearing unit with a centered cage that keeps rolling elements evenly spaced. It’s typically used in small gearboxes, CNC spindles, linear slides, and other confined-space applications where high radial support at modest speeds is needed.

✅ ID 1/4 in (6.35 mm); OD 7/16 in (11.11 mm); width 0.438 in (11.13 mm); cage: caged
✅ Material: chromium molybdenum steel; dynamic load 2650 N; static 2310 N
✅ Max speed: up to 55000 rpm; open enclosure
✅ Series: BA-Z Inch Series; type: caged shell

💡 What is a shell needle roller bearing used for in compact machinery?
Small, handy bearings for high radial loads in tight spaces.
- Supports high-speed shafts in gearboxes, spindles, and conveyors
- Reduces friction with a tight cage arrangement
- Ideal in open housing where space is limited and RPM runs high
