SKF NKX 50 Z 50 mm ID Roller Bearing Needle, 70 mm OD

SKF Roller Bearing, Combined Needle Roller and Thrust Ball Bearing Type, Cylindrical Bore, 50mm ID, 71.5mm OD - NKX 50 Z

When you need the stability of needle rollers but the support capacity of a thrust ball bearing, take a spin with this dual-component combination from SKF. It's a reliable choice for applications that experience both radial and axial loads in one direction. Thanks to a low cross-sectional height of just 71.5mm, this is space-saving choice for settings where other locating bearings don't fit. For lasting performance, the thrust section has a durable stamped-steel cover to retain grease around the rolling parts, keeping them in tip-top condition for longer.

Features & Benefits

• Rollers and balls are secured in cages to reduce noise and minimise wear• High static load rating of 81.5kN (axial) and dynamic load rating of 38kN (radial), so handles demanding tasks• Reference speed of 4300r/min makes it ideal for use in medium-velocity applications

Do I need a separate inner ring for this bearing?

Needle roller bearings can be fitted directly onto a shaft, so this product typically doesn't need a separate inner ring. However, if you're using a mating surface that can't be hardened and ground, simply add SKF's IR 45X50X25 ring (209-2227) and you're good to go.
