Needle Roller Bearing

Needle Rollers for Tight Radial Space

Roller assemblies, inner rings, combination units

With the housing bore fixed and no room for a ball bearing cross section, needle rollers deliver high radial capacity in a thin envelope. What we carry includes combination needle units like the SKF NKX-45 at 45x58x32 mm with thrust capability built in, heavy-duty cylindrical needle assemblies with matched inner rings up to 8 in bore, and hardened inner rings sold on their own for shafts that were never ground to serve as a raceway. That inner ring is easy to overlook: if the shaft surface is scored, replacing only the roller set will not hold up. Send shaft diameter, housing bore, and width. Related rolling parts appear as cam followers and yoke rollers.
