Type: Needle roller bearing with inner ring, HK series (Nadella/INA). A single row of thin, long needles (D ≤5mm, L/D ≥2.5), solid outer ring, separable inner ring.

Inner ring: Supplied separately in the JR series, allows mounting when the shaft is not hardened and ground. Reduces stress on components, makes adjustment easier.

Needle rollers: Thin and long for high radial capacity in a compact space, linear load distribution.

Load capacity: High radial capacity despite compact dimensions, low axial capacity (purely radial bearings).

Speed: Moderate speeds (up to 6.000-8.000 rpm), oil lubrication essential.

Protection: Generally open, without shields, robust design for industrial environments.

Lubrication: Periodic oil lubrication, often centralised through holes in the housing.

Specifications: Maximum radial compactness, high radial capacity, separable inner ring, standard tolerances, temperature -30°C to +100°C.

Applications: Automotive engine connecting rods, compact transmission systems, gearboxes, applications where radial space is critical and load is high.

Benefits: Maximum radial compactness, high load capacity, adjustable inner ring, robustness, economy.
