K 12X18X12 TN Needle Roller B.

Needle roller cages are needle bearings that lack an outer and inner ring. Due to their low structural height, needle roller cages enable particularly space-saving and light assemblies. Relatively long needle rollers in relation to their diameter provide rigid bearings very good load-bearing.

The needles are held together by a machined steel cage. Also available with a polyamide cage (TN). Needle rollers and cage assemblies are also produced with two rows (suffix ZW).
