Made from ultra-hard GCR15 steel (HRC60-65), these quality needle rollers from china pack serious durability into tiny 5.00±0.005mm diameters. Their incredible 0.0005mm roundness and Ra0.06μm mirror finish create virtually frictionless rotation, while the 9mm(+0/-0.03mm) length tolerance ensures perfect fitment every time.
As specialists in customized needle rollers, we offer sizes tailored for your most demanding applications. The quality needle rollers from china feature aerospace-level precision with 0.005mm parallelism/perpendicularity – ideal for cam followers, linear guides, and compact bearing assemblies where space is tight but performance can't be compromised. From automotive transmissions to medical devices, these miniature workhorses deliver maximum load capacity with minimum space requirements!
Why Designers Choose Them:
• Space-saving high-load design
• Ultra-precise 0.0005mm roundness
• Mirror-smooth Ra0.06μm finish
• Available in customized lengths
