China Factory Hot Sell RNA6/38 Solid Collar Needle Roller Bearing Without Inner Ring

RNA bearings are solid collar needle roller bearings featuring compact structure, small radial size, and large load carrying capacity. Ideal for applications with limited radial space, RNA bearings are widely used in situations where the shaft or housing has swinging motion.

• Without inner ring
• Solid collar design
• Machined ring construction
• High quality materials
• Rich stock availability
• OEM acceptable

Gear pumps, sheaves, automotive transmissions, two-cycle engines, automotive gearboxes, and other industrial applications requiring compact radial space solutions.

RNA bearings typically withstand radial loads only, not axial loads. When axial loads are present, they should be used in combination with other bearings. The shaft journal surface fitted with RNA bearings acts directly as the rolling surface, requiring surface hardness ≥ HRC60 and surface roughness ≤ 0.63μm.
