SKF Needle Bearing with Inner Ring, NA 4900.2RS 10x22x14

Needle bearings of types NA 49, NA 69, NKI, and NKIS. Needle bearings with raceways made of rolling bearing steel are low-profile bearings with relatively high load capacity. Bearings with inner rings are suitable for applications where hardening and grinding of the shaft is not possible. They allow axial displacements between the shaft and housing only within certain limits. The bearings with flanges on the outer ring are primarily designed as single-row bearings. In all cases, the outer ring, needle rollers, and cage form a self-contained unit. Bearings of the NA 49 series are also available with sealing rings (suffix 2RS). This effectively protects the bearings against the ingress of contaminants and the escape of grease. The inner ring of the sealed bearings is made 1 mm wider and features a lubrication hole. This ensures that the bearings remain effectively sealed even with small axial displacements of the shaft relative to the housing.

Main dimensions: ISO 15:2011 / DIN 620:2000 / ISO 1206:2001 / DIN 617:1993 for bearings of series (R)NA 48, (R)NA 49, and (R)NA 69

Prefix:

NKI / NKIS Needle bearings with flanges on the outer ring, with inner ring

Suffix:
2RS Steel sheet reinforced contact seals made of acrylonitrile-butadiene rubber (NBR) on both sides
TN Glass fiber reinforced cage made of polyamide 66.
