Made of solid rings (outer and/or inner), the shaft and housing do not require any particular treatment.
Designed to withstand very high, purely radial loads, the solid ring needle bearing is offered with or without an inner ring (in this case, the shaft must have the required characteristics for a raceway).
The basic NA bearing (RNA without an inner ring) exists in several width series, 48, 49, 59 or 69.
There is also the NK light series and NKS heavy series.
IR inner rings can be used alone or with any type of needle bearing (including cages, sleeves, combined bearings, etc.).
Versions with single (...L) or double sealing (...LL) are also available on series 49.
Dimensions: from 5 to 490 mm and 3/8 to 8 inches
