The RNAO60x78x40-ZW-ASR1-XL is a Light Duty Open Type, Double Row Machined Needle Roller Bearing. The Outer Ring includes a Lubrication Groove and Lubrication Hole. This Bearing has no Inner Ring, meaning the Needle Rollers are mounted directly onto the shaft. As such, the Bearing has better running accuracy as it isn't affected by assembling an Inner Ring with the shaft. In caged Needle Roller Bearings like this one, the Needles are precisely guided by the Cage to achieve ideal load distribution and the Cage is separable from the Outer Ring. These Bearings are designed for high load carrying capacity in radially compact arrangements and are used in most general purpose applications. The bearing dimensions are 60X78X40mm.

The IKO equivalent is RNAFW607840.
