NJ 317 ECM/C4VA301 Cylindrical Roller Bearing 85x180x41 Mm For Railway Vehicle Traction Motors

NJ 317 ECM/C4VA301 Cylindrical Roller Bearing 85x180x41 mm For Railway Vehicle Traction Motors

Cylindrical Roller Bearing, NJ317ECM/C4VA301, 85x180x41 mm, Brass Cage, Single Row, No Seal, Inner Ring-Both Side Separable; No Snap Ring, Relubricatable, C4.

 

The NJ317ECM/C4VA301 is a single-row cylindrical bearing with NJ design. The outer ring has two rigid ribs, while the inner ring has one rigid rib. As a result, NJ bearings can support radial forces as well as axial forces in a single direction. This bearing type is used as a support bearing. Support bearings allow axial displacement of the shaft relative to the housing in one direction. The shaft is located axially in the other direction. NJ bearings can also be used as locating bearings by combining them with HJ angle rings (available separately). Locating bearings are used to locate a shaft axially in both directions.

 

EC: Optimized Internal Design Incorporating More And/Or Larger Rollers And With Modified Roller/End Flange Contact.

M: Two-Piece Machined Brass Cage, Roller Centered

C4: Bearing Internal Clearance Greater Than C3.
