Cylindrical Roller Bearings SKF NU316 ECJ

The SKF NU316 ECJ cylindrical roller bearing offers high radial load-carrying capacity as a non-locating bearing with an 80 mm bore, 170 mm outer diameter and 39 mm width.

The SKF NU316 ECJ cylindrical roller bearing is a single-row radial roller bearing designed for demanding industrial applications. Thanks to the line contact between the cylindrical rollers and the raceways, this design can accommodate very heavy radial loads. The design features an optimised internal structure that ensures favourable stress distribution. As it is an open bearing without sealing rings, the lubricant can be supplied directly via the housing design.

In which installation scenarios does the NU316 ECJ cylindrical roller bearing prove its worth as a non-locating bearing?

This bearing unit is primarily used where high radial loads act on shafts with a diameter of 80 mm. As a pure idler bearing, the design compensates for thermally induced length changes in the shaft directly within the bearing. The inner ring can be removed from both sides, which facilitates the separate assembly of the inner and outer rings in confined installation spaces.

What is the function of the version with a sheet steel cage?

The sheet steel cage (designation J) guides the cylindrical rollers and keeps the component weight moderate. In conjunction with the optimised internal geometry (EC), the bearing is suitable for radial load-bearing at standard speeds. The bearings are manufactured with standard radial clearance and to a specified precision: dimensional tolerances comply with class P0 or ABEC 1, whilst running accuracy is to P6 or ABEC 3. The permissible operating temperature range is from –30 to +150 degrees Celsius.
