How the N2316E model number is decoded

NTN lists N2316E on the 80×170 mm envelope, 58 mm wide: a line-contact radial bearing with the high-capacity pressed-steel cage of the E execution and a grease limiting speed of 3,300 r/min. Numbering ties N2316E to its envelope: type code N, series N2300, 80 mm bore; the 170×58 mm outline therefore swaps dimensionally with other ISO 15 bearings of the same code, though rib arrangements differ by prefix. The 58 mm width and 45.0 mm section put the N2300 series in the extra-wide (23) section; wide 22/23 variants at the same bore change OD, width and heat generation and are not drop-in swaps. Equivalent-load planning treats N2316E as a pure radial bearing: keep P below 395 kN at the required L10, and let a paired angular-contact or thrust part carry any sustained axial component. Provide axial location with an adjacent locating bearing rather than expecting the float cylindrical set to hold thrust on the 80 mm shaft.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Induction-heat the 80 mm inner ring (max 120 °C) and mount it before fitting the outer ring; the ring mass makes square guidance essential — driving through the rollers brinells the 170 mm raceway.
• Wide (22/23) and light (10/49) executions at 80 mm bore share bore but not OD/width; check the full N2300 series code before substituting, because housing and shoulder geometry will not interchange.
• The 58 mm width and abutment faces must be square to the axis; a tilted spacer concentrates load across the roller set and shows as uneven raceway polish on the 80 mm inner ring.
• Open N2316E units need application-supplied sealing and a defined lubricant schedule; film thickness is the first failure mode for line contact when viscosity drops at the 80 mm contact.

• The 395/430 kN ratings, 49 kN Pu and 5780 g mass are NTN Ball and Roller Bearings CAT.No.2203E values for N2316E (E high-capacity execution); other makes sharing the ISO 15 envelope revise internal geometry without changing the order number, so keep the 2203E reference with the specification for critical drives.
