How the 7016-NTN model number is decoded
7016 is the 80 mm bore member of NTN's standard-section 7000 single-row family, with a 125 mm outside diameter and 22 mm section width. NTN builds the number from 70 is the single-row dimension series (standard-section 7000 single-row family), then 16 encodes the 80 mm bore (bore code x 5); with no letter after the digits it is the standard 30 deg contact-angle execution — the 40 deg version carries a B. With C 59 kN and C0 50.5 kN, each mm of bore carries about 0.74 kN of dynamic rating. For a 80 mm shaft with combined load, the practical shortlist is this series, its 7300-series heavier section, and — where thrust reverses — a back-to-back pair rather than a single row. Heat-mounting to 80-90 deg C is the clean route onto a 80 mm shaft; drive-fits through the balls transmit force through the contact ellipse and can brinell it.
Typical equipment & failure modes
Common applications
- crane and hoist gearbox shafts
- paper-machine roll and calendar drives
- extruder and mixer gearbox output shafts
- mining conveyor head-shaft positions
Known failure patterns
- false brinelling on the raceway contact ellipses when a preloaded spindle sits vibrating at standstill — visible as evenly spaced flute-like wear at ball pitch
- thermal runaway from excessive preload: the pair runs hot, grease darkens and the contact ellipse spreads until the raceways smear
- pressed-steel cage pocket wear and rivet loosening after repeated ball skid at light load and high speed
- lubricant starvation scoring at the ball/raceway contact when grease volume or relubrication interval is guessed instead of calculated
- flaking that starts at the raceway shoulder on the thrust-loaded side when axial load repeatedly exceeds the design share
Selection pitfalls — read before you substitute
- Bearings of 80 mm bore arrive heavy enough that handling damage (dents from slings, tilting on the shaft) is a real failure precursor — use proper lifting and heating kit.
- The standard 30 deg bearing and its B (40 deg) sibling share the envelope; picking between them is a load-direction decision, not a quality upgrade.
- Substituting the B (40 deg) execution for the standard 30 deg bearing changes the axial/radial load split — the shaft position and the mating bearing see different forces even though the envelope is identical.
- A 7016 mounted the wrong way round still turns smoothly by hand; the failure shows up weeks later as raceway flaking on the unloaded-looking side.
- On a 80 mm shaft, an interference fit eats internal clearance; skipping the clearance/preload recalculation is the classic cause of a new bearing running 20 deg C hotter than the drawing suggests.
- The 59/50.5 kN ratings and 3.5 kN Pu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 7016; internal geometry legitimately differs between manufacturers, so re-verify ratings, contact angle and suffix before substituting another make on a rated drive.
Frequently asked questions
What are the dimensions and catalogue ratings of NTN 7016?
7016 is a single-row angular contact ball bearing to ISO 15: 80 mm bore, 125 mm outside diameter, 22 mm width (3.15 x 4.921 x 0.866 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 59 kN, C0 50.5 kN and a 3.5 kN fatigue load limit Pu; the grease limiting speed is 5,500 r/min and the oil rating 7,300 r/min; mass about 994 g.
How is the 7016 designation structured?
70 is the single-row dimension series (standard-section 7000 single-row family); 16 encodes the 80 mm bore (bore code x 5); with no letter after the digits it is the standard 30 deg contact-angle execution — the 40 deg version carries a B. The 125 mm OD and 22 mm width follow the ISO 15 boundary-dimension plan for that series.
Which axial direction does 7016 support?
One 7016 alone takes thrust in one direction only, along its 30 deg contact angle; reversing thrust calls for a second bearing or a factory-matched DB/DF/DT pair (the catalogue right-hand columns list the paired ratings). Radial load is always carried as a combined load through the angled contact.
What lubrication speeds does NTN print for 7016?
Per NTN Ball and Roller Bearings CAT.No.2203E, the grease limiting speed is 5,500 r/min and the oil rating 7,300 r/min. These are catalogue ceilings for a correctly mounted bearing with the stated lubricant; preload, fill quantity, ambient heat and paired arrangements all move the real limit.
What should be checked before substituting another make for 7016?
The 80/125/22 mm envelope is ISO 15 interchangeable, but internal geometry — contact angle, osculation, cage and shoulder details — is maker-specific. Re-verify C 59 kN / C0 50.5 kN, the speed figures, contact angle and suffix meaning against the donor catalogue before swapping on a rated drive.
