How the 33895-33822-NTN model number is decoded
NTN supplies this 2.125 in (53.975 mm) shaft position as 4T-33895/33822: cone 33895, cup 33822, profiled rollers and a pressed-steel cage, rated 119 kN basic dynamic and 139 kN static. Cone and cup of 4T-33895/33822 are separately stocked parts: a worn 33822 cup can be replaced against the existing 33895 cone, provided the new cup carries the identical reference — pairing across references changes the 27.783 mm assembled width and the rating. Imperial cross-check for the drawing: 53.975×95.25×27.783 mm converts to 2.125 × 3.75 × 1.094 in; the ABMA envelope swaps with like-numbered inch parts but the 119/139 kN ratings are NTN-specific. The printed 119/139 kN ratings belong to the assembled 33895+33822 pair; a sibling row using the same cone with a different cup carries its own rating row because the raceway track shifts with the cup. After bedding-in, re-check the end play of the adjusted 4T-33895/33822 pair — initial seating of the ring faces relaxes the setting slightly.
Typical equipment & failure modes
Common applications
- machine-tool headstocks on inch spindles
- pump and blower drive shafts with combined load
- truck and trailer axle hubs on inch-dimensioned axles
- agricultural tractor transmission and PTO shafts
Known failure patterns
- cone-rib and roller large-end smearing when the adjusted pair runs with preload but starved lubricant film
- flaking on one cone only when a bent shaft loads the O/X pair unevenly
- cup creep and housing fretting when the cup seat is cut too loose for the rotating load
- cage fatigue when the pair runs continuously near the grease limiting speed without oil cooling
- water-induced pitting when the open bearing sees washdown without external seals
Selection pitfalls — read before you substitute
- Hub and pinion positions of this 53.975 mm class are adjusted in pairs; verify end play against the axle or gearbox drawing and re-torque after bedding-in instead of trusting the first setting on 4T-33895/33822.
- The pure-numeric inch family at 53.975 mm bore (95.25×27.783 mm assembled) is one of several inch families sharing similar bores; cross-series swaps change OD, T and contact angle, so match the full 33895/33822 reference at purchase.
- An unloaded 4T-33895/33822 near 3,900 r/min lets rollers skid and smear the cone rib; spring-preload lightly loaded high-speed pairs.
- Fit selection follows the rotating ring: a rotating cone on a 53.975 mm shaft takes a k5/m5 seat, and a rotating cup reverses the logic — decide from the load diagram, not from habit.
- Quote the full 33895/33822 pair at ordering: the 33895 cone also ships against sibling cups, and a cup from another reference changes the 27.783 mm assembled width and the rating.
- The 119/139 kN ratings here are NTN Ball and Roller Bearings CAT.No.2203E figures for 4T-33895/33822; internal geometry legitimately differs between inch-series makers, so re-verify ratings, adjustment and the exact cone/cup references before substituting another brand on a rated drive.
Frequently asked questions
What are the dimensions and catalogue ratings of NTN 4T-33895/33822?
4T-33895/33822 is an inch-series single-row tapered roller bearing to the ABMA boundary plan: 53.975 mm bore (2.125 in), 95.25 mm outside diameter and 27.783 mm assembled width T (3.75 × 1.094 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 119 kN, C0 139 kN, grease limiting speed 3,900 r/min, oil speed 5,200 r/min, mass about 823 g. It is an open, separable cone/cup set with a pressed-steel cage.
Are the cone and cup of 4T-33895/33822 interchangeable separately?
Yes — ABMA inch parts are individually interchangeable: the 33895 cone or the 33822 cup can be replaced by an identical reference from NTN or another ABMA-dimensioned maker. Pairing the cone with a different cup reference is a different catalogue row: OD, assembled T and the 119/139 kN ratings change with the cup.
What is the difference between 4T-33895/33822 and a metric ISO 355 tapered bearing?
4T-33895/33822 follows the ABMA inch boundary plan with cone/cup references; ISO 355 bearings use metric dimension-series numbers (302, 322, …). Even where a metric size looks close to 53.975×95.25×27.783 mm, the envelopes and contact angles differ — the two systems are not drop-in interchangeable; check every boundary value before substituting.
What does the 4T prefix on 4T-33895/33822 mean?
4T is NTN's tapered roller bearing quality mark, stamped on cone and cup in the factory. It identifies NTN's 4T programme and is not a dimension or variant code, so interchange lists quote the bare 33895/33822 references; the 4T spelling is retained among this page's search aliases.
Why does 4T-33895/33822 list two speeds, 3,900 and 5,200 r/min?
The lower figure, 3,900 r/min, is the grease-lubricated limiting speed — the mechanical ceiling for the cage, rollers and cone-rib contact. With oil lubrication NTN rates 4T-33895/33822 at 5,200 r/min because oil removes rib-contact heat better. Real limits still depend on pair adjustment, oil flow and cooling.
