How the 5200S model number is decoded
From the medium-duty 5200S double-row family, 5200S measures 10 mm across the bore, 30 mm over the outer ring and 14.3 mm across the faces. NTN builds the number from 52 is the double-row dimension series (medium-duty 5200S double-row family), then 00 encodes the 10 mm bore (bore code x 5), and the trailing S marks the current internal design of the family. With C 7.15 kN and C0 3.9 kN, each mm of bore carries about 0.72 kN of dynamic rating. Size selection is usually finished by checking that the C0 of 3.9 kN covers the maximum static or shock condition with the catalogue safety factor, not only the running load. Mount with the thrust against the marked face: the contact angle runs from the low shoulder of the inner ring to the high shoulder of the outer ring, and reversing it throws the capacity away.
Typical equipment & failure modes
Common applications
- bicycle and motorcycle wheel and steering positions
- small gearbox pinion shafts with helical gears
- precision instrument and encoder support shafts
- small machine-tool spindle and live-centre positions
Known failure patterns
- impact brinelling dents on the 30 deg contact path after a shaft-side hammer blow during mounting, because axial shock travels straight through the contact angle
- thermal runaway from excessive preload: the pair runs hot, grease darkens and the contact ellipse spreads until the raceways smear
- machined-cage land scoring when a high-speed spindle runs past its grease rating and the cage runs dry on its guidance surface
- contamination-induced denting — hard particles rolled into the contact ellipse become the initiation points for surface fatigue
- 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
- At 10 mm bore the rings are thin-sectioned: press force must go through the ring being fitted, never through the balls, or the first damage is already in the raceway before the machine runs.
- The double-row bearing takes reversing thrust in one envelope, but its two contact lines mean more heat than a single row at the same speed — check the thermal balance before copying a single-row speed figure.
- The 17,000 r/min speed figure assumes the catalogue lubrication state and a correctly set pair; real limits drop fast with excess grease fill or heavy preload.
- A 5200S 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 10 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 7.15/3.9 kN ratings and 0.23 kN Pu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 5200S; 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 5200S?
5200S is a double-row angular contact ball bearing to ISO 15: 10 mm bore, 30 mm outside diameter, 14.3 mm width (0.394 x 1.181 x 0.563 in). From NTN Ball and Roller Bearings CAT.No.2203E: C 7.15 kN, C0 3.9 kN and a 0.23 kN fatigue load limit Pu; the grease limiting speed is 17,000 r/min and the oil rating 22,000 r/min; mass about 50 g.
How is the 5200S designation structured?
52 is the double-row dimension series (medium-duty 5200S double-row family); 00 encodes the 10 mm bore (bore code x 5), and the trailing S marks the current internal design of the family. The 30 mm OD and 14.3 mm width follow the ISO 15 boundary-dimension plan for that series.
Which axial direction does 5200S support?
5200S is a double-row bearing working like a built-in back-to-back pair: it takes thrust in both directions plus radial load and moment (tilting) load in a single envelope.
What lubrication speeds does NTN print for 5200S?
Per NTN Ball and Roller Bearings CAT.No.2203E, the grease limiting speed is 17,000 r/min and the oil rating 22,000 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 5200S?
The 10/30/14.3 mm envelope is ISO 15 interchangeable, but internal geometry — contact angle, osculation, cage and shoulder details — is maker-specific. Re-verify C 7.15 kN / C0 3.9 kN, the speed figures, contact angle and suffix meaning against the donor catalogue before swapping on a rated drive.
