How the 5200SCZZ model number is decoded
From the medium-duty 5200S double-row family, 5200SCZZ 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 CZZ marks the double-row SC internal design with pressed-steel shields on both sides. Catalogue dynamic rating C is 7.15 kN against C0 3.9 kN — a C0/C ratio of 0.55 that is typical of an angular-contact contact ellipse. If the duty is mainly high speed with modest thrust, the 7900-series cross-section is the lighter alternative; if thrust dominates, the 7300-series section carries more. 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
- small pump and compressor shafts with combined load
- servo and stepper motor shafts with axial preload
- bicycle and motorcycle wheel and steering positions
- small gearbox pinion shafts with helical gears
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
- loss of preload after housing-fret or shaft creep, leaving the pair loose — ball skidding, cage rattle and a falling natural frequency follow
- machined-cage land scoring when a high-speed spindle runs past its grease rating and the cage runs dry on its guidance surface
- edge loading and early spalling from housing bores that are out of round or shoulders that are too small for the ring face
- 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.
- Sealed ZZ shielded executions are grease-for-life: there is no relubrication path, so the grease life calculation replaces the relubrication plan.
- Catalogue mass and ratings belong to the open execution; shields, seals and resin cages change both the speed ceiling and the thermal behaviour of the same basic size.
- Never use a four-point or double-row bearing as a like-for-like swap for a single 5200SCZZ without re-checking axial float, heat and housing width — the kinematics differ.
- 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.
- The 7.15/3.9 kN ratings and 0.23 kN Pu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 5200SCZZ; 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 5200SCZZ?
5200SCZZ is a sealed 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 5200SCZZ 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 CZZ marks the double-row SC internal design with pressed-steel shields on both sides. The 30 mm OD and 14.3 mm width follow the ISO 15 boundary-dimension plan for that series.
Which axial direction does 5200SCZZ support?
5200SCZZ is a sealed double-row bearing: thrust in both directions, radial and moment load in one envelope, with pressed-steel shields that keep the open-bearing speed ratings.
What lubrication speeds does NTN print for 5200SCZZ?
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 5200SCZZ?
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.
