How the 5200SCLLD model number is decoded
The medium-duty 5200S double-row family entry 5200SCLLD carries a 10 mm bore in a 30 mm outside diameter, 14.3 mm wide envelope. Reading the code: 52 is the double-row dimension series (medium-duty 5200S double-row family), 00 encodes the 10 mm bore (bore code x 5), and CLLD marks the SC internal design with contact rubber seals on both sides. The grease limiting speed is 15,000 r/min and no oil rating is printed for this execution. 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. Heat-mounting to 80-90 deg C is the clean route onto a 10 mm shaft; drive-fits through the balls transmit force through the contact ellipse and can brinell it.
Typical equipment & failure modes
Common applications
- high-speed router, grinder and woodworking spindles
- small pump and compressor shafts with combined load
- servo and stepper motor shafts with axial preload
- bicycle and motorcycle wheel and steering 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
- resin-cage cracking on the 7900-series sizes after hot, dry running or solvent attack on the polymer
- contamination-induced denting — hard particles rolled into the contact ellipse become the initiation points for surface fatigue
- edge loading and early spalling from housing bores that are out of round or shoulders that are too small for the ring face
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 LLD contact-seal 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.
- A single-row angular contact left loose on the shaft to "help assembly" will fret the seat: the contact angle keeps driving the ring axially under load.
- Grease rated for deep-groove motor duty is not automatically right at 15,000 r/min with preload; check the grease speed factor against the catalogue figure.
- The 7.15/3.9 kN ratings and 0.23 kN Pu here are NTN Ball and Roller Bearings CAT.No.2203E figures for 5200SCLLD; 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 5200SCLLD?
5200SCLLD 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 15,000 r/min and no oil rating is printed for this execution; mass about 50 g.
How is the 5200SCLLD 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 CLLD marks the SC internal design with contact rubber seals 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 5200SCLLD support?
5200SCLLD is a sealed double-row bearing: thrust in both directions, radial and moment load in one envelope, with contact rubber seals (grease-lubricated, no oil speed rating).
What lubrication speeds does NTN print for 5200SCLLD?
Per NTN Ball and Roller Bearings CAT.No.2203E, the grease limiting speed is 15,000 r/min and no oil rating is printed for this execution. 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 5200SCLLD?
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.
