How the 215 model number is decoded
215 is a filling-slot (notched-ring) deep-groove bearing in the legacy 200-series: the last two digits encode the bore: 215 carries code 15 = 75 mm (code × 5). The rings carry loading slots that allow extra balls during assembly, which is what gives the 75×130×25 mm envelope its C 72.1 kN and C0 72 kN ratings (Pu 3 kN). The open 215 carries no shields or seals and relies on application lubrication and external sealing. Limiting speed 5300 r/min, mass 1250 g. These bearings are built for high purely-radial loads at moderate speeds.
Typical equipment & failure modes
Common applications
- slew drives
- material-handling winches
- slow heavy gearboxes
- farm machinery and harvesters
Known failure patterns
- spalling of the filling-slot edge when balls are hammered through the slot under heavy thrust loading
- dirt entering through the open slot area when external sealing is neglected
- raceway smearing under marginal lubrication at start-up
- electrical pitting in VFD-driven motors without shaft grounding
Selection pitfalls — read before you substitute
- Filling-slot bearings take heavy purely-radial load at moderate speed but little thrust; the 72.1/72 kN ratings assume radial loading — use deep-groove 6xxx where axial load matters.
- Shields on 215 retain grease but do not seal against water; for wet farm duty add external lip seals rather than trusting the shield.
- Limiting speed is just 5300 r/min: filling-slot cages and the slot geometry run cooler below that — overspeed drives cage wear and smearing.
- Filling slots let more balls be packed into the 75×130 mm envelope, which is why 215 reaches C 72.1 kN — but the slots also mean the two rings separate when the balls align with them, so handle it as a loose-clearance design.
- The slots sit at one angular position: on 215, never pass the full radial load across the slot zone during mounting or the ring lip can crack.
- Clearance suffixes follow the seal code in the designation stack (e.g. 215-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
Frequently asked questions
What are the dimensions of 215?
Filling-slot bearing 215 measures 75×130×25 mm (2.953×5.118×0.984 in), about 1250 g.
What does the designation 215 mean?
It is the legacy 200/300 filling-slot numbering: series 200 and bore code 15 = 75 mm. Filling-slot bearings predate the 6xxx deep-groove spelling.
Why use an old 200-series bearing instead of a 62xx?
For slow, heavy, purely-radial duty the extra balls give more capacity in the same bore, and the separable rings simplify assembly in blind housings; at high speed modern designs run better.
What fails on 215?
Slot-edge chipping under thrust or shock, dirt ingress in the open design and cage wear past the 5300 r/min limiting speed are the typical failure modes.
