How the 213-ZZ model number is decoded
213-2Z is a filling-slot (notched-ring) deep-groove bearing in the legacy 200-series: the last two digits encode the bore: 213 carries code 13 = 65 mm (code × 5). The rings carry loading slots that allow extra balls during assembly, which is what gives the 65×120×23 mm envelope its C 60.5 kN and C0 58.5 kN ratings (Pu 2.5 kN). SKF spells the double shield 213-2Z (suffix 2Z); the shields are non-contact, retain grease and block coarse debris but are not liquid-tight. Limiting speed 4800 r/min, mass 1050 g. These bearings are built for high purely-radial loads at moderate speeds.
Typical equipment & failure modes
Common applications
- hoists and winch gear trains
- eccentric and vibratory conveyors
- legacy machinery repairs
- slew drives
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
- electrical pitting in VFD-driven motors without shaft grounding
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- Shields on 213-ZZ 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 4800 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 65×120 mm envelope, which is why 213-ZZ reaches C 60.5 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 213-ZZ, never pass the full radial load across the slot zone during mounting or the ring lip can crack.
- Shields on 213-ZZ retain grease but do not seal against water; for wet farm duty add external lip seals rather than trusting the shield.
- Mount by heating the inner ring (max 120 °C) — driving 213-ZZ home through the outer ring or balls brinells the raceways.
Frequently asked questions
What are the dimensions of 213-ZZ?
Filling-slot bearing 213-2Z measures 65×120×23 mm (2.559×4.724×0.906 in), about 1050 g.
What does the designation 213 mean?
It is the legacy 200/300 filling-slot numbering: series 200 and bore code 13 = 65 mm. Filling-slot bearings predate the 6xxx deep-groove spelling.
What is a filling-slot bearing?
The inner and outer rings each have a loading slot; when aligned, extra balls can be inserted, raising radial rating (C 60.5 kN for 213-ZZ). The slots also make the rings separable.
Can 213-ZZ take axial load?
Very little: the filling slots interrupt the raceway shoulders, so thrust towards the open slot side can unload or jam the balls. Use a standard deep-groove 6xxx bearing for combined loads.
