How the 214-ZZ model number is decoded
214-2Z is a filling-slot (notched-ring) deep-groove bearing in the legacy 200-series: the last two digits encode the bore: 214 carries code 14 = 70 mm (code × 5). The rings carry loading slots that allow extra balls during assembly, which is what gives the 70×125×24 mm envelope its C 66 kN and C0 65.5 kN ratings (Pu 2.75 kN). SKF spells the double shield 214-2Z (suffix 2Z); the shields are non-contact, retain grease and block coarse debris but are not liquid-tight. Limiting speed 4500 r/min, mass 1150 g. These bearings are built for high purely-radial loads at moderate speeds.
Typical equipment & failure modes
Common applications
- slow heavy gearboxes
- farm machinery and harvesters
- construction equipment drives
- hoists and winch gear trains
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 66/65.5 kN ratings assume radial loading — use deep-groove 6xxx where axial load matters.
- Shields on 214-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 4500 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 70×125 mm envelope, which is why 214-ZZ reaches C 66 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 214-ZZ, never pass the full radial load across the slot zone during mounting or the ring lip can crack.
- Fillet radii must clear the 214-ZZ chamfer so the 24 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
Frequently asked questions
What are the dimensions of 214-ZZ?
Filling-slot bearing 214-2Z measures 70×125×24 mm (2.756×4.921×0.945 in), about 1150 g.
What does the designation 214 mean?
It is the legacy 200/300 filling-slot numbering: series 200 and bore code 14 = 70 mm. Filling-slot bearings predate the 6xxx deep-groove spelling.
Is 214-ZZ available sealed?
Shielded executions (-2Z, listed here as 214-ZZ) exist; contact-sealed versions are generally not produced for the filling-slot family.
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 66 kN for 214-ZZ). The slots also make the rings separable.
