How the 219 model number is decoded
219 is a filling-slot (notched-ring) deep-groove bearing in the legacy 200-series: the last two digits encode the bore: 219 carries code 19 = 95 mm (code × 5). The rings carry loading slots that allow extra balls during assembly, which is what gives the 95×170×32 mm envelope its C 121 kN and C0 122 kN ratings (Pu 4.5 kN). The open 219 carries no shields or seals and relies on application lubrication and external sealing. Limiting speed 4000 r/min, mass 2700 g. These bearings are built for high purely-radial loads at moderate speeds.
Typical equipment & failure modes
Common applications
- construction equipment drives
- hoists and winch gear trains
- eccentric and vibratory conveyors
- legacy machinery repairs
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
- brinelling from static overload or hammer blows during mounting
- false brinelling from vibration while the shaft stands idle
Selection pitfalls — read before you substitute
- Filling-slot bearings take heavy purely-radial load at moderate speed but little thrust; the 121/122 kN ratings assume radial loading — use deep-groove 6xxx where axial load matters.
- Shields on 219 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 4000 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 95×170 mm envelope, which is why 219 reaches C 121 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 219, never pass the full radial load across the slot zone during mounting or the ring lip can crack.
- Mount by heating the inner ring (max 120 °C) — driving 219 home through the outer ring or balls brinells the raceways.
Frequently asked questions
What are the dimensions of 219?
Filling-slot bearing 219 measures 95×170×32 mm (3.74×6.693×1.26 in), about 2700 g.
What does the designation 219 mean?
It is the legacy 200/300 filling-slot numbering: series 200 and bore code 19 = 95 mm. Filling-slot bearings predate the 6xxx deep-groove spelling.
Is 219 available sealed?
Shielded executions (-2Z, listed here as 219-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 121 kN for 219). The slots also make the rings separable.
