How the 16048-MA model number is decoded
In the 16000-series, the last two digits encode the bore: 16048 carries code 48 = 240 mm (code × 5). The envelope is 240×360×37 mm (9.449×14.173×1.457 in) with a 60.0 mm radial section height, C 203 kN, C0 255 kN and Pu 6.3 kN. The open 16048 MA carries no shields or seals and relies on application lubrication and external sealing. The MA suffix identifies the machined brass cage execution, a separate order number from the pressed-steel version. Limiting speed 3000 r/min, catalogue mass 14000 g. A thin section saves space but leaves little margin for misalignment or shaft deflection.
Typical equipment & failure modes
Common applications
- textile and packaging machinery
- slew and indexing drives
- large industrial gearboxes
- heavy conveyor drives
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- raceway smearing under marginal lubrication at start-up
- electrical pitting in VFD-driven motors without shaft grounding
Selection pitfalls — read before you substitute
- Mount by heating the inner ring (max 120 °C) — driving 16048-MA home through the outer ring or balls brinells the raceways.
- Fillet radii must clear the 16048-MA chamfer so the 37 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- The MA suffix on 16048-MA denotes a machined brass cage: it is the choice for high speeds, marginal lubrication and shock/vibration duty, and it is temperature-tolerant where polymer cages are not — the 14000 g quoted mass includes the heavier cage.
- Open 16048-MA needs external sealing at the arrangement level; in dusty housings its life depends entirely on those external seals and the regreasing schedule.
- Plan a relubrication interval for 16048-MA; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- At 240 mm bore, C3 clearance is the safe choice when interference fits plus temperature rise consume the CN clearance; a hot tight bearing with no residual clearance fails fast.
- SKF date-codes its packaging, and greased sealed or shielded bearings carry a finite shelf life: rotate stock first-in-first-out and store boxes dry, cool and away from vibration.
- A replacement 16048 should go onto inspected seats only: SKF mounting guidance calls for clean, burr-free journals within tolerance, since a large share of early failures traces back to damaged or worn seats.
Frequently asked questions
What are the dimensions of 16048-MA?
The SKF 16048 MA measures 240 mm bore × 360 mm OD × 37 mm width (9.449 × 14.173 × 1.457 in), mass about 14000 g. It is open, with no shields or seals.
How does the bore code in 16048 work?
The final two digits of 16048 are bore code 48, multiplied by 5 to give 240 mm.
How long can a greased 16048-MA be stored?
Sealed and shielded SKF units carry a finite grease shelf life: SKF recommends first-in-first-out stock rotation and dry, cool, vibration-free storage. Open units ship with rust preventive only and are greased at assembly.
What load can 16048-MA take?
Catalogue values for 16048 MA: dynamic C 203 kN, static C0 255 kN, fatigue limit Pu 6.3 kN. Use C in life calculation and C0 for static checks at 240 mm bore.
What is the speed rating of 16048-MA?
SKF lists a 3600 r/min thermal reference speed and a 3000 r/min mechanical limiting speed for 16048 MA; real limits also depend on lubrication and fits.
