How the 6092-MB model number is decoded
In the 6000-series, the last two digits encode the bore: 6092 carries code 92 = 460 mm (code × 5). The envelope is 460×680×100 mm (18.11×26.772×3.937 in) with a 110.0 mm radial section height, C 582 kN, C0 1060 kN and Pu 19 kN. The open 6092 MB carries no shields or seals and relies on application lubrication and external sealing. The MB suffix identifies the machined brass cage execution, a separate order number from the pressed-steel version. Limiting speed 1500 r/min, catalogue mass 120000 g.
Typical equipment & failure modes
Common applications
- lay shafts and idler shafts
- textile and packaging machinery
- slew and indexing drives
- large industrial gearboxes
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- false brinelling from vibration while the shaft stands idle
- fretting corrosion on a creeping shaft or housing seat
Selection pitfalls — read before you substitute
- At 460 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.
- At 460 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.
- The MB suffix on 6092-MB 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 120000 g quoted mass includes the heavier cage.
- Open 6092-MB 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 6092-MB; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- At 460 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.
Frequently asked questions
What are the dimensions of 6092-MB?
The SKF 6092 MB measures 460 mm bore × 680 mm OD × 100 mm width (18.11 × 26.772 × 3.937 in), mass about 120000 g. It is open, with no shields or seals.
How does the bore code in 6092 work?
The final two digits of 6092 are bore code 92, multiplied by 5 to give 460 mm.
What is the speed rating of 6092-MB?
SKF lists a 1800 r/min thermal reference speed and a 1500 r/min mechanical limiting speed for 6092 MB; real limits also depend on lubrication and fits.
What is the difference between 6092-MB and a same-bore 62-series bearing?
Section height differs: 6092-MB has a 110 mm radial section and C 582 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
