How the 60-630 model number is decoded
In the large-bore 6000-series, the bore is written directly after the slash as 630 mm (large thin-section bores use the slash spelling instead of the two-digit code). The envelope is 630×920×128 mm (24.803×36.22×5.039 in) with a 145.0 mm radial section height, C 819 kN, C0 1760 kN and Pu 27 kN. The open 60/630 carries no shields or seals and relies on application lubrication and external sealing. Limiting speed 1000 r/min, catalogue mass 285000 g.
Typical equipment & failure modes
Common applications
- robotics and automation joints
- lay shafts and idler shafts
- textile and packaging machinery
- slew and indexing 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
- At 630 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.
- Assign interference to the rotating ring: on a conventional shaft-mounted 630 mm position the inner ring rotates, so use a k5/m6 shaft seat with an H7 housing — reverse the logic if the outer ring rotates.
- Open 60-630 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 60-630; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Mount by heating the inner ring (max 120 °C) — driving 60-630 home through the outer ring or balls brinells the raceways.
- The fatigue load limit is 27 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
Frequently asked questions
What are the dimensions of 60-630?
The SKF 60/630 measures 630 mm bore × 920 mm OD × 128 mm width (24.803 × 36.22 × 5.039 in), mass about 285000 g. It is open, with no shields or seals.
Why is there a slash in the designation 60/630?
The slash writes a bore that falls outside the two-digit code table: 60/630 means 630 mm bore. The site slug 60-630 replaces the slash with a hyphen.
How heavy is 60-630?
Catalogue mass is 285000 g for 60/630; seal and cage executions of the same envelope differ by a few grams.
What load can 60-630 take?
Catalogue values for 60/630: dynamic C 819 kN, static C0 1760 kN, fatigue limit Pu 27 kN. Use C in life calculation and C0 for static checks at 630 mm bore.
