How the 1319 model number is decoded
In the 1300-series (ISO 15 dimension series) the leading digits 13 mark a double-row self-aligning ball bearing and the last two digits encode the bore: 1319 carries bore code 19 = 95 mm. Outside diameter 200 mm and width 45 mm follow the ISO 15 general plan. The cylindrical bore fits directly on a machined shaft seat; a tapered-bore K variant is available for adapter-sleeve mounting. Two rows of balls run on a common sphered outer raceway, allowing the inner ring to pivot and compensate for shaft deflection or housing misalignment.
Typical equipment & failure modes
Common applications
- hoist, winch and crane drums
- heavy conveyor drive shafts
- pulp, paper and steel mill machinery
- heavy industrial drive shafts
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- false brinelling from vibration while the shaft is stationary
- edge loading and stress concentration from excessive misalignment beyond the allowable angle
Selection pitfalls — read before you substitute
- Mount this 95 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 13xx medium section at 95 mm bore gains rating through a larger 200 mm OD and 45 mm width; verify the housing accepts the larger envelope before substituting for a 1219.
- The open 1319 has no lubricant retention: grease escapes and contaminants migrate straight into the 95×200×45 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 1300-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 1319 units.
- Self-aligning ball bearings have lower axial load capacity than same-size angular-contact or tapered-roller bearings; verify the axial component is within the Y-factor limits for 1319.
Frequently asked questions
What are the dimensions of a 1319 self-aligning ball bearing?
A 1319 self-aligning ball bearing has a 95 mm bore, 200 mm outer diameter and 45 mm width, per ISO 15 boundary dimensions. This is the cylindrical-bore version; a tapered-bore K variant is available for adapter-sleeve mounting.
How does the 1319 bore code work?
The last two digits of 1319 are bore code 19, giving 19 × 5 = 95 mm bore. The 200 mm outside diameter and 45 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the open suffix mean on 1319?
A bare 1319 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
How does the 1300 compare with other self-aligning series at the same 95 mm bore?
The 13xx is the medium section: 200×45 mm, 52.5 mm radial section at 95 mm bore, carrying more load than a 1219 but needing a larger housing bore.
