How the 61919 model number is decoded
61919 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the thin 619xx section (diameter series 9 of ISO 15), multiplying bore code 19 by five gives the 95 mm bore; the 130 mm outside diameter and 18 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 95 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
Typical equipment & failure modes
Common applications
- space-constrained gearboxes
- clutch and transmission assemblies
- robotics and automation joints
- lay shafts and idler shafts
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
Selection pitfalls — read before you substitute
- At 95 mm bore the ring mass is significant: heat 61919 on an induction heater (max 120 °C), never over an open flame, and plan puller access or a withdrawal sleeve now for the day it has to come off again.
- The 619xx thin section (17.5 mm section height at 95 mm bore) trades load capacity for compactness; stiff, accurately aligned seats are essential or edge loading will spall the raceway early.
- The open 61919 has no lubricant retention: grease escapes and contaminants migrate straight into the 95×130×18 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 61919 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
- Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 18 mm-wide ring of 61919 drags the lip and overheats it.
- Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
- The open 61919 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 61919-2Z (shields) and 61919-2RSH (contact seals), not suffix-free 61919.
- The 33.8/33.5 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 61919 bearing?
A 61919 deep-groove ball bearing has a 95 mm bore, 130 mm outer diameter and 18 mm width (3.74 × 5.118 × 0.709 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
How should 61919 be mounted?
Apply the mounting force to the ring being fitted: on a 95 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 61919 need?
The open 61919 is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.
How does the 61919 bore code work?
The last two digits of 61919 are bore code 19, giving 19 × 5 = 95 mm bore. The 130 mm outside diameter and 18 mm width follow the ISO 15 diameter series, not the bore code alone.
What is the SKF designation and catalogue data for 61919?
In the SKF Rolling Bearings catalogue this size is listed as 61919 — the open (unsealed) execution, 95×130×18 mm per ISO 15. Quoted values: C 33.8 kN, C0 33.5 kN, Pu 1.34 kN, limiting speed 6300 r/min, mass 610 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 61919.
