The balls of some bearings in the 12 and 13 series protrude from the side faces of the bearing (fig. 1). The values of the protrusion are listed in the product table and should be considered when designing components in close proximity to the bearing.
- adapter sleeve on plain (a) or stepped shafts (b) (fig. 2)
- withdrawal sleeve on stepped shafts (fig. 3)
Adapter sleeves are supplied complete with a locking device.
Appropriate SKF adapter sleeve (→ product table).
When using sealed bearings, make sure appropriate SKF adapter sleeve assemblies (e.g. E design sleeve, → product table) are used to prevent the locking device from interfering with the seal (fig. 4). Alternatively, use a spacer ring between the bearing and the lock washer.
When two of these bearings are used to support a shaft, to locate the shaft axially the inner ring slots must be arranged facing towards or away from each other (fig. 5).
Appropriate SKF housings are available in a variety of designs and sizes for a wide range of applications. The designs include:
- SNL, SE plummer (pillow) block housings in the 2, 3, 5 and 6 series
- FNL flanged housings
- SAF plummer (pillow) block housings for inch shafts
