How the 22316 model number is decoded
Ordering number 22316 E in SKF catalogue PUB BU/P1 17000 denotes a double-row spherical roller bearing for a 80 mm shaft, dimension series 23 (heavy OD, wide), with open execution and a stamped window-type steel cage. Reading the designation: the leading 2 marks a spherical roller bearing, the 23 is the ISO 15 dimension series (dimension series 23 (heavy OD, wide)), and the last two digits encode the 80 mm bore; the 170 mm OD and 58 mm width follow the ISO 15 general plan. The trailing E is the SKF optimized internal design: larger rollers and a stamped window-type steel cage give higher load ratings than the older CC geometry; EK is the same bearing with a 1:12 tapered bore for adapter sleeves. At 3,000 r/min reference speed the 45.0 mm-section 22316 is governed thermally by lubricant flow through the W33 groove and the two-row roller complement; grease or oil selection should be made against that value, with 4,000 r/min as the mechanical ceiling. Mount with the spherical bearing's self-alignment in mind: it compensates ≈ 0.5–2.5° of misalignment depending on series, but the shaft and housing seats still set the datum — a rotating inner ring on a 80 mm shaft typically takes a k5 seat with an H7 housing bore.
Typical equipment & failure modes
Common applications
- heavy conveyor head shafts in mining
- jaw and cone crusher main shafts
- paper-machine press and dryer rolls
- rolling-mill pinion and back-up shafts
Known failure patterns
- raceway fatigue spalling of the sphered outer raceway after extended service above the catalogue L10 rating
- inner-ring raceway spalling from edge loading when misalignment exceeds the self-aligning recovery range
- cage pocket wear or fracture from roller skew at insufficient minimum load or rapid acceleration
- surface distress and smearing when the relubrication interval is exceeded — the W33 groove is only effective if grease actually reaches the roller rows
- fretting corrosion on a loose rotating shaft seat or in vibratory stand-still
Selection pitfalls — read before you substitute
- Mount the 80 mm bore 22316 by induction heating (max 120 °C) or oil injection — driving a bearing of this section home through the rollers brinells both raceways, and the damage only speaks up as vibration hours later.
- The 22300-series series at 80 mm bore (170×58 mm) is the heavy wide-section choice — highest capacity, lowest speed limit; do not substitute a 222 or 230 series in the same bore without re-checking both life and the 4,000 r/min ceiling.
- The self-aligning feature is not a license to ignore alignment: beyond ≈ 0.5–2.5° (series-dependent) the edge loading eats the fatigue margin, and seal drag grows as the rings tilt.
- Never use the tapered-bore EK/K variant's drive-up figures on this cylindrical-bore 22316; clearance reduction targets differ, and over-driving a cylindrical bore onto an oversized journal cracks the inner ring.
- The 516/530 kN ratings are SKF catalogue values for this exact execution (22316 E); SKF can revise internal geometry without changing the order number, so keep the catalogue version (SKF catalogue PUB BU/P1 17000) with the specification and re-verify for critical drives.
- SKF lists several executions of 22316 (cylindrical bore as listed, tapered-bore 22316 EK variant, plus sealed and vibrating-screen options in the same envelope); they are not interchangeable order numbers — quote the full 22316 E designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 22316?
The 22316 E is a double-row spherical roller bearing with 80 mm bore, 170 mm outer diameter and 58 mm width (3.15 × 6.693 × 2.283 in) per ISO 15. From SKF catalogue PUB BU/P1 17000: basic dynamic load rating C 516 kN, C0 530 kN, fatigue load limit Pu 54 kN, reference speed 3,000 r/min, limiting speed 4,000 r/min, mass about 6600 g. It is an open, self-aligning bearing with a stamped window-type steel cage.
How does the 22316 bore code work?
The last two digits of 22316 are bore code 16, so 16 × 5 = 80 mm bore. The 170 mm OD and 58 mm width come from the ISO 15 dimension-series plan (dimension series 23 (heavy OD, wide)), shared with other spherical roller bearings of the same code.
What does the E suffix mean on 22316?
E is the SKF optimized internal design with larger rollers and a stamped window-type steel cage for higher load ratings. The EK variant is the same bearing with a 1:12 tapered bore for adapter sleeves.
Can 22316 accommodate misalignment and axial load?
Yes on both counts. The sphered outer raceway lets the bearing self-align ≈ 0.5–2.5° depending on series, absorbing shaft deflection and housing-seat errors. The two barrel-roller rows also carry bidirectional axial load in addition to heavy radial load — this is the key difference from cylindrical roller bearings, which take no axial load.
When should the tapered-bore 22316K variant be used instead?
Choose the K (1:12 tapered bore) variant when the bearing must seat on an adapter or withdrawal sleeve — typical for long shafts, frequent dismounting, or stepped shafts where machining a precision journal is impractical. Sleeve mounting requires measuring clearance reduction or axial drive-up, not nut torque. The cylindrical-bore 22316 listed here seats directly on a machined journal.
