How the 32014-SKF model number is decoded

Ordering number SKF 32014 X in SKF catalogue PUB BU/P1 17000 denotes a single-row tapered roller bearing for a 70 mm shaft, low-friction section, with an open pressed-steel-cage execution and one-direction axial capacity.Reading the designation: the leading 3 marks a single-row tapered roller bearing, the 20 is the ISO 355 diameter/width series (low-friction section), and the last two digits encode the 70 mm bore; the 110 mm OD and 25 mm width follow the ISO 355 general plan. In SKF suffix language a bare 32014 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. The 20.0 mm radial section height ((110−70)/2) and 850 g catalogue mass frame a 70 mm bore bearing rated at 125 kN C — roughly 1.79 kN of dynamic capacity per millimetre of bore before application factors. Note the minimum-axial-load requirement: at light radial load and high speed the rollers of 32014 must still be held into the rib contact, which is another reason the catalogue recommends paired mounting with controlled setting. Journal and housing interface: the 70 mm bore takes a k5 shaft seat (upper deviation ~0.140 mm for this diameter range) and the 110 mm outside diameter pairs with an H7 housing bore tolerance band of 110.000/110.020 mm; the 25 mm width defines the shoulder depth, and the 850 g cone-plus-cup assembly is the dead load on the shaft during thermal expansion calculations.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount the 70 mm bore 32014 by induction heating of the cone (max 120 °C — the pressed-steel cage sets the ceiling, not the steel); driving it home through the cup or rollers brinells the tapered raceway.
• The 320 series at 70 mm bore (110×25 mm) is the low-friction, higher-speed section; it carries less thrust than a 30214 of the same bore, so verify the axial load share before swapping.
• The tapered contact angle creates an induced axial load under pure radial force; include it in the 32014 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
• Setting is a design value, not an assembly feel: excessive preload in the 32014 pair raises operating temperature and can trigger thermal runaway, while too little lets the rollers skid and smear the raceway under light load.
• The 850 g mass and 25 mm width mean spacer and abutment faces must be square to the axis within the bearing's own P0 tolerance; a tilted spacer tilts the contact angle and concentrates load on one rib of 32014.
• The 125/153 kN ratings are SKF catalogue 17000 values for the basic execution; SKF can revise internal geometry without changing the order number, so keep the catalogue version (PUB BU/P1 17000/1 EN, 2018) with the specification and re-verify for critical drives.
• SKF lists several executions of 32014 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 32014 X designation when purchasing and match the execution to the mounting arrangement.
