How the 32014 model number is decoded

Ordering number 32014-X-XL in Schaeffler HR1 (2022 edition) 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 2 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 Schaeffler notation 32014-X-XL is the basic X-life execution; B-suffix variants have a steeper contact angle and are not interchangeable with the base bearing. The 20.0 mm radial section height ((110−70)/2) and 880 g catalogue mass frame a 70 mm bore bearing rated at 123 kN C — roughly 1.76 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.

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 880 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 123/159 kN ratings are Schaeffler HR1 values for the X-life execution; the -XL suffix denotes the premium grade and is part of the order designation, so quote it in full when purchasing.
• Schaeffler lists 32014 in the X-life basic execution; variant executions with -B or other suffixes are separate order numbers and are not interchangeable with the basic X-life bearing.
