How the 368A-362A model number is decoded

In SKF inch-series tables 368A sits at 50.8 mm bore (2 in) with a 88.9 mm cup OD and 20.638 mm total width — dimensions that trace back to the original Timken boundary plan for the 365-series family. SKF lists the plain number as the basic execution; letter suffixes such as B denote a steeper contact angle and are different order numbers. The 19.1 mm radial section height ((88.9−50.8)/2) and 500 g catalogue mass frame a 50.8 mm bore bearing rated at 94 kN C — roughly 1.85 kN of dynamic capacity per millimetre of bore before application factors. A single 368A locates the shaft in one axial direction only; mount it against a second bearing in O (back-to-back) or X (face-to-face) arrangement, and set the running clearance by the mounting procedure — not by feel. Journal and housing interface: the 50.8 mm bore takes a k5 shaft seat (upper deviation ~0.102 mm for this diameter range) and the 88.9 mm outside diameter pairs with an H7 housing bore tolerance band of 88.9.000/88.920 mm; the 20.638 mm width defines the shoulder depth, and the 500 g cone-plus-cup assembly is the dead load on the shaft during thermal expansion calculations. Housing and abutment design flows from the cup: in 368A the 362 A cup fixes the 88.9 mm OD, the outer-ring face position and the rib shoulder that the rollers contact under thrust, while the 368 A cone determines the 50.8 mm shaft interface; the 20.638 mm width is the assembled pair value.Ordering number SKF 368 A/362 A in SKF catalogue PUB BU/P1 17000 denotes a single-row tapered roller bearing for a 50.8 mm shaft, inch series, with an open pressed-steel-cage execution and one-direction axial capacity.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• On this 50.8 mm bore, interference and temperature rise consume clearance inside a preloaded pair; calculate the residual clearance after mounting and at operating temperature — an over-tight 368A pair heats, loses setting control and smears the roller-rib contact.
• The 320 series at 50.8 mm bore (88.9×20.638 mm) is the low-friction, higher-speed section; it carries less thrust than a 302 of the same bore, so verify the axial load share before swapping.
• A single 368A cannot locate the shaft axially in both directions; mounting it singly on a reversing-thrust shaft leaves one direction uncontrolled — always use an O or X matched pair for bidirectional location.
• When the outer ring rotates, reverse the fit logic and provide cup location; the tapered contact of 368A pushes the rings apart under load, so a non-located cup walks its seat even when the shaft is fixed.
• The pressed-steel cage is rated for standard industrial service; sustained running above the limiting speed or with degraded lubricant wears the cage pockets — inspect the cage at every relubrication interval.
• The 94/91.5 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 368A (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 368 A/362 A designation when purchasing and match the execution to the mounting arrangement.
