How the 462-453X model number is decoded

Mounting practice for 462: the rotating cone takes the interference fit (k5 on a 53.975 mm shaft), the cup slides for axial location, and reversing-thrust duty demands a paired O/X set rather than one bearing. Journal and housing interface: the 53.975 mm bore takes a k5 shaft seat (upper deviation ~0.108 mm for this diameter range) and the 104.775 mm outside diameter pairs with an H7 housing bore tolerance band of 104.775.000/104.795 mm; the 30.162 mm width defines the shoulder depth, and the 1050 g cone-plus-cup assembly is the dead load on the shaft during thermal expansion calculations. Cone-and-cup identity in 462: the leading 462 reference identifies the inner ring, rollers and cage; the trailing 453 X reference identifies the outer ring. The 455-series series lists alternative cups for the same cone, each producing a different 104.775 mm OD or 30.162 mm width — hence a different SKU even though the bore stays at 53.975 mm.462 is a single-row tapered roller bearing in the 455-series inch series: a separable cone-and-cup design for combined radial and one-direction axial load, listed by SKF in SKF catalogue PUB BU/P1 17000.Reading the designation: 462 follows the Timken-style inch convention — the cone (inner ring with rollers) and cup (outer ring) are quoted as a pair separated by a slash, and the 455-series code identifies the dimensional series. The 53.975 mm bore, 104.775 mm OD and 30.162 mm width are the metric equivalents of the inch boundary dimensions. In SKF suffix language a bare 462 is the standard execution; B marks a larger contact angle and Q or J2 mark clearance/cage variants, all quoted separately. Catalogue mass 1050 g for the 53.975×104.775×30.162 mm open execution covers the pressed-steel cage and standard roller complement; sealed or special-clearance variants differ slightly in mass and carry their own order numbers.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• On this 53.975 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 462 pair heats, loses setting control and smears the roller-rib contact.
• The 455-series inch series at 53.975 mm bore (104.775×30.162 mm) follows the Timken cone/cup convention; substitutions must match both the cone and cup reference exactly — interchanging with another series or a metric 3xxxx bearing of the same bore changes OD, width and contact angle, so re-run the pair setting and shoulder-diameter checks before swapping.
• A single 462 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.
• The tapered contact angle creates an induced axial load under pure radial force; include it in the 462 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
• The 462 shares its ISO 355 envelope with other tapered bearings of the same code but is not a drop-in replacement for a ball bearing: it cannot run effectively under pure radial load without a minimum axial load, and a deep-groove bearing cannot replace its combined-load duty.
• The 150/160 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 462 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF 462/453 X designation when purchasing and match the execution to the mounting arrangement.
