How the HM804846-810 model number is decoded

At 5,600 r/min reference speed the 24.6 mm-section HM804846 is governed thermally by preload and lubricant flow; grease or oil selection should be made against that value, with 7,000 r/min as the mechanical ceiling. Fit selection follows the rotating ring — interference on a rotating cone — and two HM804846 units are required to take reversing thrust; keep the induced axial load inside the rated capacity when calculating the pair. Load system: the 133 kN basic dynamic rating C and 146 kN static rating C0 give a C0/C balance of 1.10, and dividing C by the 46.038 mm bore yields 2.89 kN per millimetre of journal — a density metric that compares across families; the 17.3 kN fatigue limit Pu is the floor beneath which the adjusted-life calculation drops below acceptable L10 hours for a 46.038 mm shaft carrying variable duty. Cup-side note for 810: the outer ring's rib profile and the 95.25 mm outside diameter are cup-specific within the HM804800-series tables, so substituting a different cup against the same HM 804846 cone changes both the assembled 30.162 mm width and the axial free-play setting of the mounted pair.Ordering number SKF HM 804846/810 in SKF catalogue PUB BU/P1 17000 denotes a single-row tapered roller bearing for a 46.038 mm shaft, inch series, with an open pressed-steel-cage execution and one-direction axial capacity.The code breaks down as cone/cup: the numbers before and after the slash identify the inner and outer ring sets, and the series prefix (HM804800-series) ties the pair to a specific boundary plan. Dimensions 46.038×95.25×30.162 mm are the converted metric envelope. SKF lists the plain number as the basic execution; letter suffixes such as B denote a steeper contact angle and are different order numbers.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• On this 46.038 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 HM804846 pair heats, loses setting control and smears the roller-rib contact.
• The HM804800-series inch series at 46.038 mm bore (95.25×30.162 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.
• The tapered contact angle creates an induced axial load under pure radial force; include it in the HM804846 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
• The tapered contact angle creates an induced axial load under pure radial force; include it in the HM804846 rating calculation (and account for it in both bearings of a pair) or the unloaded bearing skids its rollers.
• The 990 g mass and 30.162 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 HM804846.
• The 133/146 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 HM804846 (basic, B steeper angle, Q/J2 clearance variants); they are not interchangeable order numbers — quote the full SKF HM 804846/810 designation when purchasing and match the execution to the mounting arrangement.
