What are you configuring?

Precision-machined from high-alloy fine-grain steel billets. Select the product type to begin.

Application & Drive Type

How will this wheel be used and driven? Application context is optional; drive type recommends the bore configuration on the next step.

Application (optional)

Drives copy, soft-warning thresholds, and standards-compliance derivation. Does not constrain validation — any dimension within UTEC's envelope is valid regardless of application label.

Drive Type

Drives the recommended mounting type on the next step. Drive wheels need a keyway bore or a smooth bore with a heat-shrunk axle; idler wheels run on a smooth bore, slip-fit/press-fit bearing, or bronze bushing.

On a tapered profile, the corner-to-corner extent is wider than the flat surface by 2 × (overall_width / 2 × slope). On straight profiles the two are equal.
ℹ Wheels under 6″ aren't part of our standard catalog. For replacement wheels or short runs in this size, our team can quote on inquiry — sub-6″ orders work best at quantity.
UTEC's published flange-design rule sets minimum flange height by tread diameter: 1″ for 6–18″, 1¼″ for 19–30″, 1½″ above 30″. See Crane Wheel Flange Height & Angle Standards for the full rule. Values below the published minimum may require engineering review — call (509) 922-1832.
Heads up: flange height is below UTEC's published minimum of for a wheel. UTEC can machine to your specification — call (509) 922-1832 to confirm engineering review.

Axial dimension of the hub region. AIST TR-6 also calls this "hub thickness" — same dimension, different naming convention. UTEC normalizes to "Hub Length" across wheels and sheaves.

Overridden — ↻ Match rim width
Currently:
¹ How hub length defines the hub profile. Hub length is the axial dimension of the hub boss around the bore — measured in the same direction as rim width. AIST TR-6 also uses "hub thickness" for this dimension; same axial dimension, different naming convention.
  • Flat hub: hub length equals rim width — the hub face sits flush with the rim faces.
  • Positive boss: hub length greater than rim width — the hub protrudes past the rim.
  • Recessed hub: hub length less than rim width — the hub sits inset inside the rim envelope.
UTEC selects the profile automatically from these two dimensions; you'll see the derived choice on the Hub Profile step.
² How tread diameter is measured. Tread diameter is measured at the center of the tread (mid-width), regardless of tread profile (straight, tapered, crowned, or convex). Tapered and crowned profiles have a non-constant tread radius across the width; UTEC's convention is the mid-width radius — the radius at the axial midpoint of the running surface. Caliper or tape across the wheel through the center of the running surface is the right pickup.
Sheave Dimensions
Sheaves are drawing-driven. Most UTEC sheaves are machined to a customer-supplied drawing. Enter your dimensions below to get an estimate, then upload your drawing on Step 7 so our team can confirm the spec before production. For non-standard configurations, we may follow up with questions about flange or frame geometry.
Nominal wire rope diameter. Sheave groove geometry is derived from this dimension per ASME B30.2 and the Wire Rope Users Manual.
ASME B30.2 recommends a sheave-diameter-to-rope-diameter ratio of at least 18:1 for standard-service 6-strand rope (26:1 for rotation-resistant, 13:1 for utility applications).
Axial width of the sheave's rim region (containing the groove). UTEC follows your drawing — no published formula. The groove and rope-wall regions take at minimum (C + 2E); smaller values will surface a geometric warning. Enter rope diameter and outside diameter above to see the geometric minimum.
Outside diameter of the hub boss. Typically corresponds to a wear shim riding between the sheave and the surrounding frame. UTEC follows your drawing — no published formula.
Through-bore. UTEC produces bores down to 0.75″ standard; smaller bores available via drill-and-ream on request.
Axial length of the hub boss. Default is rim width + 0.5″ — a 1/4″ positive projection per side, UTEC's standard for sheaves. Override to flatten (= rim width), recess (< rim width), or set a different projection. (default applied: )
Hub profile (derived): Positive boss — hub face protrudes past the rim face on each side. Flat — hub face flush with the rim face on both sides. Recessed — hub face sits inside the rim face on each side. (Derived from L = ″ and P = ″.)

UTEC produces U-grooves only — the profile matched to wire rope per ASME B30.2 and the Wire Rope Users Manual. Other profile types (V, flat) are not offered.

Derived groove geometry:
  • Groove radius (C):
  • Groove depth (G): (1.5 × rope diameter)
  • Pitch diameter (A):
  • Root diameter (B):
  • Rope wall (min) (E):
  • Clearance offset (F): — rope rides on the groove sides, not the floor
  • Throat angle:
  • Shoulder fillets: 1/8″ inner / 1/4″ outer
Sheave groove — advanced override
Groove radius as a fraction of wire rope diameter. Industry-standard range per ASME B30.2 and the Wire Rope Users Manual: 0.53 to 0.55. UTEC's working defaults within that range are rope-size dependent — 0.535 for rope diameter 3/4″ or smaller, 0.55 for larger ropes — supporting the rope across ~120° of contact arc (one-third of its circumference).
Angle between the two groove walls flaring outward from the rounded bottom. 35° is the standard catalog value; 45° is the upper bound for normal applications and is rarely needed.

Carve an annular recess into each wheel face — independent of hub geometry. Removes material in the web region between the tread and the hub. Distinct from a recessed hub (UTE-164), which describes how the hub thickness compares to the overall wheel width.

Depth per side — customer override
Inset from tread — customer override

Defaults derived from overall width — depth = min(0.175 × OW, 2″); inset = 1.5″. See footnote ³ for how the pocket's hub-side and tread-side edges are computed.

³ How the face-recess pocket is positioned. The pocket is an annular slot carved into each rim face. UTEC sets its boundaries automatically from the wheel's dimensions:
  • Tread-side edge (closest to the tread): sits inset from tread radially below the running surface. Default 1.5″, customer-overridable above.
  • Hub-side edge (closest to the hub): extends to the hub-boss diameter exactly — the recess butts into the hub. This matches shop-floor machining: any thin annular shelf between recess and hub-boss is not producible, so UTEC machines the pocket down to the hub-boss diameter regardless of hub profile (flat, positive boss, or recessed hub).
  • Depth per side (axial): default min(0.175 × overall width, 2″); customer-overridable up to 2″ per side and ≤ 35% of overall width total. The depth is honored as-specified — UTEC does not silently adjust it for hub geometry. On a recessed hub configured deeper than the recess, the hub face sits axially inside the pocket; if the recess is deeper than the hub step, the hub appears as a short cylindrical pedestal inside the pocket.
The pocket is mirror-symmetric across the wheel's axial midplane and renders identically in the 2D and 3D previews.

Key Dimensions

Hardness & Treatment

UTEC supplies high-alloy fine-grain steel matching or exceeding the requirements of your hardness target and application. Specify your minimum alloy grade only if your engineering documentation requires one — UTEC will manufacture to your callout or supply an upward substitution.

In-house induction hardening with controlled case depth and pre-shipment hardness verification. Full raw material chemistry documentation on every order.

Hardness target
ℹ Sheaves are machined as thin-section components and are not suitable for UTEC's heavy-duty heat-treatment process. Standard heat-treatment is appropriate for typical sheave service; severe wire-rope wear applications require engineering review — call (509) 922-1832, email sales@utec.co, or upload your drawing for alloy and treatment options.

For customers whose engineering documentation requires a specific minimum grade. UTEC will manufacture to your callout or supply an upward substitution. Leave blank for UTEC default.

Mounting Type & Keyway

Mounting type follows from your drive-type choice; override here if your application differs. Keyway dimensions appear inline when a keyway bore is selected. Heat-shrink (thermal) installation is an option on Step 7 — independent of the mounting feature itself.

Default for drive wheels: smooth bore + thermally installed axle heat-shrink interference fit transmits torque without a key (override to keyway below)
ℹ Pick a drive type on to see the recommended mounting — or override below.

ℹ Smooth-bore drive wheels transmit torque through a heat-shrunk axle. Step 7 will auto-select Pre-assemble with a matching axle and Thermally install (locked) — these are required for the configuration to work mechanically.
Keyway

UTEC machines standard ANSI/ASME B17.1 keyways auto-sized to your bore diameter. Custom keyway dimensions are also available.
