NMFC 126880: Pulleys, Sheaves & Couplings | Cl 65-77.5

Note 126882: NOTE-Grooves of loose V-belt sheaves must be protected by lagging other than corrugated fiberboard.

To find the correct freight class for your shipment:

1. Confirm the part type fits this item: shaft pulleys or sheaves (see Note 126882), wooden pulley laggings, or shaft collars/couplings—excluding clutch couplings.
2. Select packaging by condition and size: palletize as packages or ship unitized loose with blocks. Wrap machined bores, cap keyways, and use VCI to prevent rust.
3. Record actual weight per unit for the weight-based class. If your shipment meets the heavier break, you may qualify for the lower class within 65–77.5.
4. Stabilize odd shapes: cradle heavy sheaves with timber wedges and through-bolts; bundle wooden laggings square with edge protectors; band collars in layers to avoid rolling.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Leverage weight breaks to reach Class 65 when possible, cutting LTL spend versus the higher class 77.5.
• Unified code for multiple motion components simplifies quoting and reduces reclass exposure on mixed-part pallets.
• Damage prevention on faces and bores lowers claim risk and avoids costly reshipments and linehaul delays.
• Non-hazmat status broadens carrier options and speeds tendering for machinery supply chains.
