Taper Lock vs QD vs Split Taper Bushings
Taper lock, QD and split taper bushings solve a similar connection problem with different interface geometry. They should not be substituted by appearance alone.
| Family | Interface characteristic | Selection rule |
|---|---|---|
| Taper Lock | Compact flangeless-style family with an 8° included taper shown for the supplied taper-bushing series; tightening/removal-hole layout varies by size. | Use when the mating component is made for the matching taper-lock bushing size. |
| QD | Split quick-detachable bushing family with flange/barrel geometry and a dedicated mating hub/sheave/sprocket interface. | Use when the mating component is designed for the corresponding QD family. |
| Split Taper | Split bushing family offered in Type 1 and Type 2 configurations with multiple flange arrangements. | Use when the existing hub and split-taper interface match the selected type. |
