Bushing Systems Explained
Unlike bearings and V-belts, sheaves carry a bushing system attribute that determines how the sheave mounts to the shaft. Different bushing systems aren't interchangeable between brands without re-keying the drive.
- Fixed-bore (H suffix): Cast-iron sheave with a finished bore — no bushing, no setscrew. Browning's AKxxH / BKxxH lines are the common reference.
- Split-taper (Browning B): Two-piece taper bushing seated in a matching split-taper hub. Browning's patented split-taper system is the industry baseline; PowerDrive and MasterDrive match it directly.
- Q-D (Quick-Disconnect): Single-piece tapered bushing with bolted flange. Sizes SD / SH / SF / SK / E / F / J / M / N / P / W. Browning's TC/TA prefixes use Q-D bushings.
- Taper-Lock: Single-piece tapered bushing in standardized international sizes (1008, 1108, 1210, 1610, 2517, 3020, …). Used by metric drives and TB Wood's.
Why Sheave Part Numbers Match (Or Don't)
The Browning naming convention is the de-facto industry standard for industrial sheaves. PowerDrive, MasterDrive, and Martin all list the same canonical PNs as Browning for direct-equivalent products. Maska is the consistent name-divergence brand: where Browning calls a sheave 68V1600S1, Maska typically calls it MA-series using the legacy Maska naming convention.
TB Wood's historically used its own PN system as well, though it has aligned with Browning conventions for newer product lines.
For sourcing purposes, all five brands listed in the table above produce the same physical sheave to the same RMA/MPTA dimensional standards. Brand choice comes down to availability, price, and warranty preference rather than fit.
Frequently Asked Questions
Can I replace a Browning 68V1600S1 with Maska ?
Yes. Both refer to the same physical sheave — same groove profile, same diameter, same bushing system. Direct drop-in replacement. The brand differences (casting grade, balance class) affect service life under extreme conditions but not fit.
Which brand of 68V1600S1 sheave is best?
Browning is the canonical brand and is widely considered the premium industrial sheave. PowerDrive and MasterDrive are direct OEM-equivalent quality. Maska is a long-standing North-American manufacturer with strong distributor coverage. TB Wood's positions on value pricing. For standard drive applications all five produce dimensionally identical sheaves.
What's the difference between 68V1600S1 and the same sheave with a different bushing?
The bushing system determines the shaft mount and bore range. A 8V-profile sheave at the same diameter is available in fixed-bore (H suffix), split-taper, Q-D, or Taper-Lock variants — each is a separate canonical PN. The bushing system isn't interchangeable mid-drive without re-keying the shaft.
