The Multiquip 582020 Taper-Lock Bushing 1615 x 1-1/5 is a genuine OEM component designed for SP, PS, and CS series pavement saws, including models SP303520, SP303526, SP303530, PS403016, PS403020, PS403026. As a direct OEM replacement, part 582020 is manufactured to the same specifications as the original, ensuring an accurate fit with no guesswork on installation. This bushing is a critical drivetrain component that keeps your blade hub and shaft assembly properly coupled during saw operation. Sourced directly through Multiquip's authorized parts network, this is the correct part for maintaining the integrity of your pavement saw's drive system.
Key Features
- Genuine OEM Taper-Lock Tolerancing — Machined to the exact 1615 bore profile for secure, concentric hub engagement with no slippage under load.
- Drop-In Hub Replacement — Matches the original taper angle and keyway dimensions for straightforward installation into compatible hub assemblies.
- Broad Pavement Saw Compatibility — Fits SP, PS, and CS series models across multiple blade diameter configurations, including 303516 through 403030 variants.
- Drivetrain Integrity Under Cutting Load — A correctly seated taper-lock bushing transmits torque evenly to the blade arbor, preventing vibration, hub wobble, and premature bearing wear.
- Blade Safety Assurance — A worn or improperly fitted bushing can allow blade hub movement during cutting, posing a serious operational hazard; replacing with the correct OEM part restores secure blade retention.
A taper-lock bushing is a precision-machined hub insert that locks a pulley, sprocket, or blade hub firmly onto a shaft using a self-tightening taper fit secured by clamping screws. In a pavement saw, it connects the drive hub to the blade arbor shaft, transferring engine torque directly to the cutting blade. When this bushing becomes worn, cracked, or loose, it can cause blade wobble, uneven cuts, accelerated bearing damage, and unsafe blade retention — making timely replacement essential to both cut quality and operator safety.
