The Multiquip HS006000010 Upper Crankshaft Bearing is a genuine OEM component designed for HS81A, HS81, and SHS81A high speed cut-off saws. Sourced directly from Multiquip, this bearing meets the exact tolerancing and load ratings specified for the sidewinder-style cut-off saw platform. It is a direct-fit replacement for both Multiquip and STOW-branded models in this family, so you can install with confidence knowing the geometry and fit are correct. DHS Equipment stocks this part to keep your saws turning and your crew on schedule.
Key Features
- Precision OEM Tolerancing — Manufactured to Multiquip's exact radial load and dimensional specifications for the upper crankshaft position, ensuring smooth, consistent rotation under high-cycle cutting loads.
- Drop-In Installation — Engineered to seat directly into the upper crankshaft housing of compatible sidewinder cut-off saws with no rework or modification to the bearing bore.
- Broad Sidewinder Saw Compatibility — Fits HS81A, HS81, and SHS81A models, covering both Multiquip and STOW High Speed Cut-Off Saw variants in a single part number.
- Protects Crankshaft Integrity — A worn or seized upper crankshaft bearing places lateral stress on the crankshaft journal, accelerating wear across the entire bottom end. Replacing at the first sign of noise or play keeps the crankshaft running true.
- Genuine OEM Part — Supplied as an authentic Multiquip component under part number HS006000010, with no ambiguity about material grade or dimensional accuracy.
The upper crankshaft bearing supports the top end of the crankshaft, maintaining proper alignment between the crankshaft and the engine housing during operation. In a high-speed cut-off saw, this bearing absorbs the radial forces generated by rapid blade rotation and engine vibration, allowing the crankshaft to spin freely with minimal friction. When this bearing wears, develops play, or seizes, it can cause audible knocking, increased vibration, difficulty starting, and — if left unaddressed — crankshaft damage that requires a far more extensive repair.
