The Multiquip 13277Y Boss Bearing is a genuine OEM Boss Bearing designed for the MS-40M masonry saw. Sourced directly from Multiquip, this part meets the exact specifications of the original component installed at the factory. It is a direct-fit replacement for MS-40M machines, slotting into position without the need for modification. Keeping the correct Boss Bearing in service ensures the blade hub assembly operates with the precision your masonry saw demands.
Key Features
- OEM-Grade Load Tolerance — Manufactured to the same dimensional and load-bearing specifications as the original, maintaining correct rotational alignment in the blade boss assembly.
- Direct Replacement for MS-40M — Engineered specifically for the Multiquip MS-40M masonry saw, this bearing seats into the boss housing exactly as the factory-installed component does.
- Smooth Blade Hub Rotation — A properly functioning Boss Bearing allows the blade hub to spin freely and true, supporting clean, consistent cuts through masonry and tile materials.
- Wear-Resistance Under Sustained Load — Masonry saw bearings endure continuous rotational stress and slurry exposure; this OEM part is rated for the operating conditions the MS-40M is built around.
- Blade Safety Alignment — A failed or worn boss bearing can cause blade wobble and loss of cutting control; using the correct OEM replacement maintains the blade's true running path and operator safety.
The Boss Bearing supports the blade hub — or boss — on the masonry saw's spindle, allowing the cutting blade to rotate smoothly and concentrically under load. It carries both the radial forces generated by blade contact with masonry materials and the axial loads from the blade clamping assembly. When this bearing wears or fails, the blade can develop runout, causing uneven cuts, increased vibration, accelerated blade wear, and potential loss of cutting control.
