Wacker Neuson 5000033692 Shaft Seal 25 X 35 X 6, 4B

The Wacker Neuson Shaft Seal 25 X 35 X 6, 4B is a genuine OEM component designed for the BTS 13 and BTS 11 gasoline cut-off saws. Sourced directly from Wacker Neuson, this seal carries the exact material grade, dimensional tolerancing, and compression rating specified for the original application. It is confirmed compatible with the BTS 13 cut-off saw with 1in arbor and the BTS 11 cut-off saw with 7/8in arbor, covering both common arbor configurations in the BTS saw family.

Key Features

• OEM Material and Dimensional Spec — Manufactured to the exact 25 x 35 x 6mm profile and seal-lip compound specified by Wacker Neuson, ensuring correct compression and sealing performance at the shaft interface.
• Drop-In Shaft Replacement — Seats directly into the original bore without modification, maintaining correct shaft alignment and bearing-cavity protection from the moment of installation.
• Confirmed BTS Saw Fitment — Verified for the BTS 13 (1in arbor) and BTS 11 (7/8in arbor) cut-off saws, covering both arbor variants within the BTS gasoline saw lineup.
• Protects Bearings and Internal Components — A healthy shaft seal keeps lubricant in and contaminants out; a worn or leaking seal allows dust, water, and debris to reach internal bearings, accelerating premature wear and failure.
• Genuine OEM Confidence — As an authentic Wacker Neuson part, 5000033692 meets the same production standards as the seal installed at the factory, with no guesswork on fit or material compatibility.

A shaft seal creates a dynamic barrier between a rotating shaft and its surrounding housing, retaining lubricant within the bearing cavity while blocking external contaminants such as dust, water, and cutting debris from entering the machine's internal components. In a gasoline cut-off saw like the BTS 13 or BTS 11, this seal is exposed to heavy vibration, heat, and abrasive debris generated during cutting operations, making its integrity critical to long-term bearing health. When the seal hardens, cracks, or loses its lip contact, lubricant migrates out and contaminants migrate in, leading to accelerated bearing wear, increased heat buildup, and eventual mechanical failure if left unaddressed.
