Rubber bearing and rubber bushing for propeller shaft and maritime shaft line for inboard engines and the boat's shaft system. The metric variants are manufactured entirely from rubber and function as a bearing or bushing between the propeller shaft and the bearing housing, stern tube, or bearing seat.
The product family includes cylindrical designs with a profiled or hollow internal bore, as well as select variants with a flared or flanged end. No separate outer shell of metal or resin is documented. Dimensions are specified as internal diameter × external diameter × length:
Ø22 × Ø29 × 75 mm
Ø22 × Ø36 × 80 mm
Ø25 × Ø36 × 100 mm
Ø25 × Ø40 × 120 mm
Ø30 × Ø40 × 120 mm
Ø35 × Ø54 × 140 mm
Ø40 × Ø54 × 140 mm
When selecting the correct variant, the nominal diameter of the propeller shaft, the internal diameter of the bearing housing or stern tube, and the available mounting length must be checked. Dimensions are critical for compatibility, as no compatibility with specific boat brands, engine manufacturers, drives, or boat models is specified.
Mounting tolerances, bearing clearance, and separate dimensions for any flanges or flared ends are not specified and must therefore be verified against the specific shaft line. Always check the dimensions of the existing bearing, shaft, and bearing seat before ordering and installation.
