Features
- Improved extrusion resistance compared to standard FKM or NBR backups
- Can be stretched over larger diameters and will return quickly to their original size
- High strength and abrasion resistance
- Wide temperature range
- Chemical resistance
- Low friction
- Easy installation
Kraken marine bearings are rubber-lined brass bearings that are compatible with various shaft sizes and suitable for a wide range of marine vessels, from pleasure boats to commercial ships. They are designed for use as stern tube bearings, strut bearings, and rudder or pintle bearings.
Constructed with durable rubber and corrosion-resistant brass, Kraken bearings offer exceptional wear resistance, even in harsh marine environments. Kraken bearings reduce friction and absorb forces generated by shaft rotation, ensuring smooth operation, and extending the lifespan of the propulsion system.
The precision-engineered design ensures proper alignment and reduces vibration, resulting in quieter operation and minimized stress on the shaft. The grinding method used in the manufacturing process ensures a concentric bearing that meets or exceeds clearance and tolerance as per U.S. Navy Standard, BuShips plan number 810-1385664.
A cutlass bearing, also known as a stern tube or strut bearing, is a crucial component in marine propulsion systems. It supports and aligns the propeller shaft within the boat’s strut or stern tube. Regular maintenance is necessary to detect wear or damage and maintain optimal performance.
Kraken bearings can also be used in industrial applications such as pump bearings for power plants or wastewater treatment plants.
- Reduced vibration
- Quiet operation
- Concentric design
- Long service life

SB22ES has a 0.875 in ID.
The bushing is Unsealed and made of forged steel. The ball will swivel like a fish eye with 3-5 degrees of movement.
Each Seal Guard Wiper consists of two flexible bronze rings which are held in place by a nitrile cushion ring. The cushion ring absorbs side loads and energizes the wiper to maintain close contact with the rod. Particularly suited for hostile environments, seal guard wipers shave off sand, grift, slag, flux, paint, moisture, chips and slivers. Seal Guard Wipers are long-lasting, self-adjusting, and offer low friction. Seal Guard Wipers can be installed in standard Hercules® Sealing Products “ST” or “D” Style grooves by increasing the “F” gland dimension to the “F” Throat Diameter shown.
