Type 5 self aligning rudder bearings

Designed specifically for MOTOR YACHTS with metallic rudderstock the Type 5 bearing is an all steel heavy-duty spherical roller bearing.

The spherical roller bearing is housed in an oil filled aluminum alloy housing and is protected a triple quad ring seals in which seal carrier allow up to 1.5 deg of stock deflection.

Type 5 bearings are able to withstand incredible radial loads. 

• Type 5 bearings can be used as both upper and lower bearings. 

• The barrel shaped rollers and spherical outer housing allows the bearing to self-align 1.5 deg while the rudderstock rotates within the bearing. 

• Outer housings are machined from solid marine grade aluminium and are anodised in our in-house anodisation plant to ensure quality and prevent corrosive action. 

• Bearing casing is oil filled to prevent condensation with in the bearing. 

• 3 quad ring seals located in a seal carrier seal to ensure the bearing is watertight and allow for stock deflection. 

• Bearings are available in any size from 70mm upwards. 

• Type 5 bearings have been classification society approved in the past and can be for your project on request.

Type 5 Bearing Designation

All JP3 bearings designations follow a common format:
The first 2 numbers refer to the bearing type and model,in this case Type 5.

The second numbers refer  to the number of rows of rollers and mounting style
The last 2 numbers designate the stock diameter in centimeters. i.e. 50.XX.09 will be a 90mm.

Housing Styles

Type 5 bearings can be installed into either composite or metal hulls and in one of 2 housing styles, JP3 furniture. 

We can also offer you to machine the cartridge, ensuring an easy installation

Bearing Sizes and Load Ratings

* The `XX” designation refers to the housing style. Each size is available in the 3 housing sizes.

** Bearing loads vary with stock size. The figures given are for minimum and maximum stock sizes.
