Rodriguez is offering a broad range of Kaydon bearing types from 100 to 6000mm diameter - with or without gears - for offshore use.
This bearing range is suitable for oil-platform cranes, davit maintenance cranes, drilling rigs, drives, offshore wind turbines and moorings buoys.
For the extreme conditions of such places as the North Sea, bearings are typically supplied with environmental protection of a zinc-phosphate coating and two-part paint finish, special grease and integral seals.
Kaydon bearings also meet the criteria for offshore crane bearings.
In accordance with the Lloyd's Register, Kaydon offers bearings that conform to the required material specifications and load safety ratings, including the Charpy V-notch compliance test where applicable.
The Kaydon four-point contact ball bearing is a popular choice.
It accepts combinations of radial, thrust and moment loads and uses races shaped like gothic arches on both the inner and outer race ball paths.
These generate four points of contact on each ball.
To satisfy requirements for high load capacity within a given envelope, especially in large-sized bearings, Rodriguez also offers a Kaydon eight-point contact design.
This is a bearing with two rows of balls, the unique feature of which is its use of gothic-arch internal geometry in both rows.
Tests have confirmed that this additional row increases load capacity by 80 per cent.
For the highest capacity, the choice includes three-roller bearings.
The top and bottom rows absorb thrust loading and in combination they also handle moment loading.
The intermediate row addresses radial loading and because each row operates independently, frictional torque is low.
