SKF cam rollers are supplied greased. They are filled with the appropriate amount of a high-quality grease under clean conditions. The technical specifications of the grease are listed in table 1.
Single row cam rollers are greased for the life of the bearing and cannot be relubricated.
Double row cam rollers are also greased for the life of the bearing under normal operating conditions. If subjected to moisture or solid contaminants, or if they run for long periods at temperatures above 70 °C (160 °F) they should be relubricated. When relubricating double row cam rollers, the grease should be applied slowly to avoid damaging the shields or seals.
SKF supplies all inner rings for double row cam rollers with one lubrication hole. If suitable ducts are provided in the pin, the bearings are easy to relubricate.
