Shell Stamina Grease RL 1 High-Temperature Urea Grease for Centralized Lubrication
Shell Stamina Grease RL 1 is a high-temperature urea-thickened grease from Shell. Shell Lubricants Japan describes the Stamina Grease RL family as heat-resistant greases using a special urea thickener, with RL0 and RL1 specifically recommended for centralized lubrication of bearings operating at high temperatures. The current Japanese SDS identifies Stamina Grease RL 1 as a lubricating grease containing highly refined mineral oils and additives. It is a light-brown semi-solid at ambient temperature and has a dropping point of at least 234°C.
