Klüber Lubrication, a worldwide manufacturer of specialty lubricants, has introduced Isoflex Topas NB 52 and Isoflex Topas NB 152, two rolling and plain bearing greases based on a synthetic hydrocarbon oil and a barium complex soap. The products are suited for amusement industry applications, such as roller coaster wheel bearings, in order to optimize operational reliability, cut servicing costs, conserve energy and extend maintenance intervals. The special barium-soap thickener used in the Isoflex Topas NB 52 and 152 greases offers good load-carrying capacity, as well as resistance to water and ambient media. Both products protect against corrosion, as well as oxidation and ageing.

Isoflex Topas NB 52 is suitable for temperatures ranging from -60°F to 250°F and short peak temperatures up to 300°F depending on the application. Isoflex Topas NB 152 can be used in a wide service temperature range of -40°F to 300°F. Isoflex Topas NB 52 is versatile for many applications, including:
•rolling and plain bearings subject to high speeds and loads, as well as low temperatures – ideal for road, side-guide, and up-stop wheels
•tooth flanks in precision gears, such as bevel gears in milling machines and electromechanical actuators for valves
•electric contacts and components to reduce insertion forces

Isoflex Topas NB 152 is compatible with many plastics and is used primarily for medium speed rolling and plain bearings, such as coaster wheels, wheel bearings in racing cars, fan bearings and pump bearings. The grease is also suitable for plastic/plastic or steel/plastic friction points.

“Using Isoflex Topas NB 52 and Isoflex Topas NB 152 greases leads to more consistent torque over a wide temperature range as well as longer component life when exposed to water or aqueous media,” said Stephen Mazzola, director of engineering and technical services for Klüber Lubrication North America L.P.

Mazzola recently conducted two training seminars on lubrication fundamentals and advanced lubrication of gears, bearings, chains at the Amusement Industry Manufacturers and Suppliers (AIMS) International Safety Seminar, Jan. 12-17 in Orlando. The AIMS International Safety Seminar is a comprehensive safety-training experience for individuals responsible for the care and safety of the amusement industry's guests.
