ROCKWELL AUTOMOTIVE UNVEILS NEW PERMALUBE U-JOINTS

 LAS VEGAS, March 22 /PRNewswire/ -- Rockwell International Corporation's Off-Highway Products business has announced the introduction and immediate availability of a family of permanently lubricated universal joints that will reduce maintenance costs and vehicle downtime.
 Called Permalube, the new family of medium- and heavy-duty u-joints are lubricated and sealed during assembly, thereby requiring virtually no maintenance.
 Rockwell's driveline development was announced here at CONEXPO '93.
 Tom Sanko, product manager of Drivelines, said that with specific applications for the off-highway construction market, the company's new line of Permalube u-joints will virtually eliminate time-consuming preventive maintenance on hard-to-reach drivelines.
 "Given the construction of most off-highway vehicles, lubricating u-joints can be extremely difficult," Sanko said. "Rockwell's Permalube product line will eliminate this need and keep vehicles in the field where they belong."
 A new concept incorporated in Permalube u-joints is the introduction of a two-piece thrust washer. The independent thrust washers allow relative motion between the needle bearings and trunnion to minimize wear and help extend life.
 Sanko said a large outer thrust washer absorbs loads from the needle bearings, protecting them from damage while aligning the needles with the trunnion for maximum surface contact. Additionally, a smaller inner thrust washer, grooved to provide a grease passage, protects the end of the trunnion against end galling.
 According to the company, the Permalube u-joint's superior bearing package is protected by triple-lip seals and rugged metal deflectors that work together to provide an effective barrier to contaminants. The new u-joint also features a high-performance grease packed during assembly. Developed for its outstanding wear and temperature properties, this specially formulated grease is designed to keep the bearings thoroughly lubricated for life.
 Covering the complete line of medium- and heavy-duty applications, Permalube u-joints are available in the following series: 62N, 58WB, 72N, 82N, 85WB and 92N.
 Rockwell's Off-Highway Products supplies vehicle manufacturers around the world with high-quality, cost-effective drivetrain component systems including a variety of planetary drive axles; transfer cases; wet and dry disc, wedge, cam, hydraulic and mechanical drum brakes; friction materials and supporting aftermarket parts.
