The DEFENDER Linear Rail linear bearing system is designed to be washed down with disinfectants or high strength industrial cleaners and is ideal for use with draw and rack glides, and sliding doors. The bearing rails are rolled 304 stainless with an internal bearing race. Each bearing slider unit is 80 mm (3.15 inches) long. Each 440C stainless steel ball bearing roller is lubricated for life, features 2RS seals, and can be washed down. The slider’s center bearing is mounted on an eccentric shaft for adjusting the preload. The cross section of the compact bearing and slider is 26 mm x .22 mm (1.02 in. x .866 in.). The rails are available in lengths of 1040 mm (40.94 in.), 1520 mm (59.84 in.), 2080 mm (81.89 in.), and 3120 mm (122.83 in.) or in cut to order sizes.
