High strength stainless steel made ABBA Bearings are used for improving automation of different machines. These low noise and Eco friendly bearings can endure heavy load and these have excellent rigidity level. Utilization of these bearings can be noticed in semiconductor, solar equipment production and in medical equipment production industries. Offered low maintenance bearings have unique retainer design that prevents sudden displacement of its ball in case position of their slide block changes. Superior grade wool felt has been used in the plastic cover of the automatically lubricated block of these ABBA Bearings to prolong their working life.
