Bearing Radial Clearance Checking Machine

Bonetto of Italy specialise in the manufacture of automatic machines Model H-70 for the assembly and testing of ball bearings. Model H-70 is suitable for checking the radial clearance in deep-groove ball bearings of OD ranging between 55 mm and 110 rnm. The cycle operates by radially loading the bearing while in rotation, in opposite directions. Based on the values obtained, the radial clearance value is determined. The radial load on the bearings is adjustable. The checking method employed can also determine the ovality in the bearings, displaying it visually on a monitor. The machine operates with a PLC. The cycle-time is 5.5 secs, for an hourly output of approximately 650 bearings. Set-up time is 35 minutes. Other machines manufactured by Bonetto include automatic machines for ring selection and pairing; Ball filling; Cage insertion and riveting; Grease filling; Dust shield fitting; and Noise level checking. These machines are suitable for mass production of bearings of the first quality.
