NACHI Super Precision Bearing 7216CYDUP4, Universal Ground, Duplex, 80MM Bore, 140MM OD

NACHI Features Small Ball Diameter & Optimum Internal Design generate higher speed and lower heat generation Interchangeable with 7000 series with identical boundary dimensions Two bearings are used in a duplex pair to provide a high degree of rigidity in both radial & axial directions Meets the needs of machine tool manufacturers for precision bearings (15° contact angle, P4) that can operate at lowest possible temperature for wide range of speeds & operating loads These Universal Flush Ground Bearings can be mounted in DB, DF or DT

NACHI Features Two single row angular contact ball bearings (15° contact angle P4) are assembled to provide a high degree of rigidity in both radial & axial directions These Universal Flush Ground bearings can be mounted in DB, DF or DT Meets the needs of machine tool manufacturers for precision These bearings function at lowest possible temperature for wide range of speeds & operating loads

Features NACHI Sheave Bearing is a Double Row Full Compliment Cylindrical Roller Bearing Since the bearing carries the highest Dynamic & Static Load Ratings, it is highly recommended for Rope Sheave applications If snap rings are used on both sides of outer ring, it is easy to set the axial location of the bearing Re-lubrication can be done through lubrication holes and groove on the inner ring or outer ring (for certain items) Operating temperature range is -30° to 80°C (-35° to 175°F)

NACHI Spherical Roller Bearings with suffix -V can be used for vibratory applications without retainer breakage (e.g., crushers, vibrating screens, etc.) NACHI's newly developed heat stabilization process can sustain normal function in operating temperatures of up to 200°C (392°F) with minimal dimensional changes and no reduction of bearing life. NACHI has adopted special radial clearance, controller tolerance (P6 on OD & P5 on Bore), and special care on retainer to suit these applications. Maximum permissible misalignment angle is approximately 2° under general service ...
