BEARING

NACHI BEARING making the best use of our own high quality material and heat treatment/grinding technology developped in our cutting tools production. Its technology that enables long-life, high speed, high accuracy and compactness keeps evolving further and plays an active part in various fields beginning with automotive in Thailand. NACHI BEARING is contributing for the improvement of reliability.

Deep Groove Ball Bearing

Main product with biggest volume in rolling bearing.Ball and Raceway contact on point, and semidiameter of circular arc of raceway is slightly bigger than the one of ball. Easy structure to endure combination of Radial and Axial load with high accuracy is appropriate also for rapid rotation.

Combination Angular Contact Ball Bearing

Normally Single Row Angular Contact Ball Bearings are used as a combination of two or more bearings. There are three types of combinations such as back to back(DB),face to face(DF) and tandem(DT), and clearance of matched set are already adjusted. If high accuracy is required such as machine tool spindles (JIS/ISO class 5 or higher), it is used with preload.

SPHERICAL ROLLER BEARING

The spherical raceway of outer rings are manufactured and assembled focusing to the center of bearings. Barrel type rollers and cages are assembled with inner rings. NACHI Spherical Roller Bearings are suitable for high axial, impulse and heavy load applications such as paper machine, rolling mill and other large size machineries.

Single Direction Thrust Ball Bearings

Thrust ball bearings are designed to handle axial loads only. It consists of ball, retainer and both shaft and housing washers which contain grooves for the ball. The Double-direction Thrust Ball bearings can support bi-directional loads.The bearings with spherical housing washer can prevent static misalignment. Applying polyamide cage improved its silence.

Double-direction Thrust Ball Bearings

Carrying axial loads in both directions. This Bearing consists of 3 kinds of grooved washer bearing rings, 2 kinds of cage and ball assembly. The bearings with spherical housing washer can prevent static misalignment.

Double-direction Thrust Angular Contact Ball Bearings TAD series

Double-direction Thrust Bearing used in machine tool spindle. High contact angles carry high axial loads.

Spherical Roller Thrust Bearings

Adopting large diameter roller provides world's largest class of high capacity. Adopting high cleanliness steel enables longer life. The optimisation of cage shape reduces sliding friction of cage and the optimisation of operating cage position controls increasing temperature to the minimum. Especially it significantly reduces increasing temperature at grease lubricating.
