    Shenzhen ZHAOWEI Machinery & Electronics Co., Ltd is a professional manufacturer of precision gear reducer. With many years of practical experience, our engineers analyze and share the reasons and solutions of hardened tooth surface gear reducer damage to the customers.

 Bearing Choice: Ball bearings are typically specified in applications where high radial and axial shaft loads are present. Be advised, however, that using ball bearings can increase audible noise in some cases. Please refer to the gearhead datasheet for shaft loading specifications. Sintered bearings are available for lower torque applications characterized by lower radial shaft loading and constant load characteristics. Ceramic bearings are an alternative for cost-sensitive applications in which extended life and enhanced radial load-bearing capabilities are important. MicroMo and the FAULHABER Group have developed a proprietary series of ceramic sleeve bearings. These bearing systems allow the user to increase radial loads beyond the levels allowed in traditional sintered bronze bearing systems. Costs of the ceramic bearings are also considerably below that of ball bearings.

Care should be taken when press fitting components to a gearhead output shaft. We recommend not exceeding the press fit force ratings specified in the gearhead datasheet. This can damage the bearings and the internal gears themselves. In some cases, gearhead shaft bearings (ball bearings only) are preloaded with a small wave washer under the retaining ring on the bearing. Exceeding the press fit force specification on the datasheet can damage this wave washer and negate the preload on the bearing. This will effect the performance of the bearing and should always be avoided.
