Bearing retainer noise prevention:

1, bearing in high speed rotating, pocket of the big hole clearance bearing vibration amplitude maintains a far greater than the small clearances for hole retainer vibration amplitude, so the gap is especially important for hole values.

2, to make retainer revolution movement stability, should try to lead the way and pay attention to give rings lead the sufficient lubrication, under the condition of high speed of the tapered roller bearing structure to improve, will guide roller of L retainer to Z type of rings raised edge guide keep frame.

3, actively adopt advanced cleaning technology, to spare parts of the products after effective thoroughly clean, improve the bearing cleanliness.

4, should pay attention to try to minimize radial clearance.

5, and try to keep the price increase manufacture accuracy, improve maintains a surface quality and help to reduce the rolling body and maintains a collision or friction of the noise.

Bearing maintains a features:

Maintains a a injection molding, can obtain the precise geometrical shape and size accuracy, the surface is bright and clean and bright; Can realize a model more cavity injection molding, bearing assembly is convenient, the production efficiency is high, easy to realize automation.

 
Will the vacuum drying filament resin, plastic material in crowded in the cylinder, after resistance wire heating melting, with the aid of the piston or screw pressure, melt into the raw material from the nozzle state in injection molding machine installation on the special mold cavity inside, after heat preservation, after cooling get needs maintains a finished product.
