production of computer motherboards. Advantages: These chemically resistant bearings have been specially designed to facilitate simplicity in construction, keeping costs down.

Advantages: Because of the use of plastic in the construction of the inner and outer bearing races, tight tolerance is not required.

Plastic ball bearings made of PPS, PEEK or PI with glass balls can be used in high temperature applications such as drying plants, pass through type furnaces or sterilizers.

Advantages: These chemically resistant bearings have been specially designed to facilitate simplicity in construction, keeping costs down. Flanged plastic ball bearings are extremely smooth running when used in conveyor roller operations. Advantages: Because of the use of plastic in the construction of the inner and outer bearing races, tight tolerance is not required. The fl anged plastic bearing will easily be fi tted into the pipe with a light press fi t vs. the normal tolerance associated with metal bearing used in the same application. Plastic ball bearings made of PPS, PEEK or PI with glass balls can be used in high temperature applications such as drying plants, pass through type furnaces or sterilizers. Advantages: The PI material is capable for temperatures to 250 C without lubrication. Even in diffi cult conditions such as extreme humidity or steam, these bearings are suitable for continuous high temperature use. Full-complement plastic ball bearings Advantages: Increase of the maximum bearing capacity. No cages (ball retainers) will be required. Берг АБ bergab@ya.ru Тел. (95) , факс (95)

Other materials may have different tolerances. Assembly instructions (Radial Ball Bearings) We recommend a press fi t on the ID and a loose fi t on the OD (or the reverse is also okay). This will compensate for any growth of the shaft or hou sing. However, a press fi t on the ID AND OD, or a too tight press fi t on the ID OR OD will reduce or eliminate the radial clearance and may cause the bearing to fail. For a press fi t on the ID, the shaft should be 0.02 mm larger than the bearing inner diameter. For a press fi t on the OD, the hou sing bore should be 0.02 mm smaller than the bearing OD. If you should like help to calculate these values, please contact SMG for technical support. Radial bearing clearance Bore Radial bearing clearance d [mm] [µm] more than up to min. max These data are standard values for our radial bearings. The bearing clearance can be changed according to customer s order. 9 Берг АБ bergab@ya.ru Тел. (95) , факс (95)
