Shields or seals are often installed to retain lubrication and to prevent contamination from entering the bearing. While a shield contacts the outer ring and does not meet the inner ring, the seal generally encounters both the inner and outer rings. Torque or drag is lower with a shield than with a seal. Alternately, the seal provides a higher degree of protection from contamination. Shields and seals are available in a variety of materials and configurations. Please contact Power Transmission Specialties, Inc. for technical assistance with any special requirements.

Bearing noise is a function of both the bearing and the way it is used. Bearing noise is not generally influenced by ABEC, and there is no fixed standard among bearing manufacturers for acoustic noise. Some external factors that affect bearing noise include lubricant type, excessive bearing load, and improper installation.

Between -100 deg. F to 375 deg. F for continuous operation using standard bearings.

1. Find the bearing load and load capacity First, know the type and amount of bearing load that your application will place on the bearing. Small-to-medium-sized loads usually work best with ball bearings. Heavy load applications usually work best with roller bearings. 2. Know the rotational speed of our application Determine the rotational speed of your application. High speeds (RPM) usually work best with ball bearings, and lower speeds usually work best with roller bearings. 3. Factor in bearing runout and rigidity You also want to determine what kind of runout your application will allow. If the application allows only small deviations to occur, then a ball bearing is most likely your best choice. 4. Find the right lubrication for your bearings needs For high-speed applications, calculate your n*dm value, and if it’s higher than the grease max speed, then the grease won’t be able to provide sufficient lubrication. There are other options like oil misting. For low-speed applications, an oil bath is a good choice.
