Flanged ball bearings have a lip extension on the outer ring. This flange can facilitate mounting and positioning in a housing. Flanged ball bearings are available open, shielded or sealed. These inch and metric sized deep groove radial flanged ball bearings can bear heavy radial loads and moderate thrust loads in both directions. These flange ball bearings can be inserted into a hole matching the OD of the bearing. The flange limits flanged ball bearings from sliding through the hole by bottoming out against the flat surface. The following flanged ball bearing catalogue provides complete flange bearing data, including the flange bearing size chart, price inquiry as well as CAD drawings for free download.
Flange bearing types are radical. Although flanged on one side, these flanged ball bearings are still radial deep groove ball bearings and they can carry the major radial loads. Flanged ball bearings are considered as series of radial ball bearing with flange.
Chrome steel is the most common material for flanged ball bearings because it has characteristics of high load capacity and low noise. When there is a need for rust prevention, 440c stainless steel material is usually used.
Such kind of stainless steel material can bear both high load and high speed. Furthermore, it has the function of rust prevention. Therefore, stainless flange bearing series are considered to be powerful. For higher speed requirements, silicon nitride ceramic balls are used to take the place of traditional steel balls.
Factors to be considered when choosing an ABEC grade include radial and axial runout requirements, bore and OD fits, and the audible noise level. Lily Bearing offer these types of grades which show the available selection of bore and OD size tolerances, and the radial runout limits for each. ABEC of Grades 3 is the first choice for routine applications. Typically, race finish and race geometry are superior in ABEC 5 and higher. These grades are generally recommended for precision assemblies where low noise, minimal runout, and long life are important considerations for flanged ball bearings.
Bore Dias of flanged ball bearings in metric size range from 1mm to 50mm. Bore Dias of flanged ball bearings in inch size range from 0.04688" to 0.375".
Most of our chrome steel miniature flanged ball bearings can be supplied open or with metal shields. Flanged bearings with the larger sizes may be available with rubber or Teflon contact seals or low friction non-contact rubber seals.
Bearing with flange series have a solid steel flange on the outer ring. This allows the flanged ball bearings to be more easily located in a housing. The flange can also help to prevent axial movement of the ball bearing in the event of a thrust load on the bearing.
Miniature flanged ball bearings with extended inner ring are specially designed to replace the need for additional locational flange in applications.
Flanged Ball Bearings include metric flanged ball bearing series and inch flanged ball bearing series.
Crown type cages: The stainless steel pressed cage is inner ring guided. It shows excellent performance in low torque, low speed applications.
Ribbon type cages: Consists of two mating steel pressings, the cover side and the finger side. Usually guided by the rolling elements and designed to reduce frictional torque.
A one-piece crown cage is more common for the smallest and the thinnest bearings due to space constraints. Larger sizes have a two piece ribbon cage.
Open flanged ball bearings are supplied with a light oil lubrication. Shielded or sealed flanged ball bearings are usually supplied with grease lubrication but shielded flanged ball bearings can be offered with instrument oil for low speed, low friction applications. Thanks to our in-house relubrication facility, these flanged ball bearings can be offered with customer specified oils, greases or dry lubricants.
The standard instrument used for the noise testing of flanged ball bearings is the Anderon Meter (sometimes called Anderometer) made by Sugawara Laboratories. This measures noise with an accelerometer contacting the outer races of the flanged ball bearings while the inner race of the flanged ball bearings is rotated at 1800 RPM.
Normal chrome steel flanged ball bearings can be used at constant temperatures of 120°C or intermittent temperatures of up to 150°C. Above these temperatures, the load capacity of the chrome steel will be reduced. By means of special heat treatment processes and the addition of high temperature grease, we can also customize flanged ball bearings for high temperature resistance.
Internal clearance is the play between outer ring, inner ring and rolling element. Generally, the amount of up and down movement of the outer ring with respect to the fixed inner ring is called the radial internal clearance and its right and left movement the axial internal clearance. The internal clearance of Flanged ball bearings in operation is an important factor that has a significant influence on other factors such as noise, vibration, heat and fatigue life.
Flanged ball bearings are widely used in many applications. Some typical applications are as follows:
Food Processing Machinery Conveyors Material Handling
Belt Drives in HVAC Textile Machines Baggage Systems
Medical Processing Scanner Motors Stepping Motors
Rotary Encoders Card Readers
