The main utility of flanged bearings is that they hold the bearings in position and protect them from air, dust, water and other impurities. The flanged bearings support the load transferred from the bearing shaft through the bearing. These bearings are available in two-, three- or four-hole configurations.

The flanged bearings perform vital functions in a wide variety of industries like aerospace, construction, industrial, mining, energy and oil industries. Depending on your application needs, you can buy flanged roller bearings or flanged ball bearings for standard applications. You can also buy a flanged plastic bearing, bronze-flanged sleeve bearing, flanged radial bearing, flanged linear bearing and flanged harrow bearing for special applications. Flanged bearings come in a variety of materials, such as cast iron, polymer or stainless steel.

Some important parameters you must consider before you buy flanged bearings are:

1. The magnitude and the type of load on the flanged bearings
2. The operating life and the reliability of the bearing system
3. The rotation speed, temperature and lubrication required
4. The vibration, mounting and maintenance of the component

The best contacts and resources to help you get it done

Buy flanged bearings from a reliable flanged-bearings manufacturer

Once you understand your requirements, go to a specific manufacturer to buy suitable flanged bearings.

I recommend: Rexnord Industries is a reputable manufacturer of flanged bearing, cylindrical roller bearing, and flanged sleeve bearing models as well as a range of flanged ball bearings especially for use in power transmission and conveying equipment and aerospace components. Pacific Bearing is another manufacturer that produces flanged ball bearing, flanged plastic bearing and linear sliding bearing designs. You can also buy four-bolt square-flanged units, two-bolt and three-bolt flanged units, two-bolt oval flanged units, four-bolt round flange units and flange bracket units from ABT. You can buy a flanged ball bearing, a plastic flanged bearing or a flanged spherical bearing at WM Berg.

Buy flanged bearings from distributors

Compare flanged bearings based on their features and prices at distributors' websites.

I recommend: MSC Industrial Direct is a reputable industrial retailer that also supplies flanged bearings. VXB Bearings is a distributor of flanged bearings of ceramic, ball and linear bearings grade.

Customize your flanged bearings according to your needs

If standard flanged bearing units available with flanged bearing companies do not meet your application requirements, try buying a customized flanged bearing

I recommend: Metallized Carbon Corporation is a manufacturer of custom made flanged bearings in special materials, for use in high temperature, high humidity and other special applications. igus Inc. is another manufacturer of standard and custom-made polymer bearings and spherical bearings. You can also customize your flanged bearing at Misumi USA.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Lubricate flanged bearings at regular intervals as suggested by manufacturers.
• •  Try using a polymer flanged bearing, as it is a low cost, more durable, silent and high load capacity bearing option.
• •  Make sure foreign particulates do not enter the bearing as they may cause damage to the bearing.
