Stainless Steel Flange Mounted Bearings
Stainless steel flange mounted bearings are engineered to provide shaft support for radial and thrust loads in a variance of applications. Our stainless steel flange mounted bearings are manufactured from an array of stainless steel grades to bring you the best performing and anti-corrosive bearing available. We stock to bolt pillow block, tapped base, four-bolt flange, to bolt flange, piloted flange, and stainless steel take-up bearings in inch and metric shaft sizes.
Stainless Steel Mounted Bearing Materials
Our stainless steel flange mounted bearings are designed with features such as a solid base which eliminates crevices, where contaminates, can gather, special seals to ensure a long seal-life with the bearing, and an array of additional features that prolong the bearing life and increase performance capabilities. Stainless steel flange mounted bearings are found in a range of applications including food processing, high and low-temperature applications, and applications with highly abrasive conditions. Combining different grades of high-quality stainless steel such as 302, 304, and 440C to create an industry-leading quality and performance bearing with optimal corrosion resistance. The operating temperature of stainless steel bearings range from -10°F up to 250°, for additional information or to get a quote contact our customer support team and we will be happy to assist you!
Stainless Steel Flange Mounted Bearing Housing Types
The below sketches are our standard housing types ranging from two-bolt pillow blocks and flanges to takeup frames and hanger flanges.
The below shows our standard stainless steel mounted bearing nomenclature, the nomenclature varies slightly across different brands but the bearings that match dimensionally do interchange with each other. For assistance with identifying your bearing or interchanging please contact our customer support team and we will be happy to assist you!
The below interchange tables only show bearing interchanges from Mariner stainless steel bearings, we also supply brands such as IPTCI, KML, PII, AMI, FYH, Peer, Timken, Dodge, and many more!

Proper lubrication is essential to a bearings life, not only does it extend the life of the bearing but it also increases the working life of the unit.
Our bearings come pre-lubed from the factory with a 1/3rd grease fill with a food-grade grease. Because they come from the factory already lubricated you should not add grease to the unit until before placing it into service. Relubrication
Relubrication can be more necessary in certain applications than others to maximize the lifespan of the bearings. In the relubrication process, it is imperative to only add the amount of grease listed in the above table to prevent over-filling the bearing. The ideal grease filling is 1/3rd at all times. If the bearing becomes overlubricated and fully filled with grease it not only decreases the bearings life but also the limiting speed. Do not relubricate a bearing with more lubricant than listed on the above table unless the bearing is in an extremely dirty wet environment, avoid the common practice of pumping grease until you feel resistance or until lubricant is emitted from the bearing seal. Use the below chart for bearing relubrication intervals.

Load Rating Data
The load rating table below is to be used as a general tool for determining how loads and speeds imposed on a bearing will affect the overall life of the bearing. By determining your expected radial load and speech, you can figure out the L10 life that will be suitable for your application.
L10 hours are the number of service hours a bearing can be operated before 10% of the bearings fail. This means that the AVERAGE service life of a bearing (50% failure rate) will be higher than those listed below. Note:
Decreasing bearing loads will have an exponential effect of the fatigue life of a bearing.
The data below is based on radial load capacity for given life/speed (lbs.)
X = Past limiting speed for standard seal bearingsBearing Fatigue Life
BEARING LIFE INFORMATION:
If a bearing is correctly mounted, lubricated, sealed from contaminants, installed properly, and handled accordingly, the only only other thing that can cause failure is fatigue of the material. Metal fatigue is the progressive and localized structural damage that occurs when a material is subjected to cyclic loadings.Bearing Fatigue Life
The life of a bearing is defined as the hours of operation (at a constant speed) that the bearing is capable of running before evidence of fatigue develops in the material of the raceways or in the rolling elements of the bearing.
Calculating Bearing Life:
is the number of hours (at a constant speed) that a group of bearings will run before 10%
of the bearings fail.
Bearing life formula :
: The above formula assumes that the bearings are being ran in ideal operating conditions (including press-fit). Considering that typical mounted bearing applications have a flip fit, a derating factor multiplier should be used to calculate L10
life.- For set screw and eccentric collar bearings, a multiplier of 0.456 should be used. - For tru-loc bearings, a multiplier of 0.800 should be used.
Certain applications require different L10
life conditions. An application that is NOT
used frequently will require lower L10
life hours to give sufficient performance than an application that IS
frequently used and requires higher reliability. L10 Life Chart
The data below is the Cr/P Factor for the stated RPM
The limiting speed of a bearing is greatly affected by the fit between the bearing bore and shaft. The values listed in the Limiting Speed Table
below are based on ideal mounting conditions, which would include a press fit between the bearing and the shaft. For normal mounting conditions, like the shaft tolerances listed below, the listed maximum speed can be reduced by up to 25%
. If your shaft does not fall into the listed tolerances, your maximum speed may be significantly lower than the listed speeds.
