Flanged Deep Groove Ball Bearings
TFL supplies flanged deep groove ball bearings for compact assemblies that require simple axial location and stable radial support. This product list covers 199 single-row flanged ball bearing configurations in metric and inch sizes, including open, shielded, and sealed options. Buyers can compare bore diameter, outside diameter, width, flange outer diameter, flange thickness, stainless steel ring and ball materials, cage material, radial clearance, load rating, speed, lubrication, and weight. These bearings are commonly used in robotics, automation equipment, guide rollers, small motors, instruments, packaging machinery, conveyors, and precision mechanisms. TFL can help source standard or custom flanged deep groove ball bearing options based on model number, drawing, sample, or application requirements.

How to Choose This Bearing Type
Start with the shaft diameter and available housing space, then confirm whether the flange is needed to locate the bearing against a plate, shoulder, roller, or compact housing. The flange helps simplify assembly and reduce the need for a separate locating shoulder, but it should still match the housing design and axial locating direction. For replacement projects, do not select by bore size alone. Confirm the complete bearing number, outside diameter, width, flange outer diameter, flange thickness, seal type, load rating, speed, lubricant, and operating environment. If the flange dimension is wrong, the bearing may fit the shaft but fail to locate correctly in the assembly.Common Series and Model Range
This product list includes 199 flanged deep groove ball bearing configurations, with 151 metric models and 48 inch-size models. Metric bore sizes range from 1 mm to 30 mm, while inch bore sizes range from 0.04 inch to 0.625 inch.| Selection Item | Current Product Range | What Buyers Should Check |
|---|---|---|
| Measurement system | Metric and inch sizes | Match shaft size, housing bore, and drawing dimensions |
| Flange dimensions | Flange outer diameter and flange thickness listed by model | Confirm plate thickness, housing shoulder, and axial locating space |
| Closure type | Open, shielded, and sealed options | Balance friction, contamination protection, grease retention, and speed |
| Material | Stainless steel rings and balls in the listed range | Confirm corrosion exposure, lubricant, and required material grade |
| Clearance | CN clearance in the current product list | Check fit, temperature, speed, and running clearance requirements |
| Typical series | W 60, W 62, W 63, W 617, W 619, WBB, and D/W R inch series | Use the complete number, not only the basic bearing size |
Open vs ZZ vs 2RS Selection
Open flanged bearings are suitable when low friction and easy lubrication access are more important than contamination protection. They are often used in cleaner mechanisms or assemblies where the bearing is protected by the surrounding structure. ZZ or 2Z shielded flanged bearings provide basic protection against larger particles while keeping friction relatively low. They are commonly selected for guide rollers, instruments, small motors, and automation equipment where moderate protection and higher speed are both important. 2RS or 2RS1 sealed flanged bearings provide better grease retention and protection against dust or light contamination. They are useful in compact equipment where maintenance access is limited, but seal friction and operating speed should be checked before selection.Key Specifications to Confirm Before Quotation
For an accurate quotation, provide the complete bearing number if available. If the model is unknown, provide bore diameter, outside diameter, width, flange outer diameter, flange thickness, open / ZZ / 2RS preference, load, speed, operating temperature, corrosion environment, quantity, and any drawing or sample photos. For custom flanged deep groove ball bearings, flange diameter, flange thickness, corner radius, material, lubrication, packaging, and tolerance requirements should be confirmed before sourcing. Small dimensional differences can affect assembly fit in compact housings and rollers.SKF / FAG / NSK Replacement Notes
Many buyers search flanged bearings by SKF-style, FAG-style, NSK-style, EZO-style, or other brand-style numbers. TFL can help check replacement, alternative, cross-reference, or interchange options based on the complete designation and drawing dimensions. Brand-style numbers should not be shortened during inquiry. Suffixes such as R, F, MF, ZZ, 2Z, 2RS, 2RS1, and stainless material codes can change flange design, sealing, material, and width. TFL does not claim that alternatives are original brand products or authorized replacements unless clearly stated.Common Applications
Flanged deep groove ball bearings are commonly used in robotics, automation equipment, guide rollers, pulleys, conveyors, small motors, instruments, medical devices, packaging machinery, office equipment, laboratory equipment, and compact mechanical assemblies. The flange is especially useful where the bearing must be located in a thin plate, small roller, or compact housing without machining a complex shoulder. For higher axial loads, impact loads, or misalignment, the complete mounting design should be reviewed before selecting the bearing.Selection Insight
A flanged bearing is not the same as a flange bearing unit. This product type has an integral flange on the outer ring for positioning. It still needs correct shaft fit, housing fit, alignment, lubrication, speed, and load confirmation.
