Double Row Deep Groove Ball Bearings
TFL supplies double row deep groove ball bearings for applications that require higher radial load capacity, improved bearing-position rigidity, and a compact bearing arrangement compared with standard single-row designs. This category focuses on metric 4200 and 4300 series double row ball bearing options, including models with bore sizes from 10 mm to 90 mm, open construction, chrome steel rings and balls, and ATN9 nylon cage configurations. Buyers can compare bore diameter, outside diameter, width, radial internal clearance, basic dynamic and static load ratings, permissible speed, lubrication status, and weight before requesting a quotation. These bearings are commonly used in gearboxes, pumps, conveyors, agricultural machinery, fans, reducers, material handling systems, and general industrial equipment where mounting space is limited but radial load capacity must be increased.

Double Row Deep Groove Ball Bearing Selection Guide
How to Choose This Bearing Type
Start by confirming whether the application needs more radial load capacity and stiffness than a standard single-row deep groove bearing can provide. Double row deep groove ball bearings use two rows of balls, allowing the bearing to support heavier radial loads while keeping the bearing arrangement compact. This bearing type is generally selected for mainly radial load conditions with limited to moderate axial load in both directions. If the application involves heavy axial load, high misalignment, high thrust requirements, or a defined contact-angle requirement, confirm the full bearing arrangement before choosing a replacement.Common Series and Model Range
The current product list covers 35 metric double row deep groove ball bearing configurations in the 4200 and 4300 series. Bore sizes range from 10 mm to 90 mm, with outside diameters from 30 mm to 160 mm and widths from 14 mm to 55 mm.| Selection Item | Current Product Range | What Buyers Should Check |
|---|---|---|
| Series | 4200 and 4300 series | Choose according to radial load capacity, bearing width, and housing space |
| Bore range | 10 mm to 90 mm | Match shaft diameter, mounting fit, and replacement dimensions |
| Construction | Double row deep groove ball bearing | Confirm radial load, axial load direction, rigidity, and space limitations |
| Material | Chrome steel rings and balls | Confirm load, speed, lubrication, temperature, and operating environment |
| Cage | Nylon cage, including ATN9 models | Check cage suitability for speed, temperature, lubricant, and application conditions |
| Lubrication | Standard lubrication status and selected W64 solid-oil options | Confirm maintenance interval, contamination level, lubricant retention, and relubrication access |
Open Design, ATN9 Cage, and W64 Options
The current product list is mainly built around open-type double row deep groove ball bearings. Open bearings are suitable when lubrication is supplied by the machine design or when the bearing position is protected from heavy contamination by the surrounding structure. ATN9 suffix models use a nylon or polyamide cage configuration and should be checked against speed, temperature, lubricant compatibility, and operating environment. Selected W64 models indicate a solid-oil lubrication option, which may be useful where lubricant retention, reduced maintenance, or limited relubrication access is important.Key Specifications to Confirm Before Quotation
For a quotation, provide the complete bearing number, bore diameter, outside diameter, width, required load rating, operating speed, shaft and housing fits, lubrication method, temperature range, operating environment, quantity, and any drawing or sample photos. Do not select only by bore size. For example, a 4208 ATN9 and 4308 ATN9 both have a 40 mm bore, but they differ in outside diameter, width, load rating, speed limit, and required installation space.

SKF / FAG / NSK Replacement Notes
Many buyers source double row ball bearings by SKF-style, FAG-style, NSK-style, NTN-style, or other brand-style numbers. TFL can help check replacement, alternative, cross-reference, or interchange options based on the complete designation, dimensions, suffixes, and application requirements.
Keep suffixes such as ATN9, CN, C3, W64, cage codes, lubrication codes, or seal-related codes in the inquiry. TFL does not claim that alternatives are original brand products or authorized replacements unless clearly stated.
Common Applications
Double row deep groove ball bearings are commonly used in gearboxes, pumps, conveyors, fans, agricultural machinery, material handling equipment, textile machinery, reducers, electric machinery, and general industrial equipment where higher radial load capacity is needed in limited space.
They are especially useful when the equipment requires compact bearing dimensions, smoother running, and better bearing-position rigidity than a single-row arrangement can provide.
Selection Insight
Double row deep groove ball bearings provide higher radial capacity than comparable single-row designs, but they should still be checked for speed, lubrication, cage material, fits, temperature, axial load conditions, and alignment. A dimensional match alone is not enough for replacement approval.
Popular Models / High-Demand Models
Popular models from this product list include 4200 ATN9, 4204 ATN9, 4205 ATN9, 4208 ATN9, 4212 ATN9, 4305 ATN9, 4308 ATN9, 4312 ATN9, and 4315 ATN9.
For a focused product page, 4208 ATN9 is a strong priority model because it has a common 40 mm bore and clear double row deep groove bearing positioning. 4308 ATN9 is also worth considering for buyers who need a wider bearing with higher load capacity in the same bore size range.
