62301 vs 62201: Wide Deep Groove Bearings With 12 mm Bore
The 62301 bearing measures 12 mm bore by 37 mm OD by 17 mm width, while the 62201 bearing measures 12 mm bore by 32 mm OD by 14 mm width. Selecting wide deep groove bearings 12 mm bore requires checking both the outer housing diameter and the axial cavity, as identical bore sizes do not guarantee dimensional interchangeability.
In industrial machinery across Indonesia - from conveyor drives in Cikarang plants to pump assemblies in Surabaya workshops - ordering by inner diameter alone frequently leads to costly installation delays. The 62300 and 62200 series utilize different width and diameter standard ratios under ISO standards[1].
Understanding these dimensional differences prevents purchasing errors and ensures your equipment receives the exact bearing envelope required for smooth operation.
What are the exact dimensions of 62301 and 62201 bearings?
The 62301 bearing measures 12 mm bore by 37 mm OD by 17 mm width, while the 62201 bearing measures 12 mm bore by 32 mm OD by 14 mm width. These two components belong to separate dimension series designed for different physical envelopes and load profiles.
The 62201 2RS variant features dual rubber seals under the premium HI-TEC SILVER brand, whereas the 62301 is available as an open variant. The rubber seals on the 62201 2RS retain grease and prevent contamination from dust and moisture, making it ideal for enclosed automotive or manufacturing drives. Conversely, the open 62301 variant relies on external lubrication systems within sealed gearboxes or oil-bath machinery.
| Part Number | Bore (d) | Outside Diameter (D) | Width (B) | Series | Available Variant | Brand Tier |
|---|---|---|---|---|---|---|
| 62301 | 12 mm | 37 mm | 17 mm | 62300 | Open | Standard HI-TEC |
| 62201 | 12 mm | 32 mm | 14 mm | 62200 | 2RS (Dual Rubber Seal) | HI-TEC SILVER |
Both parts share the ISO standard '01' bore designation indicating a 12 mm inner diameter[1]. However, the additional width and larger external diameter of the 62301 provide expanded space for larger rolling elements, directly increasing dynamic load capacities[2]. Selecting between these options requires verifying housing clearance and environmental exposure. Explore our deep groove ball bearing choices to evaluate different seal and design configurations.

Are 62301 and 62201 wide deep groove bearings interchangeable?
Bearings sharing a 12 mm bore are not interchangeable, as outside diameter and width differ significantly between the 62300 and 62200 series. Substituting a 62201 for a 62301 will result in a loose fit in a 37 mm housing bore and create 3 mm of endplay in a 17 mm shaft cavity.
A technician in a Bandung textile mill or a Jakarta repair shop cannot rely on bore size alone when sourcing replacement parts. Mechanical housings are machined to precise tolerances; inserting a 32 mm OD bearing like the 62201 into a seat intended for a 37 mm OD 62301 causes immediate alignment failure and machine downtime.
- Bore Matching: Both parts fit a 12 mm shaft, but shaft fit is the only shared dimension[2].
- Housing Diameter: The 62301 requires a 37 mm housing bore, whereas the 62201 requires a 32 mm housing bore[2].
- Axial Width: The 62301 requires 17 mm of shaft length, compared to 14 mm for the 62201[2].
- Sealing Requirements: The 62201 2RS comes pre-lubricated with dual rubber seals, while the open 62301 requires external lubrication.

Frequently Asked Questions
What are the exact dimensions of 62301 and 62201 bearings?
The 62301 bearing measures 12 mm bore, 37 mm outside diameter, and 17 mm width. The 62201 bearing measures 12 mm bore, 32 mm outside diameter, and 14 mm width.
Why do 62301 and 62201 bearings have different widths despite having a 12 mm bore?
They belong to different ISO dimension series. The 62300 series utilizes a wider profile and larger outside diameter than the 62200 series to handle different space envelopes and load requirements.
Are 62201 2RS and 62301 bearings interchangeable?
No, they are not interchangeable. The 62301 is 5 mm larger in outside diameter and 3 mm wider than the 62201 2RS, meaning neither will fit into the other's housing or shaft cavity.
How do I check pricing and availability for 62301 and 62201 2RS bearings?
You can verify current stock availability and pricing directly by contacting HI-TEC ASIA on WhatsApp at +62 823-1004-6527.
