The HOFFMAN 62300 is a single-row deep groove radial ball bearing designed for rotating shaft support in industrial machinery, motors, transmissions, pumps, and older OEM equipment.

Its nominal dimensions are:

Bore Diameter: 10 mm

Outside Diameter: 35 mm

Width: 17 mm

The defining feature of the 62300 format is its relatively wide 17 mm bearing section compared with many conventional deep groove bearings using a 10 mm bore. This thicker cross-section can be important in older equipment where the bearing width, shaft shoulder position, housing depth, and axial retention arrangement were designed specifically around the original bearing.

Deep groove ball bearings are primarily intended for radial loading, while also supporting moderate axial loads in both directions under suitable operating conditions.

The original Hoffmann bearing brand has historical roots in the United Kingdom. Genuine HOFFMAN / Hoffmann 62300 bearings found today may therefore be older production, unused warehouse stock, or New Old Stock (NOS).

For modern replacement, the dimensional reference 10 × 35 × 17 mm is particularly important. However, identical external dimensions alone do not guarantee complete interchangeability.

Before selecting a modern equivalent, verify:

• 10 mm bore
• 35 mm outside diameter
• 17 mm width
• Single-row deep groove construction
• Open, shielded, or sealed configuration
• Internal clearance
• Cage design and material
• Lubrication
• Load ratings
• Speed capability
• Shaft and housing fits

⚙️ Applications

• Legacy electric motors
• Industrial machinery
• Gearbox assemblies
• Pumps
• Mechanical transmissions
• Machine tools
• Agricultural machinery
• Conveyor equipment
• Industrial drive systems
• Restoration of older OEM machinery

Shaft Fit: Nominal 10 mm shaft; verify shaft tolerance and load condition

Housing Fit: Nominal 35 mm housing bore; verify housing tolerance and shoulder dimensions

Installation Consideration: The 17 mm bearing width must match the original housing depth, shoulder position, retaining arrangement, and available axial space

Historical Availability: Original Hoffmann bearings may be encountered as legacy inventory or New Old Stock (NOS)

Standard: Legacy / Manufacturer-Specific HOFFMAN Deep Groove Bearing Reference

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• HOFFMAN 62300
• Hoffmann 62300
• 10x35x17 mm Deep Groove Ball Bearing
• 10 mm Bore Ball Bearing
• 35 mm OD Ball Bearing
• 17 mm Wide Deep Groove Bearing
• Extra-Wide Single Row Ball Bearing
• Legacy Hoffmann Replacement Bearing
• Modern 62300-Series Bearing
• Industrial 10x35x17 Bearing

The 10 × 35 × 17 mm dimensions provide an excellent starting point for modern cross-reference work, and current manufacturers may offer bearings using the same dimensional envelope.

However, a modern bearing should not be considered 100% interchangeable from dimensions alone. The replacement should also match the required deep-groove construction, closure type, internal clearance, cage, lubrication, load rating, speed rating, precision, shaft fit, housing fit, and shoulder geometry.

For legacy machinery, retaining the full HOFFMAN 62300 reference together with the 10 × 35 × 17 mm dimensions gives the best basis for identifying an appropriate modern replacement.

(Always verify the original bearing construction and machine requirements before ordering a substitute.)
