Deep Groove Ball Bearings 1.4in Bore — Dimensions & Load Ratings
When sourcing deep groove ball bearings 1.4in bore sizes for your equipment, getting the exact dimensions and ratings is critical for performance and longevity. These 1.4″ shaft ball bearing options are built to precise tolerances, ensuring a perfect drop-in fit for standard US industrial applications.
Sizing and Load Tolerances
A 1.4 inch inner diameter bearing must balance envelope space with structural strength. The outer diameter (OD) and width vary depending on whether your application requires a light, medium, or heavy-duty series. These dimensions directly dictate the bearing load capacity and RPM limits.
- Inner Diameter (ID): 1.400 inches (35.56 mm) – engineered for a precise press-fit on standard shafts.
- Outer Diameter (OD): Varies by series (e.g., light-duty vs. heavy-duty housing requirements).
- Width: Optimized to handle combined radial and moderate axial loads without flexing.
| Bearing Series | Bore (ID) | Typical Outer Diameter (OD) | Typical Width | Dynamic Load ($C$) | Static Load ($C_0$) |
|---|---|---|---|---|---|
| Light Duty | 1.400″ | 2.440″ | 0.551″ | 3,600 lbs | 2,300 lbs |
| Medium Duty | 1.400″ | 2.834″ | 0.669″ | 5,800 lbs | 3,650 lbs |
| Heavy Duty | 1.400″ | 3.149″ | 0.826″ | 7,400 lbs | 4,500 lbs |
Speed Ratings: Grease vs. Oil Lubrication
The high speed performance of a radial ball bearing depends heavily on your choice of lubricant. High rpm applications generate friction heat, making the limiting speed a crucial spec to watch during installation.
- Grease Lubrication: Offers a lower maintenance profile. Ideal for shielded ball bearing 1.4 bore setups, topping out at roughly 8,500 RPM for standard single row configurations.
- Oil Lubrication: Best for continuous-bath or mist systems. Lowers low friction coefficients further, allowing the same single row deep groove bearing to safely reach up to 11,000 RPM.
Shielded vs. Sealed 1.4-Inch Deep Groove Bearings
Choosing the right enclosure for your 1.4 inch inner diameter bearing determines how long it lasts and how well it performs in your equipment. Three primary enclosure configurations cover clean high-speed runs, contaminated outdoor duty, and oil-bath gearboxes.
Metal Shields (ZZ) for High-Speed Performance
If your application demands high rpm and low friction, a metal sealed ball bearing 1.4 bore (ZZ) is the ideal choice — see also our sealed deep groove ball bearings range for broader 2RS catalog options.
- Design: Non-contact steel shields pressed into the outer ring.
- Best For: Clean environments where retaining grease and minimizing torque are the top priorities.
- Advantage: Allows for maximum high speed performance without generating excess heat.
Rubber Seals (2RS) for Maximum Protection
For harsh conditions where dust, dirt, and moisture are constant threats, we recommend our rubber sealed 2RS bearing.
- Design: Heavy-duty, contact rubber seals (including optional triple lip seals) that physically brush against the inner ring.
- Best For: Outdoor equipment, electric motors exposed to the elements, and dusty workshop floors.
- Advantage: Provides an airtight barrier that locks contamination out and keeps lubrication in.
Open Type Bearings for Oil-Bath Systems
Open bearings have no built-in shields or seals, leaving the single row deep groove bearing components fully exposed.
- Design: Completely open faces allowing free flow of external lubricants.
- Best For: Enclosed gearboxes and continuous oil-bath lubrication systems.
- Advantage: Easiest to maintain and service when part of a larger, self-lubricating mechanical system.
| Bearing Type | Friction Level | Dust/Moisture Protection | Top Speed Capability |
|---|---|---|---|
| Metal Shielded (ZZ) | Ultra-Low | Moderate | Excellent |
| Rubber Sealed (2RS) | Moderate | Maximum | Good |
| Open Type | Lowest | None (Requires Housing) | Maximum |
Material Choices for 1.4in Bore Bearings
These deep groove ball bearings 1.4in bore options using premium materials tailored to your specific operating conditions. Choosing the right material ensures long-term reliability and keeps your equipment running without unexpected downtime.
Comparing Our 1.4″ Shaft Ball Bearing Materials
| Material Type | Best For | Key Benefit |
|---|---|---|
| High-Carbon Chromium Steel (GCr15) | Heavy-duty industrial wear | Maximum hardness and fatigue life |
| Stainless Steel | Wet or washdown environments | Excellent corrosion and rust resistance |
| Ceramic Hybrids | Extreme speeds & electric motors | Electrical insulation and low friction |
High-Carbon Chromium Steel (GCr15)
This is the standard choice for heavy-duty industrial applications. Bearing steel (GCr15) with stamped steel cages provides the hardness needed to withstand heavy radial loads at high speed performance levels. If your machines run daily under normal factory conditions, these offer the best balance of durability and value.
Stainless Steel Options
For food processing, marine, or chemical applications, high-grade stainless steel builds resist rust and chemical degradation — browse discount stainless steel deep groove ball bearings for mixed-size stainless programs.
Ceramic Hybrids
When you need high speed performance and low friction, ceramic hybrids are the top choice. Featuring chromic steel ball bearings races paired with silicon nitride ceramic balls, these bearings prevent electrical arcing in electric motors and handle much higher RPMs than standard steel.
Installing and Maintaining 1.4″ Shaft Bearings
Getting the most out of your deep groove ball bearings 1.4in bore setup comes down to proper installation and regular upkeep. Poor handling during installation is one of the leading causes of early bearing failure, but a few correct steps will keep your equipment running smoothly.
Proper Press-Fitting Without Damage
When mounting a 1.4 inch inner diameter bearing onto a 1.4″ shaft ball bearing assembly, always apply force to the face of the inner ring. Pressing on the outer ring forces the load through the balls, which dents the raceways and ruins the part before it even spins.
- Use the right tools: Use a press tube or installation sleeve that matches the inner ring dimensions perfectly.
- Check the fit: Ensure the shaft is clean, burr-free, and within specified tolerances.
- Avoid impact: Never strike the bearing directly with a standard hammer.
Warning Signs of Bearing Failure
Catching issues early saves you from expensive unexpected downtime. If industrial replacement bearings start showing these signs, it is time for a replacement:
| Failure Sign | Common Root Cause | What to Check |
|---|---|---|
| Excessive Noise | Contamination or lack of grease | Seal integrity |
| High Vibration | Misalignment or spalling on raceways | Shaft alignment |
| Overheating | Overloading or too much lubricant | Operating temperature |
Lubrication Intervals and Grease Selection
Proper lubrication keeps chromic steel ball bearings running quietly and reduces internal friction. For our sealed and shielded options, the correct grease volume is packed at the factory for maintenance-free operation. However, for open types or severe operating environments, keep these rules in mind:
- Choose the right grease: Use high-quality polyurea or lithium-complex greases for general electric motor and industrial applications.
- Don’t over-lubricate: Too much grease causes churning, which generates heat and degrades the lubricant. Fill the bearing housing housing to about 30% to 50% of its capacity.
- Set a schedule: Base your re-lubrication intervals on the operating temperature and high rpm demands of your specific machinery.

FAQs About 1.4″ Bore Deep Groove Ball Bearings
What is the metric equivalent of a 1.4-inch bore bearing?
A 1.4-inch inner diameter bearing equals exactly 35.56 mm. While standard metric bearings usually jump from 35 mm to 40 mm, we manufacture specialized inch-series deep groove radial ball bearings to fit this precise 1.4″ shaft diameter size perfectly without needing standard shaft modifications.
Can a 1.4in bore bearing handle axial thrust loads?
Yes. While a single row deep groove bearing is designed primarily for radial loads, its deep raceway grooves allow it to support moderate axial (thrust) loads in both directions. It handles these combined loads well even during high speed performance runs.
How do I find the part number for a replacement 1.4″ ball bearing?
Check the face of the outer ring or the shield for stamped markings. If the number is worn off, use a caliper to measure the inner diameter (1.4 inches), the outer diameter, and the width. Contact us with those dimensions, and our team will match you with the exact industrial replacement bearings you need for your equipment.
