An NTN part number can identify far more than basic bearing dimensions. Series, internal clearance, seals, shields, cage design, precision requirements and other suffixes can all affect whether a replacement is appropriate.
Start With the Existing Bearing Markings
If the bearing number is still readable, search the exact NTN part number first. Include prefixes and suffixes whenever possible. Codes such as C3, Z, ZZ, LLB and LLU may identify important construction or operating differences.
If the Part Number Is Missing or Unreadable
Tri-State Bearing can help narrow a replacement using the bearing type, bore, outside diameter, width, housing or mounting style, operating speed, load, temperature, lubrication, sealing needs and application.
- Measure bore, outside diameter and width as accurately as possible.
- Note whether the bearing is open, shielded, sealed or mounted in a housing.
- Record any remaining letters, numbers or manufacturer markings.
- Include the machine type and operating conditions when available.
- Send photos if the original bearing number cannot be identified.
NTN Cross References & Replacement Bearings

Manufacturer Interchanges
Ask us about potential NTN replacements for Timken, SKF, FAG, Schaeffler, NSK, Koyo, BCA, Fafnir and other industrial bearing brands.
Request an NTN Cross ReferenceVerify More Than Dimensions
A dimensional match does not always guarantee an equivalent bearing. Internal clearance, seals, lubrication, cage, precision, load rating, speed capability and fit should also be checked.
Browse NTN ProductsNTN Bearings for Industrial Applications
NTN products are used across a broad range of industrial equipment. The correct bearing depends on load, speed, shaft and housing fits, contamination, lubrication, temperature and required service life.
Electric Motors & Fans
Ball and roller bearings for motors, blowers, fans and rotating equipment where speed, noise, lubrication and internal clearance matter.
Conveyors & Material Handling
Mounted units, spherical roller bearings and other products for conveyor shafts, pulleys, take-ups and material-handling systems.
Pumps & Process Equipment
Industrial bearing options for pumps, compressors and process machinery requiring dependable radial or combined-load support.
Gearboxes & Power Transmission
Ball, cylindrical, tapered and spherical roller bearings for gear reducers and power-transmission equipment.
Food & Beverage Equipment
Mounted-bearing solutions intended for demanding washdown, contamination-control and food-processing environments.
Automation & Linear Motion
NTN Automation products including ball screws, linear ball bushings, shafting, actuators and linear-axis systems.

Frequently Asked Questions About NTN Bearings
Can I buy NTN bearings online from Tri-State Bearing?
Yes. Use the Tri-State Bearing NTN catalogto browse NTN products online. Product availability and pricing may vary by item and account status.
Can Tri-State Bearing help cross-reference another bearing brand to NTN?
Yes. Provide the existing manufacturer and part number whenever possible. Our team can help compare potential NTN replacements and review important specifications before substitution.
What does C3 mean on an NTN bearing?
C3 identifies an internal-clearance class greater than normal clearance. Internal clearance is an important operating specification and should not be changed solely because another bearing has the same dimensions.
What is the difference between open, shielded and sealed NTN bearings?
Open bearings expose the rolling elements, shielded designs use metal shields, and sealed designs use sealing elements to help limit contamination and retain lubricant. The appropriate design depends on speed, contamination, lubrication and application requirements.
How do I identify an NTN bearing if I cannot read the part number?
Measure the bore, outside diameter and width, note the bearing style and seals or shields, and record the machine or application. Photos and remaining markings can also help. Contact Tri-State Bearingfor assistance.
Where can I find NTN bearing catalogs and technical PDFs?
The technical resource library above includes NTN catalogs for ball and roller bearings, mounted units, spherical roller bearings, precision bearings, plummer blocks, linear motion products and other NTN product families.
