Decoding NTN 7007CDLLB
- 70Series
- Angular contact ball bearings, 70 series. Series differ in outside diameter and width even when the bore is the same.
- 07Bore
- Bore 35 mm (07 × 5).
- CDLLBSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7007 is the standard ISO basic designation, which sets the bearing type, series and bore.

Angular contact ball bearings in the NTN 79 LLB series are built to carry radial and axial loads together, in one direction only. Their internal geometry gives the assembly the stiffness and running accuracy that machine tool spindles and measuring equipment demand. MR Industrial Accessories LLC supplies this series as part of its precision bearing range for customers in the United States and several Latin American countries.
Reading the code helps you confirm what you are ordering. The base number points to the size, and in that number the final two digits equal the bore diameter in millimeters divided by five. A CD marking means angular contact geometry with a 15° contact angle and a polyamide cage, while LLB covers the sealing or protection variant. So 7000CDLLB combines the 70 series, the CD layout and the LLB feature in one reference.
Typical duty for these bearings includes machine tool spindles, milling heads, measuring instruments, industrial robots and positioning systems, plus high-pressure pumps and compressors that need axial stiffness. High-speed capability also suits precision electric motors and grinding spindles.
Selection turns on four points: which way the axial load acts, internal clearance, lubrication and how the bearing is mounted. Pairs are the norm, with preload set to remove axial play and raise rigidity. The LLB seal keeps contaminants out and lubricant in. Shaft-to-housing alignment matters, because misalignment shortens service life. Manufacturer instructions for mounting and lubrication should be followed.
On interchangeability, bearings that follow the same international nomenclature, including SKF, FAG or NSK, can serve as equivalents as long as dimensions plus load and speed ratings line up. Contact angle and cage type are the details to check, since they differ between makers. The safest route is to give a specialist the complete original part number.

Frequently asked questions
- What does the 79 LLB designation tell me?
- The 79 is the dimension series, and its last digit ties to the bore diameter. LLB identifies the sealing or protection type. Where CD appears, as in the examples, it signals angular contact design with a 15° angle and a polyamide cage.
- Are these bearings mounted in pairs?
- Yes. Angular contact bearings such as the 79 LLB series are commonly paired, face-to-face or matched, so they take axial loads in both directions and stiffen the assembly. Preload should match the application.
- How do I request a quote for an NTN 79 LLB bearing?
- Send the complete part number, for example 7000CDLLB, by WhatsApp or email. We reply promptly with a quote. If the nomenclature is unclear, we can help identify the bearing.
