How to read NTN 6008LLB
- 60Series
- Deep groove ball bearings, 60 series. For the same bore, each series has a different outside diameter and width.
- 08Bore
- 40 mm bore: 08 × 5.
- LLBSuffix
- NTN suffix: it defines the variant (sealing, cage, internal clearance or other features).
6008 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

The deep groove ball bearing is the most widely used component for supporting radial and moderate axial loads in rotating equipment. The NTN LLB series incorporates contact seals on both sides, which retains lubricant and blocks the entry of contaminants. It is used in electric motors, pumps, fans, conveyors and agricultural machinery, among many other applications. At MR Accesorios Industriales we quote it with the exact part number you need.
The LLB series designation is read by the basic number and the sealing suffix. For example, 6008LLB corresponds to a bearing of the 60 series —thin section— with contact seals on both faces; 6208LLB belongs to the 62 series, medium section, and 6210LLB to that same series with a larger bore diameter. The LLB suffix indicates contact sealing on both sides, unlike other variants with a single seal or with metal shields. These references cover a range of metric dimensions widely used in Argentine industry.
Typical applications of these bearings include electric motors, centrifugal pumps, fans, conveyor belts, mixers, refrigeration equipment and agricultural machinery. In Argentine industry they are found in food, chemical and petrochemical plants, and in maintenance workshops that repair rotating equipment. Their contact sealing makes them suitable for environments with dust, humidity or splashes, provided the speed and operating temperature conditions are respected.
To correctly select an LLB bearing, consider radial and axial load, rotation speed, shaft diameter and environmental conditions. Contact sealing offers good protection against contaminants, although it generates somewhat more friction than metal shields; therefore it is recommended to verify that the maximum permissible speed is compatible with the application. During mounting, it is essential to align the housings well, lubricate according to specification and avoid impacts that could damage the seals or the raceways.
Deep groove ball bearings with LLB sealing can be interchanged with equivalent references from other brands that use contact seals on both faces, such as the 60, 62 and 63 series with suffixes 2RS, 2RSH or similar. Interchangeability depends on the main dimensions —bore, outer diameter and width— and the type of sealing matching. If the customer brings a code from another brand or an unidentified part, at MR Accesorios Industriales we indicate the compatible alternative.

Frequently Asked Questions
- What are the dimensions of the NTN 6008LLB bearing?
- The NTN 6008LLB bearing has a 40 mm bore, a 68 mm outside diameter and a 15 mm width (40 x 68 x 15 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6008.
- What does the LLB suffix mean in an NTN bearing?
- The LLB suffix indicates that the bearing has contact seals on both faces. These seals retain lubrication and protect against the entry of dust and humidity, unlike metal shields that only cover without sealing.
- How do I choose between an LLB sealed bearing and an open one?
- If the equipment works in an environment with dust, humidity or splashes, an LLB seal is advisable. If the speed is very high or continuous external lubrication is required, an open one may be better. Consult us by WhatsApp and we will advise you.
- Can I replace an LLB bearing with one from another brand?
- Yes, as long as the main dimensions and the type of sealing match. The 60, 62 and 63 series with contact seals on both faces are equivalent. If you have doubts, send us the original part number and we will indicate the compatible alternative.
