Decoding NTN 6012LLB
- 60Series
- Deep groove ball bearings, 60 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- LLBSuffix
- NTN suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6012 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
NTN 6012LLB measures 60 mm across the bore and 95 mm across the outside diameter; its width is 18 mm (60 x 95 x 18 mm).

For rotating equipment that needs reliable radial support and moderate axial capacity, deep groove ball bearings are a standard choice. The NTN LLB series comes with contact seals on both sides, which help keep lubricant in and contaminants out. You will find these bearings in electric motors, pumps, fans, conveyors and agricultural machinery, among other applications. MR Industrial Accessories supplies them and quotes by part number.
Reading the LLB code is straightforward: the basic number tells you the series and bore, while the LLB suffix confirms contact seals on both faces. For instance, 6008LLB is a 60 series bearing with a thin section and seals on both sides. 6208LLB belongs to the medium-section 62 series, and 6210LLB is the same series with a larger bore. This differs from variants with a single seal or with metal shields. These references cover common metric dimensions.
Typical uses include electric motors, centrifugal pumps, fans, conveyor belts, mixers, refrigeration equipment and agricultural machinery. In plants and maintenance workshops, they appear in food, chemical and petrochemical operations. The contact seals make them suitable for dusty, humid or splash-prone environments, as long as speed and operating temperature limits are respected.
When selecting an LLB bearing, review radial and axial loads, rotation speed, shaft diameter and ambient conditions. Contact seals offer good contaminant protection but create more friction than metal shields, so check that the permissible speed fits your application. During mounting, align the housings carefully, lubricate to specification and avoid impacts that could harm the seals or raceways.
LLB sealed bearings can be interchanged with equivalent references from other brands that use contact seals on both sides, such as 60, 62 and 63 series with suffixes like 2RS or 2RSH. Interchangeability depends on matching bore, outer diameter, width and sealing type. If you have a code from another brand or an unidentified part, MR Industrial Accessories can suggest a compatible alternative.

Frequently asked questions
- NTN 6012LLB bearing: what are its dimensions?
- NTN 6012LLB measures 60 mm across the bore and 95 mm across the outside diameter; its width is 18 mm (60 x 95 x 18 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6012.
- What does the LLB suffix mean on an NTN bearing?
- The LLB suffix means the bearing has contact seals on both faces. These seals retain lubrication and block dust and moisture, unlike metal shields that only cover without sealing.
- How do I choose between an LLB sealed bearing and an open one?
- If the equipment runs in a dusty, humid or splash-prone environment, an LLB seal is advisable. If speed is very high or continuous external lubrication is required, an open bearing may be better. Contact us by WhatsApp for advice.
- Can I replace an LLB bearing with one from another brand?
- Yes, as long as the main dimensions and sealing type match. The 60, 62 and 63 series with contact seals on both faces are equivalent. If unsure, send us the original part number and we will indicate the compatible alternative.
