The NTN LLU series deep groove ball bearing is a single row bearing with contact seals on both sides. It is designed to withstand moderate radial and axial loads, and is used in a wide variety of industrial and commercial applications. Its sealed construction retains lubricant and protects against contamination, making it suitable for dusty or humid environments. MR Accesorios Industriales sells this series with the NTN guarantee, a leading brand in bearings.

The LLU series designation is interpreted as follows: the numbers indicate the size and dimensional series (for example, 6008, 6208, 6210), while the LLU suffix indicates that the bearing has synthetic rubber contact seals on both sides. These seals are effective at retaining grease and excluding contaminants, unlike the LLB (non-contact seals) or ZZ (steel shields) suffixes. The 60 series is the lighter section, the 62 series is the medium section and the 63 series is the heavier section, which determines its load capacity.

In Argentine industry, LLU series deep groove ball bearings are used in electric motors, centrifugal pumps, fans, conveyors, machine tools and agricultural equipment. Their contact sealing makes them suitable for environments with dust, chips or moderate humidity, such as food plants, metalworking shops and rural establishments. They are also used in automotive applications, such as wheel bearings and transmission components, where reliability and low maintenance are required.

To correctly select an LLU bearing, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. Contact sealing offers greater protection but can generate somewhat more friction, so in high-speed applications it is advisable to evaluate non-contact seals. During mounting, ensure proper alignment between shaft and housing, and avoid striking the seals. Lubrication comes from the factory; if relubricating, use grease compatible with the original.

NTN LLU series bearings are interchangeable with those of other brands that follow the same standardized ISO dimensions. When looking for a replacement, verify the complete part number: for example, a 6208LLU may correspond to a 6208-2RS from another brand, as long as the dimensions and seal type match. MR Accesorios Industriales can advise you on the exact equivalence according to the original part number.
