Deep groove ball bearing NTN 6301LLUCM/5K, Outer diameter: 37 mm | Width: 11 mm | Inner diameter: 12 mm

This single-row deep groove ball bearing from NTN was designed to ensure optimal performance under radial and axial loads. Thanks to the double-sided rubber seals, it provides effective protection against contaminants while maintaining moderate frictional resistance. The internal radial clearance in CM specification increases precision, reduces vibration and makes the bearing ideal for demanding industrial and mechanical applications.

Features:
This single-row deep groove ball bearing is made from robust sheet steel, guaranteeing an exceptionally long service life. The seals made of nitrile butadiene rubber (NBR) reliably protect against dust, moisture and dirt particles while retaining the lubricant securely in the bearing. The CM radial clearance improves load distribution and contributes to smooth running. The bearing is factory-filled with Kyodo Yushi Multemp DRL, a high-performance grease that is over 60 % biodegradable and provides long-lasting lubrication across a wide temperature range (-40 to +150 °C). The low starting torque reduces energy consumption while ensuring consistent performance under varying operating conditions.

Maintenance:
Due to the factory lubrication with Kyodo Yushi Multemp DRL, this bearing is particularly low-maintenance. The highly adhesive lubricant provides long-term protection and minimizes unplanned maintenance stops. Despite the low maintenance requirement, regular monitoring of temperature and vibration is recommended to detect deviations early and further optimize the bearing's service life.

Sealing:
The NBR rubber seals provide reliable protection against solid and liquid contaminants while keeping the lubricant securely in the bearing. This design reduces frictional losses, extends bearing life and minimizes the risk of contamination.
