INA's SX crossed rolelr bearing

        Since each Cross-Roller Ring unit contains high-quality Germanic grease imported, you can start using the product without replenishing grease.  However, the product requires regular lubrication since it has a smaller internal space than ordinary roller bearings and because the rollers need frequent lubrication due to their rolling contact structure. To replenish grease, it is necessary to secure greasing holes that lead to the oil grooves formed on the inner and outer rings.  As for the lubrication interval, normally replenish grease of the same group so that it is distributed throughout the interior of the bearing at least every six to twelve months.  When the bearing is filled up with grease, the initial rotation torque temporarily increases.  However, surplus grease will run off of the seals and the torque will return to the normal level in a short period.  The thin type does not have an oil groove.  Secure an oil groove inside the housing for lubrication
