Unless otherwise specified, BOX units sizes 25 up to 90 are supplied with long-life lubrication and they don't require any maintenance. BOX11 0, BOX130 and BOX150 are already pre-lubricated as well, with mineral oil VG460.
The use of oil instead of grease offers remarkable improvements under the point of view of the application, especially in the effectiveness and efficiency of the lubrication in the "limit layer" condition as well as under high intermittence applications. Furthermore, synthetic oil lubrication assures a much wider range of low and high operating temperatures. With the use of synthetic oil, the temperature limits turn out to be determined by the properties of the seal material as well as the thermal expansion of the frame material.
 

All units are supplied with plugs for loading, discharging and checking the level of the oil. Furthermore, the units BOX063, BOX075, BOX090, BOX110, BOX130 and BOX150 are accompanied by a breather plug. Before start-up, we suggest to re-place the filler plug in the upper side of the unit with the breather plug. This operation is compulsory on BOX110, 130 and 150.

The combination on the input shaft of 2 taper roller bearings (mounted on size 75 and up to get an high resistance to the axial loads) and 2 nilos (mounted on the unit sizes 75 up to 150 to keep lubricating grease inside the bearings even when they are not touched by the lubrication oil) or, in alternative, special RS shields on such taper bearings, permits the mounting of the whole BOX range, from the size 25 to the size 150, in the positions V5 and V6.

Mounting positions B6 or B7 are also permitted on all the BOX series, thanks to the adoption of 2RS auto-lubricated bearings on the output shaft.
