This C-Lube Machined Type Needle Roller Bearings are may lead to a short bearing life.manufactured based on JIS (See page A31.). The tolerances for the smallest single roller set bore diam-eter of bearings without inner ring are based on Table 14 on page A33. ■Fit■Precaution for Use1 Do not wash C-Lube Machined Type Needle Roller Bearing with organic solvent and/or white kerosene, which have the ability of removing fat nor leave them in contact with the above agents.The recommended fits for C-Lube Machined Type 2 To ensure normal rotation of the C-Lube Machined Needle Roller Bearings are shown in Tables 21 to 23 Type Needle Roller Bearing, apply a load of 1% or on pages A41 and A42.■Allowable Rotational SpeedThe allowable rotational speed of C-Lube Machined Type Needle Roller Bearing is affected by mounting and operating conditions. The reference dmn value (1) is 20,000.Note(1)dmn value = (Bore diameter of bearing [mm] + Outside rotational [mm])/2} x diameter of bearing speed [min-1]■LubricationAs the internal space of C-Lube Machined Type Needle Roller Bearing is filled with thermosetting solid-type lubricant C-Lube, regreasing is not possible due to the structure.over of the dynamic load rating at use.3 The operating temperature range is -15〜+80˚C. For continuous operation, the recommended oper-ating temperature is +60˚C or less.4 When using two or more C-Lube Machined Type Needle Roller Bearings adjacent to each other on the same shaft, it is necessary to obtain an even load distribution. On request, a set of bearings is available, in which bearings are matched to obtain an even load distribution.Further, C-Lube Machined Type Needle Roller Bearing for food machinery is also available.
