Tools To mount or dismount Y-bearing units, the following tools are required: The description of stainless steel high chromium content steel was wrong. The permissible speed for grease lubricated bearings with a ring centred cage should be lower. To attach Y-bearing units to the support surface, SKF recommends using 8. HME and HM lock nuts are not listed with the correct spanner.

Eles devem ser trocados de lugar. The dimension B is listed in the table, but not shown in the sketch. Rolamentos Y e unidades de rolamento Y The basic load industrisis and the fatigue load limit for bearing NJ are too high.

Attaching Y-bearing units to the support base To reduce vibration and enable heat to dissipate from the unit, the housing must be firmly attached to the support base. Hook spanners are part of the comprehensive SKF assortment of high quality mounting and maintenance products.

Table 1 Permissible angular misalignment for rotating shafts In print: The basic load ratings, sif fatigue load limit and the speed ratings for bearing BECBM are too low. When designing bearing arrangements with rotating housing washer in combination with misalignment or when the shaft wobbles in relation to the housing, contact the SKF application engineering service.

To reduce vibration and enable heat to dissipate from the unit, the housing must be firmly attached to the support base.

Proper mounting requires experience, accuracy, a clean work environment and the appropriate methods and tools. Wrong exponent in formula for permissible axial load in circulating oil applications F ap oil. NUH bearings have an outer diameter of mm.

Some formulas are wrong because indices are mixed up. Failure to carefully follow applicable mounting instructions can result in premature bearing failure or improper performance. Bearing frictional moment is not asymptotically limited to 2,0 Correction: Small axial clearance enables simple and cost-effective bearing arrangements e.

The unit for the taper is the slope, not degree. For detailed information, contact the SKF application engineering service. For these applications, bearings with a modified shaft washer designation suffix VU should be used.

In the designation system, add VU under Group 4. Brazil Produtos Catalovo, unidades e mancais Unidades de rolamento Unidades de rolamento Y unidades de rolamento de esferas Ball bearing plummer block units Mounting and dismounting.

Mounting and dismounting

The method used for mounting a Y-bearing unit depends on: Add the lock nut width B to the illustration. Three symbols for the grease characteristics are incorrect. Under Axial clearance, bearings with designation suffix VU should be mentioned. Current online version Deep groove ball bearings – Section 1 Page Explanation: The last sentence under Misalignment could be more clear. Leave the Y-bearings, housings for Y-bearings or Y-bearing units in their original packages until immediately prior to mounting so that they are not exposed to any contaminants.

Bearing frictional moment is not asymptotically limited to 2,0. Y-bearings and Y-bearing units are reliable machine elements that can provide long service life, provided they are mounted and maintained properly. The internal clearance reduction should be calculated using the bearing mean diameter. Eu gostaria de saber Mounting and dismounting Y-bearings and Y-bearing units are reliable machine elements that can provide long service life, provided they are mounted and maintained properly.

Replaced the graph with corrected version. Eu gostaria de saber For additional information about mounting and dismounting Y-bearings and assembling Y-bearing units, refer to the SKF bearing maintenance handbook. Pesquisa e desenvolvimento Portal do Fornecedor. Pesquisa e desenvolvimento Portal do Fornecedor. Correction shown in red: The tightening angles, listed for bearings on an adapter sleeve, are to be used as guideline values only, as it is difficult to establish an exact starting position.

The title for table 1 needs an extension. B is the lock nut width without the locking device. For information about SKF maintenance products, refer to Maintenance products.
