NSK Bearing NUP205ET7

Product description of NSK Bearing NUP205ET7

NSK Bearing NUP205ET7 Single row cylindrical roller bearings with cage are suitable where:Bearing arrangements are subjected to very high radial loads

Not only high radial forces but also axial loads from one or both directions must be supported by the bearing position (semi-locating or locating bearing function)

Bearing arrangements must have very high rigidity

Axial displacements of the shaft relative to the housing must be compensated without constraint in the bearing (in the case of bearings with a non-locating or semi-locating bearing function)

High radial loads and very high speeds occur but the very high radial load carrying capacity of full complement cylindrical roller bearings is not required

The bearings should be separable (one bearing ring can be removed for easier mounting).

NSK Bearing NUP205ET7 Full-complement Cylindrical Roller Bearings Cage-less, full-complement cylindrical roller bearings have the maximum possible number of rollers and can sustain much heavier loads than cylindrical roller bearings of the same size with cages. On the other hand, high-speed capability is inferior to the bearings with cages.

NSK Bearing NUP205ET7 The open-type single- and double-row bearings are mostly used in general industrial applications at low speed and under heavy load, and the shielded-type double-row bearings are often used in crane sheaves. Cylindrical Roller Bearings for Sheaves Improved seal: Contact seal increases resistance to entry of water or foreign substances. High load capacity: When used as a sheave bearing, radial and axial load capacities are increased Corrosion resistance: Phosphate surface treatment improves resistance to rust. Easy to apply grease: Holes provided on inner ring facilitate grease replenishment, even while the bearing is mounted. Fewer surrounding parts: With snap rings for the outer ring, fewer parts are required around the bearing for a more cost-effective sheave. Free Space of Cylindrical Roller Bearings Cylindrical roller bearings often employ grease lubrication because it makes maintenance easier and simplifies the peripheral construction of the housing.Select a grease brand appropriate for the operating conditions while noting the grease fill amount and position of the bearing and housing.

Cylindrical roller bearings can be divided into types NU, NJ, N, NF, NH, and NUP according to the collar, collar ring, and position of the inner or outer ring ribs. Even if bearings belong to the same Dimension Series, they may have different amounts-of free space depending on whether the cage. provided is made from pressed-steel or from machined high-tension brass. When determining the grease fill amount, please refer to Tables 1 and 2for the free space 0f ÑÙ type bearings.

For other types, the free space can be determined from a free space ratio based on the NU type, as known in Table 3. For example, the free space of anNJ310 bearing with a pressed steel cage may be calculated approximately as 47 cm?. This result was obtained by multiplying the free space of the bearing(52 cm)_ in Tablé 1 by the space ratio 0.90 for the NJ type (Table 3).
