Specifications of INA Bearing SL045028-D-PP-2NR

INA Cylindrical Roller Bearing SL045028-D-PP-2NR is a two-row, locating bearing, central rib on outer ring, 3 ribs on inner ring, full complement roller set.

Size: 140 mm x 210 mm x 95 mm

Material: Bearing Steel Structure: Cylindrical roller bearing, two-row Usage: It is used in applications where high radial loads and low to moderate axial loads are present.

Advantages:

  1. It can accommodate heavy radial loads, as well as light thrust loads. 2. The locating feature on the inner ring helps to reduce axial movement or skewing of the inner ring, which can reduce wear and extend bearing life.
  2. The full complement of rollers reduces the chances of frictional contact between the rollers and the bearing rings, which can result in less friction, heat and noise.

Disadvantages:

  1. It is more expensive than other types of roller bearings.
  2. The outer ring may be susceptible to wear and tear due to the high load capacity.

Product description of INA Bearing SL045028-D-PP-2NR

INA Bearing SL045028-D-PP-2NR, it belongs to INA Bearing > Roller Bearings > Cylindrical Roller Bearings,

Classic cylindrical roller bearings have an extremely high radial load carrying capacity and high rigidity. In addition to high radial loads, cylindrical roller bearings can also support axial loads if they are used as semi-locating or locating bearings. Whereas radial loads are transferred via the raceways, axial loads are transferred via the rolling element end faces and ribs, which, of course,limits the axial load. And this is precisely where Schaeffler gets to work!

We developed the TB roller to significantly increase the bearing operating life under axial load. The special torus-shaped curvature of the end faces of this roller enables loads to be distributed across a significantly greater surface area.Due to this reduced surface pressure, semi-locating and locating bearings provide a number of benefits:

The permissible axial load is increased by a factor of 1.5 compared with standard bearings (now Fa/F, s 0.6 compared with Fa/F, s 0.4 previously)· Lower bearing temperatures, since the frictional torque under axial loadisreducedbyupto50% Significantly less wear on the rollers under axial load due to improved lubricant film formation

INA Bearing SL045028-D-PP-2NR Bearings have a longer operating life under axial load The TB design increases the efficiency of non-locating bearings by improving the lubrication in the contact between the rollers and the ribs. INA cylindrical roller bearings with optimized rib contact

Our full-complement INA cylindrical roller bearings are true star performers when it comes to load carrying capacity and rigidity.What most people don`t know is that they support unusually high axial loads - up to 60 percent of the radial load in fact. These bearings have a significantly longer life under axial loads and also have reduced friction thanks to the improved contact between the rollers and the ribs. This is certainly an interesting combination when considering downsizing and increasing energy efficiency.

INA Bearing SL045028-D-PP-2NR In bearings of this type, the cylindrical rollers are in linear contact with the raceways. They have a high radial load capacity and are suitable for high speeds.

There are different types designated as NU, NJ, NUP, N, NF (for single-row bearings), NNU, and NN (for double-row bearings depending on the design or absence of side ribs).The outer and inner rings of all types are separable.Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
