What is the difference between N and NU bearing?
NU style bearings have two machined flanges on the outer ring and no flanges on the inner ring. The rollers and cages are assembled in the outer ring. … N style bearings have two machined flanges on the inner ring and no flanges on the outer ring, with rollers and cage on the inner ring.
What is NU type cylindrical roller bearing?
NU Type: As seen in the photo, this type of cylindrical roller bearing does not posses any collar on its inner race, the rolling elements are mounted in the flanged Outer race. This type of bearing has the capability to carry only radial loads and cannot carry any axial load on it.
What is a QJ bearing?
Four-point contact ball bearings (QJ bearings) are a specific type of angular contact ball bearings. In many applications one QJ bearing is an interesting alternative to a matched set of single-row angular contact ball bearings.
What does LB mean on bearing?
Applicable options
| Suffixes – Cage design | |
|---|---|
| LA | Machined light alloy cage, outer ring centred |
| LB | Machined light alloy cage, inner ring centred |
| LL | Machined light alloy cage, window-type, inner or outer ring centred (depending on bearing design) |
| M | Machined brass cage, roller centred |
What is NF bearing?
NF (RIF, RF) Cylindrical bearing type NF has single-ribbed outer and double-ribbed inner rings and can support heavy radial loads, as well as light unidirectional thrust loads up to 10 percent of the radial load.
How do spherical roller bearings work?
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.
