What is a CRB bearing?
Ideal for high speeds, high temperatures and high load capacity (primarily radial), C&U cylindrical roller bearings are engineered to minimize friction and increase performance and life. CRB are available in a wide range of bearing tolerances, and are available in single or double row.
What is HK bearing?
HK Series – Drawn cup needle roller bearings. Needle roller bearings use small, cylindrical rollers which are long and narrow. These bearings allow for a large surface area to be in contact with the outer race and are much more compact than cylindrical rollers.
What is spindle bearing?
Spindle bearings are single-row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed designs. Spindle bearings have restricted tolerances.
Which bearing is used for high load?
Thrust Ball Bearings A thrust bearing permit rotation between parts, but they are designed to support a high axial load while doing this (parallel to the shaft). Higher speed applications require oil lubrication.
What is NJ bearing?
NJ style bearings have two machined flanges on the outer ring and a machined flange on one side of the inner ring. The roller and cage assembly is in the outer ring. The integral flange on the inner ring allows this bearing to carry an axial load.
What is a flange bearing?
What is a flange bearing? Flange bearings consist of a cylindrical body with a flange at one end. These bearings are capable of supporting radial loads as well as light axial loads due to the flange providing a thrust surface.
How do spindle bearings work?
Bearings are typically composed of a ring or series of rings with a ball or other rolling element that streamlines the motion of the spindle in the desired direction. Depending on the equipment and desired motion, bearings can be engineered to facilitate the movement of spindles on both lateral and radial axes.
Why ball bearings Cannot take heavy load?
Because the contact area between the balls and races is so small, ball bearings can’t supoert as much load as other bearing types, so are best suited for light to moderate loads. However, their small surface contact also limits the heat generated by friction, which makes ball bearings useful in high-speed applications.
