Non standard Ball Bearing

Non-standard Ball bearing mainly bear radial load, but also can bear certain axial load;Non-standard Ball bearing small running resistance, high speed, high rotating precision, low noise and vibration.
Product description

Non-standard Ball Bearing




1.Compact radial structure.

2.More rolling contact surfaces and strong bearing capacity.



Detailed Introduction

Needle roller bearings are equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, L is the roller length), so the radial structure is compact. Its inner diameter and load capacity are the same as other types of bearings. The outer diameter is the smallest, especially suitable for the support structure with limited radial installation size. Needle roller bearings can also be made into thrust needle roller structures, which take up little space in the axial direction, but have extremely low rotational speeds.

Needle roller bearings have high bearing capacity. Depending on the application, bearing without inner ring or needle roller or cage assembly can be selected. At the time, the journal surface and the housing hole matched with the bearing directly serve at the inner and outer rolling surfaces. In order to ensure the same load capacity and running performance as the bearing with ring, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This type of bearing can only bear radial loads.
