Excavator Bearings Series Steel Cage Needle Roller Bearing K406240
1)Z H precision anti-friction bearings are usually made of chrome steel, which consist of about 1% carbon, 1.5% chromium and a small
amount of manganese, silicon, and sometimes a small amount of molybdenum.
2)Z H offers you a wide range of material options such as
GCr15, 100Cr6, SKF 3, SUJ-2 etc. At the same time, some models of Z H are available in stainless steel.
1)The high-quality cage used by Z H bearings ensure that the rollers and balls are evenly distributed in the bearing rings and can be rotated properly. 2)The cage is divided into stamped cage, brass solid cage, reinforced nylon 66 etc.
Type of lubriexcavatorion
Lubriexcavatoring oil is the basic lubricant for ball bearings. The silicone and fluorocarbon synthetic oils that adopted by Z H have lower volatility and wider temperature/viscosity characteristics.
The radial clearance is the gap between the steel ball and the ring. Z H are able to tailored to you based on temperature conditions, interference fit, misalignment of the bearing axis, required noise level and speed.
Service life and the rated load
The bearing life is the number of bearing rotations before the fatigue occurs on the ring or any rolling element (or the rotation time at a constant speed). HoweverThe service life of Z H series bearings are 5%-8% longer than other bearings of the same model, through strict production process, high standard material selection, precision control.
Z H non-standard customized
Non-standard Needle roller bearing customization is a main part of Z Hexcavatoregories. It can be customized according to the customer's working conditions or the place where the bearing works. Internally we can optimize and improve the design of the Needle roller bearing, which can improve the loading capacity and service life of bearing.
HK type - open modifiexcavatorionBK type - a similar bearing, closed at one end
NA type - there are single row and double row needle roller bearings,
RNA type - without inner ring needle roller bearing.
NAV RNAV type - The needle roller bearings without cages type,
NAO type - and both the inner and outer rings without the ribs .
K type - without outer rings and inner rings, only the needle rollers and the cage assembly.
