Cooperation of NSK Bearings I. Collaborative selection of the inner diameter and outer diameter dimensions of the rolling NSK bearing is made according to the standard; NSK bearing inner ring and shaft; the cooperation between the outer ring and the seat hole can only be controlled by the journal. The civil service and the seat hole are officially completed. The cooperation between the inner ring and the shaft of the NSK bearing is selected from the base hole; the cooperation between the outer ring and the seat hole of the NSK bearing is made by the base shaft system.
Correct selection of cooperation; it is necessary to know the practical load conditions of NSK bearings; working temperature and other needs; and in practice it is very difficult. Therefore, most of the conditions are based on the use of fine research to select cooperation.
Second, the weight of the load ferrule and the shaft or the shell between the over-win depends on the load.

First, adhere to the NSK bearing and its surrounding environment. Even if very small dust enters the NSK bearing; it will increase the wear of the NSK bearing; oscillation and noise.
Second, the device should be careful and careful; strong stamping is not allowed; NSK bearings cannot be directly hit; the pressure is not allowed to pass through the rolling body.
Third, the use of the right device; try to use special things; try to avoid the use of cloth and short fibers and the like.
Fourth, to avoid the corrosion and rust of NSK bearings; the best not to take NSK bearings directly by hand; to apply high-quality mineral oil before operation; especially in the dry season and summer to pay attention to rust.

H135 A type CPE performance
Mainly used as the impact resistant modifier of PVC. At present, it takes 95% share of the impact resistant modifier market of domestic PVC. The additive shares of H135 A type CPE as the impact resistant modifier of PVC profile shapes is 9~ 12; the shares as the impact resistant modifier of PVC water feeding pipe and other liquid transfer pipe under pressure is 4~ 6; this can effectively improve the low temperature resistant impact property of PVC product. In addition, H135A type CPE is widely added into the products including PVC plate, sheet, calcium-plastic box, case of household appliances and electrical appliance fittings to improve the mechanical property and electrical property.
H135 A type CPE can be compatible and use with most plastics and rubbers simultaneously. The polymer cross blend system with bad compatibility can take CPE as bulk filler. The rubbers used together with CPE include caoutchouc, butadiene styrene rubber, ethylene propylene diene copolymer, polyurethane rubber, acrylonitrile butadiene rubber, neoprene and chlorosulfonated polyethylene etc. The plastics used together with CPE include PVC, PE, PP, EVA and PA etc, which greatly improve the low temperature resistant impact property and increase flame resistance, oil and aging resistance, corrosion resistance and insulatibity. This can make the plastic product have high filling property and reduce production cost.

Packing and Storage :

PP bags with PE film inside, Net Weight of 25 Â± 0.2kg per bag ; as the viscoelastic and water absorption of CPE resin are strong, this product shall be stored in the dry and ventilated warehouse with stack height no more than 10 bags and avoid solarization, damp and takes strict precautions again stress. It is not dangerous cargo.
