SKF QJ 218 N2MA bearing

Make and Model : The SKF QJ 218 N2MA bearing is a robust and versatile solution, designed primarily for applications requiring reliable management of radial and axial loads. This model is a favorite in the industry due to its ability to operate under heavy load conditions.

Components and Structure:

• Type : Four point contact ball bearing.
• Materials : Made of high quality steel, with a brass cage ensuring superior wear resistance and long-term optimal operation.
• Dimensions : It has a hole diameter of 90mm, an external diameter of 160mm and a width of 30mm. The four-point contact configuration allows it to handle axial loads in both directions.
• Mechanical Characteristics : It is designed for a maximum speed of 7000 rpm and has a radial dynamic load capacity of 186 kN and a radial static load capacity of 200 kN. These values ​​make it a bearing particularly suitable for harsh environments.

Usage Procedure :
SKF QJ 218 N2MA is predominantly used in applications requiring a combination of radial and axial loads, such as industrial machinery, transmission systems and heavy equipment. The bearing must be mounted correctly to avoid warping or premature wear, and the use of hot mounting methods, such as those with induction heaters, is recommended to ensure proper expansion and fixation on the shaft.

Accessories and Combinations :
This bearing can be combined with spacers, dust seals and specific lubricants to extend its life and improve resistance to extreme conditions such as high temperatures and dust contamination.

Formulas for the Calculation of Optimal Parameters:

• Equivalent Load : P = X⋅Fr $+$ $Y\cdot FaP$ = $X$ $\backslash$ cdot $F\_r$ + $Y$ $\backslash$ cdot $F\_a$ $P$ $=$ ​contact angle and FrF_r $F$ r ​and FaF_a $F$ a ​are
• Lifespan : The nominal life in hours of the bearing can be estimated with L10h=(CP)3×60⋅n106L_{10h} = \left( \frac{C}{P} \right)^3 \times \frac{ 60 \cdot n}{10^6} $L$ 10 h ​= $($ P C ​) 3 $\times$ 10 6 60 ⋅ n ​, CC $C$ is the dynamic load capacity, PP $P$ the equivalent load and nn $n$ the speed in rpm

Application Sectors :
SKF QJ 218 N2MA is widely used in sectors such as steelmaking, machine tools, industrial transmissions and pumping systems. Thanks to its robustness and resistance, it is an essential component in environments where operating conditions are extreme.

Maintenance and Evaluation of Used Equipment :
To ensure long life, it is essential to carry out regular cleaning and relubrication. Evaluation of a good used bearing may include analysis of the condition of the contact surfaces, the absence of significant rust or scratches, and smooth movement without abnormal play.

Convenience of Purchasing in Stock :
Purchasing the SKF QJ 218 N2MA bearing ready for delivery in stock can reduce machine downtime and guarantee rapid replacement, which is essential for maintaining high operational efficiency of industrial plants.
