Products Details

The seat rail is the most important part of the seat assembly, with very high technical content and patent protection. It is not only an important functional part, but also one of the car safety parts. The seat slide rail cooperates with the manual lock device to realize the manual adjustment of the seat in the horizontal position, and with the motor and the driving mechanism, the automatic adjustment of the seat in the horizontal position can be realized, and the market application is very broad. The slide rails are commonly installed under the seat and are used to adjust the front, rear, left and right positions of the seat. The mechanism is generally composed of upper rail, lower rail, locking mechanism (manual), adjustment mechanism (electrical), ball rollers and ball roller cages and other parts.  

Ensure the strength and rigidity of the connection between the seat and the bottom plate, and the seat can maintain the sitting posture when bumping the car, increasing the safety.

Adjust the position of the seat for the driver's convenience, or for a more comfortable space for the passenger.

In the safety performance index of the slide rail: a single slide rail should bear the separation strength of 5900N, the locking strength of 13500N, the peel strength of 18000N, etc.; the sliding rail assembly should bear the static load strength of 1350N•m, 15000 times of alternating Load bearing strength durability and 15,000 times of work durability, etc. In order to ensure that the slide rail should be balanced in all directions, such as positive pressure and side tension, without functional failure, very high requirements are placed on the design of the cross-sectional shape of the slide rail and the raw materials of the slide rail itself, so scientific and reasonable Design the rail section and select high-strength rail material. Usually, the tensile strength of the raw material of the slide rail needs to reach more than 9000MPa.Ningbo Chunji Import & Export Co., Ltd. is located in Dagang Industrial City, Beilun District, Ningbo City, with superior geographical location and convenient transportation.
