What is SW 135404 seat slider?

The SW seat slider (model 135404) is a core component for seat cushion sliding that is compatible with the Grammer 90.3 airbag seat of Mercedes Benz trucks. It is a key component of the seat adjustment mechanism. It is installed at the bottom of the seat cushion, relying on the built-in ball slide rail to achieve the forward and backward expansion adjustment of the cushion, and is fixed in position with a double tooth locking structure; Made of thickened and rust proof carbon steel through integrated stamping, specially developed for commercial seats in heavy-duty trucks, engineering vehicles, and buses. It is used to replace damaged and stuck sliders in the original vehicle, solve problems such as seat sliding noise, locking failure, and inability to adjust, and balance driving comfort and safety. At the same time, it supports customized processing and is a specialized replacement part for automotive parts maintenance and seat matching.

1. What is the effect of SW 135404 in Mercedes Benz trucks?

SW 135404 is a seat cushion slider specifically designed for the Grammer 90.3 of Mercedes Benz trucks. Its core function is to achieve seamless adjustment of the seat's front and rear, adapt to drivers of different heights to adjust the distance between their legs and pedals, optimize human sitting posture, and reduce back and waist strain during long-distance driving; The thickened steel and double tooth locking structure lock firmly, preventing the seat from slipping and shaking when passing through potholes or sudden braking, ensuring driving safety. The precision ball slide rail slides without any jamming or abnormal noise. The electrophoretic rust proof material can resist oil and water vapor in the cab, and is not easily deformed or rusted under heavy load conditions for a long time. Directly replacing the original parts does not damage the original functions of the seat airbag, lumbar support, etc., greatly reducing the frequency of maintenance and replacement in the fleet, and balancing driving comfort and safety.
