buffer gel

Buffer rubber, also known as buffer block, limit rubber, or shock absorber buffer rubber, is a limit buffer rubber component on the chassis, suspension, and shock absorbers of automobiles. It is mainly used to absorb impacts, prevent metal hard impacts, and protect shock absorbers and frames.

main function

When the shock absorber reaches the bottom, it buffers the limit to avoid hard impact

Filter bumps and reduce chassis noise

Protect shock absorbers, suspensions, and frames from being damaged by collisions

Plays as an auxiliary buffer during overloading and pit crossing

Common locations

Upper and lower ends of front and rear shock absorbers

Between steel plate springs

Swing arm and subframe limit position

Rear axle and frame buffer points

Common materials

Natural growth rubber NR

EPDM aging rubber

Polyurethane PU (commonly used for heavy-duty vehicles)

Damage manifestation

There is a "clanging" sound of collision on the rough road

The rubber block cracks, falls off, and is flattened without elasticity

Loose chassis and significantly increased jolting sensation
