1 bumper piston

Batch of shock absorber pistons for doors on kitchen, wardrobe, home and bathroom furniture. Provides soft and cushioned closing of the hinged door , avoiding slams. It is screwed on the surface of the furniture.

HOW TO CALCULATE THE MOUNTING:
Add E+1 to calculate A and X, being E the thickness of the board.
• For wooden and aluminium doors.
• For overhangs other than 15 mm, calculate value A+15-overhang.
• For doors wider than 450 mm the use of 2 springs is recommended.

CALCULATING STRENGTH OF STAY:
F: Force supported by piston in kg.
P: Weight of door in kg.
H: Height of door in mm.
B: Fixing point of piston in mm.
F = (P x H x 0,6) / B

CALCULATING WEIGHT OF DOOR:
P = Weight of the door in kg.
H = Height of the door in cm.
A = Width of the door in cm.
e = Thickness of the door in cm.
d = Density of door material.
Particle board: d = 0,72 kg/dm3.
MDF: d = 0,75 kg/dm3.
Glass: d = 2,54 kg/dm3.
P = (H x A x E x D) / 1000
