Volvo loader L90 and L120 gasket

The hydraulic cylinder gasket in Volvo L90 and Volvo L120 is installed at the rod gland area of the cylinder head. It remains in direct contact with the chrome plated piston rod. The primary function is to prevent dust, mud, sand, and abrasive particles from entering the hydraulic cylinder. The inner diameter typically ranges from 70 mm to 120 mm depending on lift or tilt cylinder size. Cross section width is generally between 10 mm and 20 mm. Groove tolerance is commonly manufactured to H9 class for proper press fit. Maximum rod linear speed can reach 0.5 m per second. The wiping lip is designed with single or double lip geometry at approximately 15 degree contact angle for effective contaminant removal.

The Volvo loader cylinder wiper seal gasket is commonly manufactured from polyurethane PU with hardness between 90 and 95 Shore A. In specific applications, reinforced NBR compounds may also be used. Standard polyurethane operates within a temperature range of minus 30 to plus 100 degrees Celsius. PU provides significantly higher abrasion resistance compared to conventional rubber materials. Although the wiper seal is not pressure bearing, it must withstand oil splash exposure up to 5 bar. The piston rod surface roughness should be below Ra 0.4 microns to minimize wear. Prop
