Description:

991/20030 JCB Seal Kit, for JCB 3CX, 4CX, 214, 215, 217

Material Detail:

Nitrile rubber (NBR)

It has good heat resistance, wear resistance, various lubriC-A-Ting oil, grease, oil and gas mixture, applicable temperature -30~120 degrees Celsius, but can not be used in phosphate ester hydraulic oil and gear oil containing extreme pressure additives, stable performance in gasoline and low aniline point mineral oil.

Polyacrylate rubber (ACM)

Oil resistance, heat resistance, abrasion resistance, ozone resistance, ultraviolet radiation resistance, especially resistance to extreme pressure agent containing lubriC-A-Ting oil, gear oil, motor oil, oil, petroleum hydraulic oil, etc., suitable for -30~150 degrees Celsius work.

Fluorine rubber

Aging resistance, heat resistance, oil resistance, almost all lubriC-A-Ting oil, fuel oil, gasoline, in oil containing extreme pressure additives is not easy to harden, but cold resistance, high temperature wear resistance is poor, permanent compression deformation is large, suitable for temperature -20~250 degrees Celsius.

Silicone rubber

With outstanding high and low temperature resistance, it can be used for a long time at 150 degrees Celsius without performance change;It can be used for 10000h under 200 working conditions, and can maintain its unique flexibility and ozone and weather resistance in the range of -70~260 working temperature.

It has outstanding chemical stability, thermal stability, anti-friction and self-lubricity, and its cracking temperature is above 400.As a result, it can operate normally at a temperature of -200 to 300 degrees Celsius.Except for free fluorine and alkali metals, it has excellent corrosion resistance to chemicals, solvents, hydroxides and acids.

PTFE

PTFE has high flexural strength, even in low temperatures, high electrical resistance and dielectric strength, resistance to water (owing to fluorine's high electronegativity), and low coefficient of friction. PTFE's density is also very high, at 2200 kg/m3.

FKM

FKM is a fully synthetic polymeric elastomer material. Compared with other rubber materials, fluorinated rubber has high tensile strength and structural strength in physical properties, high temperature resistance, and static sealing can be used in an environment of 200 degrees Celsius.

PU (Polyurethane)

Polyurethane is an ideal material for vibration control appliC-A-Tions because it can be very resilient, minimize noise and withstand a wide range of loads. The impact resistance of polyurethane is exceptional, even at low temperatures, and it also offers resistance to cracking, tearing, breaking or swelling.
