The company currently has more than 1,500 types of skeleton oil seal molds, which are widely used in aviation, automobiles, motorcycles, railways, vehicles, ships, home appliances, engineering machinery and other industries. Suitable for sealing of rotary motion and reciprocating motion. Installed on various heavy-duty engines, gearboxes, axles, ships, cylinders, etc. It mainly prevents the sealed medium (gas, liquid) from penetrating and external foreign matter from entering the body.

Product parameters

How to identify the oil seal: Manufacturer LOGO - oil seal type - inner diameter - outer diameter - height - material such as: CXIK TC 40*62*12 - NBR means: CXIK brand double-lip inner skeleton oil seal, inner diameter 40, outer diameter 62, thickness 12, The material is nitrile rubber oil seal.

Material hardness: 70(SHA), 75(SHA), 80(SHA), 85(SHA).

Product media: gasoline, diesel, hydraulic oil, water, emulsion, etc.

Oil seal types: Skeleton oil seals include TC, TG, VC, VG, SC, SG, TB, VB and other types.

C-type skeleton oil seals are internal skeleton oil seals and can be divided into five types: SC type, TC type, VC type, KC type, and DC type, which are single-lip internal skeleton oil seals, double-lip internal skeleton oil seals, and single-lip springless internal skeleton oil seals. , double lip springless inner skeleton oil seal, double lip double spring inner skeleton oil seal. The G-type skeleton oil seal has a thread shape on the outer circle. Its type is the same as the C-type, but it is modified to have a thread shape on the outside in terms of technology. It is similar to the function of an O-ring, that is, it plays a role in strengthening the sealing effect and also plays a role in Make sure the oil seal is not loose.

Type B skeleton oil seals have rubber inside the skeleton or no rubber inside and outside the skeleton. Without rubber, the heat dissipation performance will be better.

Type A skeleton oil seal is an assembled oil seal. Its structure is relatively complex compared to the above three types. It is characterized by better and excellent pressure-bearing performance.

Oil seal material: (NBR/FKM/ACM/HNBR/SI)+skeleton+spring.

Nitrile rubber (NBR): wear-resistant, oil-resistant (cannot be used in polar media) temperature resistance: -40~120℃.

Hydrogenated nitrile rubber (HNBR): wear resistance, oil resistance, aging resistance, temperature resistance: -40~200℃ (stronger temperature resistance than NBR).

Fluorine rubber (FKM): acid and alkali resistant, oil resistant (resistant to all oils), temperature resistant: -20~300℃ (oil resistant is better than the previous two).

Polyurethane rubber (TPU): wear resistance, aging resistance, temperature resistance: -20~250℃ (excellent aging resistance).

Silicone rubber (PMQ): heat-resistant, cold-resistant, small compression permanent deformation, low mechanical strength, temperature resistance: -60~250℃ (excellent temperature resistance).

Polytetrafluoroethylene (PTFE): good chemical stability, resistant to acids, alkalis, oils and other media, wear-resistant and high-temperature resistant, high mechanical strength and good self-lubricating properties.

Generally speaking, the commonly used materials for skeleton oil seals are nitrile rubber, fluororubber, silicone rubber, etc.

Material hardness: 70(SHA), 75(SHA), 80(SHA), 85(SHA).

Product media: gasoline, diesel, hydraulic oil, water, emulsion, etc.
