FKM TC Oil Seal The TC oil seal consists of a rubber-coated metal cage, a main sealing lip with integrated spring and an additional anti-contamination sealing lip. The function of the rubber seal is to prevent the leakage of the medium along the moving parts. TC oil seal is a kind of seal used by machinery to seal oil. From the sealing function, characteristics, structure type, working state and sealing mechanism of skeleton oil seal, it can be divided into various forms and different names. TC oil seals are generally made of NBR nitrile rubber, FKM fluorine rubber, and HNBR hydrogenated nitrile rubber. Among them, the most commonly used TC oil seals are NBR and FKM.   TC Oil Seal Features 1.NBR TC oil seal is the most commonly used sealing material. It has good heat resistance and good resistance to oils, salt solutions, hydraulic fluids, and gasoline, diesel and other gasoline products. Recommended operating temperature is -40°C to 120°C. It also works fine in dry conditions, but only for intermittent periods. 2. FKM TC Oil Seal is characterized by oil resistance, wear resistance, heat resistance, acid and alkali resistance.

Gyratory Crusher Rockbreaker Applications: Big jobs need big booms and breakers. YZH’s wide range of gyratory booms allow full breaker coverage within the rock box and mouth of the Crusher. YZH’s complete line of large hammers are designed specifically for gyratories to quickly eliminate any bridging or clogging, restoring consistent material flow to the crusher. The gyratory crusher is the mainstay of medium to large duty crushing plants. Typically material is brought to the crusher by large haulage trucks and dumped into a rock box. The gyratory crusher is located at the bottom of the rock box. Material is crushed between the eccentrically mounted rotating crushing cone and the fixed, tapered crushing throat. The Rockbreaker is typically mounted in-line with the upper support of the rotating cone called the spider. This provides superior maneuverability of the Rockbreaker within the gyratory throat. The boom is typically sized to allow full range of motion over the working range of the rock box. The reach should be deep enough to allow the breaker to enter the gyratory for material breaking and concave removal applications.

A rockbreaker boom system is a machine designed to manipulate large rocks, including reducing large rocks into smaller rocks. They are typically used in the mining industry to remove oversize rocks that are too large or too hard to be reduced in size by a crusher. Rockbreakers consist of four major components: hydraulic breaker (used for crushing rocks), boom (arm), hydraulic oil station (power source), and controller (operating system). There are two major types of rock breakers, mobile and stationary - typically placed on a pedestal or slew frame.
