Steel sleeve ------ high quality/high precision/long life

Quanzhou Terris Machinery Manufacturing Co., Ltd. is a manufacturer specializing in the production of chassis parts for various construction machinery such as excavators and bulldozers. We produce more than a thousand types of engineering machinery bushing series with an inner diameter of φ30-180 . The material is carbon alloy and carburized. The hardness is HRC56-62. We can produce products according to the drawings and processing requirements of customers.

The bushings produced by our company have certain advantages, especially in situations where there is high impact and a lot of dust, but effective sealing cannot be achieved. At the same time, various types of oil holes and oil grooves are designed, which can not only meet the needs of oil passage, And it can effectively bury the dust, thereby increasing the service life of the bearing. Through different heat treatment methods, it can meet both wear resistance and high impact requirements.
Shaft sleeve: The shaft sleeve is generally used in conjunction with the bucket shaft. Plays the role of fixed and sliding bearings. The diameter is generally: 30-180mm. Its operation is smooth, reliable and noiseless. Under liquid lubrication conditions, the bushing surface is separated by lubricating oil without direct contact, which can also greatly reduce friction loss and surface wear.

1 ) Internal texture type: straight groove, eight-shaped groove, hole-shaped groove, spiral groove, composite groove, etc.

2 ) Heat treatment

A ) The hardness is HRC45-48, generally used for processing medium carbon steel and medium carbon alloys.

B ) After surface carburization, the hardness is HRC56-62. It is generally used for the treatment of low carbon steel and low carbon alloy steel.

Our company can specially customize according to user requirements and specific models.
