The Basic Information of pneumatic cylinder and air cylinder fisheye joint

The rod-end joint bearing is a kind of joint bearing with rod end or mounted on rod end, which belongs to a class of joint bearings. In the narrow sense, the rod-end joint bearing should refer to the common fisheye joint.

There are three structures of the pneumatic cylinder:

1. Cylinder: The inner diameter represents the output force of the cylinder. The piston should slide smoothly back and forth in the cylinder, and the surface roughness of the inner surface of the cylinder should reach Ra0.8μm.

2. End cover: The end cover is equipped with intake and exhaust ports, sealing ring and dust ring to prevent air leakage and dust from mixing into the cylinder. There is also a guide sleeve to improve the guide accuracy of the cylinder, bear a small amount of lateral load on the piston rod, reduce the amount of bending when the piston rod extends, and extend the service life of the cylinder.

3. Piston: The pressure parts in the cylinder are equipped with piston seals to prevent the air from each other in the left and right chambers of the piston. The wear-resistant ring on the piston can improve the guidance of the cylinder, reduce the wear of the piston seal ring, and reduce the friction resistance.

4. Piston rod: an important force part in the cylinder. Usually use high-carbon steel, the surface is treated with hard chromium plating, or stainless steel is used to prevent corrosion and improve the wear resistance of the sealing ring.

Fisheye joint is a self-lubricating rod-end joint bearing, which belongs to a kind of joint bearing. The function is to connect the rods intersecting two centerlines, in which the axis installed in the “fish eye” can rotate around the centerline at an angle.

Fisheye joint belongs to one kind of joint bearing. Its function is to connect the rods intersecting two centerlines. The axis installed in the “fisheye” can rotate around the center line at a certain angle. Its sliding contact surface is an inner sphere and an outer sphere, which can rotate and swing at any angle when moving. It is made by surface phosphating, blasting, inserting pad, spraying and other special processing methods. Joint bearing has great load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication and so on. Characteristic.
