About Machining Belt Pulley

Machining Belt Pulley belongs to hub parts, is generally relatively large in size, and its manufacturing technology is mainly casting and forging. Generally, the larger size is designed by casting method. The material is usually cast iron (with good casting performance), but rarely cast steel (with poor casting performance); generally, the smaller size can be [...]

Spherical Ball Bearing Seat

Spherical ball bearing seat is a bearing unit which combines rolling bearing with bearing seat. Most of the outer spherical bearings are spherical in outer diameter, which are mounted together with the bearing seat with spherical inner hole. They have various structures, good versatility and interchangeability. At the same time, this kind of bearing also [...]

Role of Block Bearings

Brief Introduction for Block Bearings: Bearing with seat is composed of outer spherical ball bearing with seal on both sides and cast (or stamped) bearing seat. The inner structure of the block bearings is the same as that of the deep groove ball bearing, but the inner ring of the bearing is wider than the [...]

About Bearing Pedestals

What are the functions of bearings and bearing pedestals? Bearing is used to make the shaft run along the circumference and support the shaft, the conventional use is two bearings or more, its role is to make the shaft run normally, and the bearing seat is used to support the bearing, fixed the outer ring [...]

About Dump Pumps

The working principle of the dump pumps is the same as that of the external mixing self-suction pump. The difference is that the backwater does not flow to the outer edge of the impeller, but to the inlet of the impeller. When starting an internal mixing self-priming pump, the back-flow valve at the front and [...]

Hydraulic Cylinder can’t Drive Load when Working

Why does Hydraulic cylinder can not drive load when working? The main manifestations are inaccurate stopping of piston rod, insufficient thrust, reduced speed and unstable operation. The reasons are as follows: (1) Internal leakage of hydraulic cylinder. Internal leakage of hydraulic cylinder includes leakage caused by excessive wear and tear of cylinder block seal, piston [...]

Introduction of Hydraulic Cylinder

Introduction of Hydraulic Cylinder: Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or oscillating motion). It is simple in structure and reliable in operation. When it is used to realize the reciprocating motion, the speed reducing device can be eliminated, and there is no transmission [...]

Hydraulic Cylinder Can’t Reach the Stroke

Why does the hydraulic cylinder suddenly fails to reach the stroke? Hydraulic Cylinder Stroke is very important , This may be due to the following reasons: 1. Blockage caused by foreign bodies entering the hydraulic cylinders, or damage of the cylinder block, and inadequate movement. 2. Blockage in the mechanical part of the hydraulic cylinders [...]

About Hydraulic Cylinders

Hydraulic cylinders  are hydraulic actuators which converts hydraulic energy into mechanical energy and makes linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, it can avoid deceleration device, and has no transmission clearance, so it is widely used in various mechanical hydraulic systems. [...]

Difference between Hydraulic Cylinder and Air Cylinder

There are three kinds of differences between Hydraulic Cylinder and Air Cylinder: 1. Different in nature Hydraulic Cylinder: Cylinder generally refers to hydraulic cylinder (mechanical equipment). Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and makes linear reciprocating motion (or swing motion). Air Cylinder: Cylindrical metal parts that guide the [...]
