Agricultural Bearing is a special bearing

Agricultural Bearing is a special bearing, because its structure is very special, bore cylindrical, square, hexagonal; the outer diameter of cylindrical, spherical, cylindrical mixing spherical shape. Some bearings also with square or round holes punching bearing, this bearing can simplify the main body, but also easy bearing installation and removal. Agricultural Bearings ring structure is very special, is a rubber lip curling sheet steel skeleton three large amount of interference contact seals. It can block the external bearing soil, the water enters the sand, but also to prevent the loss, sealing performance inside the bearing grease well.

A special bearing-Agricultural Bearings

We are a professional bearing manufacturer in the world. Established in 2000, has been specializing in bearings' design, production, sales, marketing and service. For 13 years experiences, our bearings have flied to USA, Europe, Middle East, Asia and Africa.Today introduced a special bearing-Agricultural Bearing is widely used in special sealed bearing on the domestic and foreign agricultural machinery. It is based disc plow, disc harrows and other farming machinery transfer load, farming in muddy water easily enters the bearing, the working shaft Equidistant installation (harrow plow shaft or axis) on multiple sets of bearings and other characteristics, designed a good sealing performance, good aligning performance, large carrying capacity, easy installation and removal of the bearings.

agricultural bearings

The bearings are machinery and equipment integral to key components, and precision spindle bearings precision more direct impact on the level of precision machinery and equipment, the type of bearing load should be considered approximate size, orientation, whether there is impact, high and low speed, aligning requirements , allow space and other factors many categories of agricultural machinery, the general situation is poor working conditions, especially in the field to do business like bad, so select the type of bearing heavy important, it directly affects the reliability of the work machine. Accuracy, we do not need as demanding as precision machinery, which is the nature of the job determines the agricultural bearings.

Crane bearing applications

Crane is in a certain range of vertical lifting and carrying heavy loads of multi-level action lifting machinery. Also known as crane. Belongs to the material handling machinery, but also for marine crane bearing, working characteristics of the crane is to do a batch Appropriate institutional movement, that in a work cycle Reclaimer, transport, unloading and other movements are alternately work Development and use of cranes on the market more widely. Crane hoisting mechanism includes running mechanism, luffing mechanism, slewing mechanism and metal structure. Hoisting mechanism is the basic working mechanism of the crane, mostly by hanging systems and winches composition, but also lift weights by the hydraulic system. Operational mechanism for horizontal transport of heavy or longitudinal adjustment of the position of the crane work, usually consists of motor, reducer, brake and wheel components. Luffing mechanism is equipped with only the jib crane, when the jib looked amplitude decreases, the amplitude increases when bent, sub balanced and unbalanced luffing luffing two. Boom slewing mechanism for causing rotation is determined by the drive means and the rotary bearing device component. Metal structure is the skeleton of a crane, the main carrier such as bridge, jib and mast can be a box-shaped structure or truss structure,But also for the web structure, and some can be used as a steel support beam.

Single row crossed roller slewing bearing material

Under normal circumstances, angular contact bearing slewing ring rolling with the overall hardening of high carbon chromium bearing steel. Slewing ring is hardened steel, when the user does not have special requirements, generally used in 50MN steel, but sometimes in order to meet the needs of specific applications, and in the host, the surface can also be in accordance with other brands under certain conditions,Excavator Slewing Bearing the use of use to provide hardened steel. Wheel bearing retainer having a monolithic, segmentation, isolated blocks and other structures. Where the overall style and segmented cage with 20 ZL102 cast steel or aluminum. Isolation block polyamide resin 1010, ZL102 aluminum casting and other manufacturing. In recent years, with the development of a continuous industrial materials are segmented cage design applications.

Slewing ring in the real industrial applications is very broad

Slewing ring in the real industrial applications is very broad, known as: "the machine joints", its main application is widely used: Truck cranes, railway cranes, port cranes, angular contact bearing marine cranes, metallurgical cranes, container cranes, excavators , filling machines, as well as CT machine standing wave treatment, navigation instruments, radar antenna base, missile launchers, tanks, robots and a revolving restaurant, and so on.Slewing widely used construction machinery is slewing initial applications are most widely used in places such as earthmoving machinery, excavators, disintegration machine, stacker reclaimer, graders, rollers excavator slewing bearing , compaction machines, drilling machines, boring machines.thin section bearing Others include:Concrete: Concrete pump truck, concrete mixing machine boom, belt fabric machineFeeding machines: disc feeder, 

Calculation and analysis of high-speed precision spindle bearing thermal properties

Bearing frictional torque, the higher the speed, the frictional heat generated by the more, the higher the temperature rise of the bearing, the bearing for the high speed bearing (dn values in the range of 2,000,000) the use of oil-air lubrication can be well suppressed bearings the temperature rise. For the friction torque and friction heat precision spindle bearings, the greater torque, bearing fever mainly related with the friction torque. Frictional heat generated by the more. According to the formula derived Palmgren, the bearing friction torque has two parts: frictional torque occurring lubricant viscosity and friction torque and speed independent of load occurs.
