The outer diameter (OD) of the cam follower (stud or yoke) can be the standard cylindrical shape or be crowned. Crowned cam followers are used to keep the load evenly distributed if it deflects or if there is any misalignment between the follower and the followed surface. They are also used in turntable type applications to reduce skidding. Crowned followers can compensate for up to 0.5° of misalignment, while a cylindrical OD can only tolerate 0.06°. The only disadvantage is that they cannot bear as much load because of higher stresses.

Agricultural bearings are used in conveyors, lawn mowers, combines, hay balers, planters/grain drills, augers, cotton strippers, and more.  They are designed to stand up to extreme conditions and loads.  There are many different designs available.  Their basic components are inner and outer rings, balls, and retainers.  The inner race can be round, square, or hex, and the outer race can be either cylindrical or spherical.  Most agricultural bearings are sealed on both sides with single, double, or triple lip.New domestic modelsOld domestic modelInner diameter (mm)Outer

Because the rolling body in the thrust tapered roller bearing is a tapered roller, the rolling surface can form a pure rolling and the limit speed is higher than that of the thrust cylindrical roller bearing because the rolling bus and the raceway bus of the washer converge at a certain point on the axis line of the bearing.New domestic modelsOld domestic modelInner diameter (mm)Outer diameter (mm)Width(mm)Cr(kN)Cor(kN)Grease lubrication speed (r/min)Oil lubrication speed (r/min)Weight (kg)294169039416801705446813802000–5.9129412903941260130422938542700—2.61294139039413651404534410002500—3.342

One of the largest aspects of the needle curler bearing is the sketch of the needle roller. The needle roller has a smaller diameter than different sorts of rolling elements, so it can obtain a greater load carrying capability in a constrained space.

Thrust roller bearings are used to bear axial and radial combined loads dominated by axial loads, but the radial load shall not exceed the axial load55%. Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher speed and aligning performance.29000, type bearing rod for the asymmetric spherical roller can reduce the relative sliding of the roller and raceway in the roller, and the roller is long, large diameter, the number of rollers, high load capacity, usually using oil lubrication, individual low speed can be grease lubrication.

Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy loadRolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down.

Structural features: The roller inside the cross roller bearing is combined in a cross arrangement, which makes the bearing able to withstand both radial and axial loads. There is a certain gap between the inner and outer rings, which can make the bearing maintain high rigidity when it is subjected to high torque load, and also has good rotation accuracy and stability. The design of the seal ring and cage of the cross roller bearing is also very important, which can effectively prevent dust and foreign matter from entering the bearing interior and extend its service life.

Rotary bearing is an important mechanical component used to support and rotate shafts, which is usually used in industrial equipment, ships, automobiles and construction machinery. It is mainly composed of an inner and outer ring, a rolling body and a cage, and realizes the rotation and support of the shaft by rolling between the inner and outer rings of the rolling body. The design and selection of rotary bearing have an important influence on the stability, reliability and operation efficiency of the equipment.
