The products of INA bearings in Germany include agricultural machinery industry, construction industry, hydraulic and wind engineering industry, construction machinery industry, machine tool and manufacturing machinery industry, material handling and packaging industry, port engineering industry, power tool industry, gearbox industry, semiconductor industry, pump and fan industry, industrial robot and automation industry, rubber, plastic and chemical industry, textile industry, tractor industry, woodworking machinery industry, etc. In these industries, German INA bearings have been widely used.

The posterior code in the supplementary code is used to describe some special structures of the bearing, which is placed after the bearing code. The commonly used supplementary codes of INA are as follows:

Description of the supplementary codes used in the size table These supplementary codes apply to bearings in the current standard and are part of the bearing designation (see size table) and cannot be used for other bearings.

a, b, c, e- these symbols have no clear meaning and are used to indicate certain design features as needed.

d- Split needle roller and cage assembly.

p- Bearing with sealing ring on one side.

PP- Bearings with sealing rings on both sides.

RS- Bearing with sealing ring on one side.

2RS- bearings with sealing rings on both sides.

TN- Plastic cage.

v- Sealed bearings.

x- Bearings and accessories whose dimensions have been changed to comply with international standards, this supplementary designation is only used during the transition period.

When the general structure is with spherical rolls, x is also represented as a support roller and a curved roller with a cylindrical surface.

z- One side of the bearing has a shield against the shield.

2z- Bearings with shields on both sides.

ZW - Needle roller and cage assembly, double row.

The content of the fifth part refers to the "latest domestic and foreign bearing code comparison manual".

Exquisite rolling bearing technology, advanced production plants, and superior quality standards have made INA bearings famous and enduring in the world. It has been well proven in millions of practical applications. INA bearings are reliable mechanical parts that combine cost and efficiency, INA bearings are reliable mechanical parts that combine cost and efficiency, and INA products are available in a variety of sizes for rotary and linear motion as well as various specialized technologies.

We provide a wide range of sizes for a wide range of specialized technologies, providing valuable technical support for designers in various industries.

Peel damage state.

When the bearing rotates under load, the raceway surface or rolling surface of the inner and outer rings presents a fishscale-like peeling phenomenon due to rolling fatigue.

Causes: Excessive load. Poor installation (non-linearity), moment load, foreign matter intrusion, water ingress. Poor lubrication, inappropriate lubricant Improper bearing clearance.

The accuracy of the bearing box is not good, the rigidity of the bearing box is uneven, the deflection of the shaft is large, and the development is caused by rust, erosion points, abrasions and indentations (surface deformation phenomenon). Measures Check the size of the load and re-study the bearings used Improve the installation method, improve the sealing device, and prevent rust during shutdown. Use lubricants with appropriate viscosity and improve lubrication methods.

Check the accuracy of the shaft and bearing housing. Check the clearance. Entrapment Injury Status The so-called entrapment is a superficial damage caused by the accumulation of micro-burns in the part of the sliding surface injury.

Linear scars in the circumferential direction of the slideway surface and rolling surface. Cycloidal scars on the end face of the rollers. Jamming of the torus face of the shaft near the end face of the roller.

Causes: Excessive load, excessive preload. Poor lubrication. Foreign body bites.

The inclination of the inner and outer rings, the deflection of the shaft. The accuracy of the shaft and bearing housing is poor. Measures Check the magnitude of the load.

Preloading should be appropriate. Improvement of lubricants and lubrication methods. Check the accuracy of bearings, shafts, and bearing housings.

Abrasions Damaged state.

The so-called abrasion is the surface damage that occurs on the raceway surface and the rolling surface due to the accumulation of micro-burns caused by the slippage of the rolling and the thermal rupture of the oil film; Produces damage with a rough surface with adhesion.

Reason: High speed, light load. Rapid acceleration and deceleration. The lubricant is inadequate.

Intrusion of water, improper pre-pressurization. Measures: Improved bearing clearance. Use lubricants with good oil film.

Improve lubrication methods. Improve the sealing device, improve the preload fracture damage state.

The so-called fracture refers to the fracture of a small part due to the impact or excessive load applied to the flange of the bearing ring or the local part of the rolling element; There is a noticeable partial detachment or overall crack.

Cause: Hit at the time of installation. The instantaneous load is too large. Poor use such as drops.

Measures Improve installation methods (use hot loading, use appropriate tools). Correct the load conditions. The bearings are installed in place so that the flanges are supported.
