How to prevent premature failure of INA stainless steel bearings

Bearings in the process of use for various reasons, will cause failure problems, then what are the failures of stainless steel bearings? We classify the failure modes of rolling bearings. These forms are the most basic three forms of rolling bearing failure. There are many reasons for bearing failure. All the factors affecting the design and manufacturing process will be related to the failure of the INA bearing. It is difficult to judge by analysis. In general, it can be considered and analyzed in terms of both usage factors and internal factors.

Wear, poor lubrication, intrusion of impurities and dust can cause wear and tear, which causes the INA bearing to lose its rotational accuracy and fail, which is the external cause. We should pay attention to maintenance and cleaning.

When the bearing speed is low or intermittently oscillated, fatigue pitting does not generally occur. At this time, the bearing is often plastically deformed due to excessive static load or impact load, which causes the stainless steel bearing to fail. This is the problem of work intensity. It is necessary to first match the strength of the bearing, that is, what is the speed required for your work, and choose the bearing that matches it.

(1) Surface oxide layer

The surface of the steel under transient high temperature acts on the oxygen in the air and rises into a very thin (20-30 nm) thin layer of iron oxide. It is worth noting that the thickness of the oxide layer is corresponding to the test results of the total thickness of the surface-grinding metamorphic layer. This shows that the thickness of the oxide layer is directly related to the grinding process and is an important indicator of the quality of the grinding.

(2) amorphous layer

When the instantaneous high temperature of the grinding zone causes the surface of the workpiece to reach a molten state, the molten metal molecular flow is uniformly applied to the working surface, and is cooled by the base metal at a very fast speed to form a very thin layer of amorphous state. Organizational layer. It has high hardness and toughness, but it is only about 10 nm and is easily removed in precision grinding.https://www.supplyforever.com/

Technical parameters of TIMKEN bearings

TIMKEN bearings are designed for a combination of radial and axial loads. Single row bearings have a high unidirectional thrust capability. Some single-row TIMKEN bearings are specifically designed for a two-way installation for optimum performance. Double row Conrad bearings can withstand thrust in both directions.
The special geometry of the channel and shoulder of the TIMKEN bearing creates a ball contact angle that can withstand higher axial loads. Different designs have a range of contact angles from 20° to 40°. The contact angle of the TIMKEN bearing provides greater axial load capacity and a longer service life under axial and radial loads.
TIMKEN bearing:
Size range from 3 mm to 600 mm
Extended option
    Special coating for corrosion protection
Special seal design
Fafnir radial ball bearings use a universal design that allows relatively high speed operation under large load conditions. The TIMKEN bearing consists of an inner ring and an outer ring and has a cage with a set of precision balls.
Standard Conrad bearings have a deep groove structure that can carry both radial and axial loads in either direction. The maximum load type mainly supports radial load.
From ultra-light to heavy, it offers a very wide range of sizes. A variety of protective and sealing arrangements help protect internal bearing components and retain lubricant.
TIMKEN bearings are designed to meet the high speed, precision and hardness requirements of demanding machine tools. These TIMKEN bearings can be produced for the highest precision standards recognized by ABEC-7 to ABEC-9, the ball bearing industry.
Most ultra-precision ball bearings have a contact angle of 15° to 25° to accommodate different combinations of radial and axial loads. Special channel treatment and ball bearing design for the highest possible working speed.
Hybrid ceramic bearings are available with steel ceramics and ceramic balls to accommodate high speed and other demanding applications.
The ball spiral bearing is supplied in a complete package with a 60° contact angle and maximum ball compensation, suitable for high load and axial hardness requirements for most precision tool positioning.
