Product Description:

TIANHE 2 23944-2CS sealed roller bearing are fitted with a large number of long symmetrical large-diameter rollers, capable of withstanding very heavy loads. Special structures of raceway surface as well as the best quality ensure spherical roller bearings the lowest friction including C and CA-bearing.

Compared with conventional spherical roller bearings, tianhe bearings run cooler. They are able to withstand heavier axial loads, or up to a higher speed.

Q:Maintenance method of plain bearing
Damage type, damage reason, treatment methodGlue bearing overheating, excessive load, or improper operation of the temperature control system failure 1, in sports such as bearing overheating, should immediately stop check, the best of the rotor continues to operate at low speed, or continue to supply oil for a period of time, until the Bush cold down so far. Otherwise, the Babbit on the Bush is glued to the axle neck because it is glued, so it is troublesome to repair2, to prevent insufficient lubrication or oil impurities, and the rotor is not installed3, scuffing damage of lighter bearings can be scraped, repair methods to eliminate, continue to useFatigue failure caused by unbalanced vibration, shaft bending and edge loading, overload, etc., lead to fatigue rupture of babbit bearings.
Q:What are plain bearings, roller bearings, roller bearings, needle roller bearings?
A rolling bearing (ROLLINGBEARING) is a precision mechanical element that reduces the friction loss between a running shaft and an axle seat to a rolling friction. Generally, the rolling bearings consist of the outer ring, inner ring, roller and cage. A type of bearing in which the journal rotates in a circular contact with a number of rollers usually mounted on the locating ring.
Q:What are the failure modes and design criteria for non liquid friction sliding bearings?
Failure form: wear, scuffing.Design guidelines: maintenance of the boundary membrane is not damaged, minimize the wear of bearing materials.Relative condition checking1 checking: PM = [p], to prevent excessive bearing abrasion;2 checking: PMV = [pv], in order to prevent the bearing temperature rise too high and glue and;
Q:How does a sliding bearing work?
High speed rotating, in the sliding bearing surface, if the lubrication film can be formed to separate the surface of the moving pair,
Q:What are the structural and functional differences between thrust bearings and radial bearings and conventional ball bearings and plain bearings?
Thrust bearings are called thrust bearings, which can bear axial load (axial thrust), such as some large vertical motors and machine tools.Radial bearings bear radial loads, and these bearings are the most widely used.The above two are two kinds of bearings according to the force direction.Journal bearings and rolling bearings.Plain bearings: plain bearings, both inside and outside the ring, there is no rolling body, usually made of wear-resistant materials. Often used in low speed, heavy load, but also useful at high speed; filling lubricating oil and grease. If the copper sleeve belongs to this low - grease, oil pump, water pump and some other high speed and large fan speed reaches 7, 8K conversion of lubricating oil, the small gap between the shaft and the sliding bearing oil film, so that the sliding bearing and the shaft will not damage and wear.Others, as lianjuan2008 said.
Q:What are the four types of commonly used sliding bearing alloys?
In fact, sliding bearing alloy is not limited to four categories, such as Jiaxing Solid Lubricating Bearing Co. Ltd production of self-lubricating bearing on the use of copper alloy, iron alloy, zinc alloy, Aluminum Alloy, composite materials, engineering plastics and other materials.
Q:On what occasions are plain bearings used?
1, the working speed is very high;2, requirements of the axis support particularly accurate occasions;
Q:How many kinds of bearings are there in sliding bearings? What's the function of each?
1, the gap between bearings and bearings. 2, bearings radial series gapThe first kind of clearance will cause the bearing or bush to be damaged, and the lubrication oil pressure will be reduced. The gap is too small, which will make the bearing or bearing load increase sharply and even burn (tile)The second kind of clearance is too big, the bearing will move back and forth in the radial direction, the whole machine is not stable, the gap is too small, so that the load of the machine increases
Q:Which one is good for sliding bearings?
Huanyu Bearing Co., Ltd. is the leading industry leader in the bearing industry. Professional production of various kinds of ball mill sliding shoe bearing and motor cover type spherical bearing with DQ series end, Z, ZQ, ZQK, ZQFY, ZWF, ZWFH series of spherical bearing seat type,
Q:This problem has been bothering me for a long time.
At the same time must pay attention to the cleanliness of bearings, bearings selection accuracy and the use of appropriate installation and maintenance tools. Bearings must be protected against contamination and moisture, and must be properly installed and lubricated. The design and arrangement of the state seal bearing and lubricant type and lubrication cycle, bearings, and even specialized Yang are performing similar roles. Mixed oils do not mix incompatible oils. If two incompatible oils are mixed, the consistency is usually soft and may eventually be destroyed by the loss of grease. If you do not know what kind of grease the bearings should have used, then remove the old grease from the inside and outside of the bearings before you add grease. According to the classification of oil temperature and identify the premise: the oil can according to their allowable working temperature to classification, oil viscosity and smooth to be affected by the operating temperature, bearing the operation at certain temperature will need to have accurate choice consistency and good lubrication result at the same temperature grease. Oils are made from a range of work temperatures that can be identified as low temperature (LT), medium temperature (MT), and high temperature (HT) oils. At the same time, there is a kind of grease called EP (extrusion resistance) or EM (extrusion and increase molybdenum disulfide), plus additives to enhance the strength of the lubricating film. If you choose the oil grease selection fault bearing damage to all defenses in vain, choose a grease base oil viscosity at the temperature when it can supply sufficient lubrication effect is very important, important is the viscosity affected by the temperature, with the temperature rise and fall, when the temperature is decreased when it is picked up.
