Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also withstand axial loads in either direction. With high radial load capacity, it is especially suitable for work under heavy load or vibration load, but can not bear pure axial load. The raceway of the outer ring of this type of bearing is spherical, so its self-aligning performance is good, and it can compensate the coaxiality error.

There are two rows of symmetrical spherical rollers. The outer ring has a common spherical raceway. The inner ring has two raceways inclined at an angle to the bearing axis. It has good self-aligning performance. When the shaft is bent or installed out of center The bearing can still be used normally. The self-alignment varies with the bearing size series. Generally, the allowable self-aligning angle is 1 ~ 2.5 degrees. The load capacity of this type of bearing is large. In addition to the radial load, the bearing can also withstand. Axial loads acting in both directions have better impact resistance. Generally speaking, the working speed allowed for spherical roller bearings is lower.  WSBC 24024 MB bearings online , if you are interested , pls click here : 

In the application process of bearings, if corrosion occurs, it will have a very adverse effect on the industry, so it is necessary to strengthen the anti-rust measures for spherical roller bearings. There are two main aspects in bearing anti-rust, one is anti-rust treatment in process, and the other is anti-rust treatment in finished product.

Management of antirust technology for spherical roller bearings

In order to ensure that the anti-rust process can be carried out seriously, the technical department formulates specific evaluation rules according to the process requirements, and converts the composition value to evaluate the production plant. The first-level anti-rust management personnel conduct monthly process discipline inspection on the production plant. The management of cooling water, anti-rust liquid, cleaning fluid, anti-rust oil and the rust rate, cleanliness and oiled packaging of the finished bearing are The management level of the rust staff and the monitoring situation of the monitoring project are subject to a comprehensive inspection, assessment and scoring, and the assessment results are issued to the production plant. A regular meeting of rust prevention personnel is held once a month to summarize the company's monthly inspections and problems, and to propose improvement measures to rectify within a time limit; at the same time, it also provides opportunities for rust prevention personnel to communicate and learn from each other. Establish a rust management work network, so that the rust prevention work has a good management foundation.   

Management of anti-rust auxiliary materials for spherical roller bearings

The quality of the anti-rust material for spherical roller bearings directly affects the quality of product processing. Therefore, when selecting anti-rust materials, first conduct physical and chemical performance testing according to the quality requirements, and then conduct a pilot test after passing the test. . The selected anti-rust auxiliary materials will be strictly tested according to the quality standards of different materials after entering the factory. During the use process, the anti-rust material and the prepared solution shall be tested regularly to ensure that the concentration and proportion of the solution meet the technological requirements and reach the performance. The establishment of a complete material acceptance system and quality acceptance standards provides a reliable guarantee for good anti-rust management.  Wuxi Spark Bearing Co.,Ltd supply different type roller bearings . 

Spherical roller bearings are coated with anti-rust oil and sealed to avoid the influence of atmospheric environment during storage and transportation, which may cause rust and mildew and affect the performance.  

The finished spherical roller bearings are washed twice by kerosene mechanical spraying, mechanical spraying anti-rust and lubricating dual-use oil, and polyethylene sealed packaging.   

Before kerosene spraying and anti-rust lubricating dual-use oil spraying, use filter elements that meet the process requirements to ensure the cleanliness of the finished spherical roller bearings. The oil tank and machine tool are thoroughly cleaned once a month.  

When inspectors and assembly personnel touch the finished parts and bearings, liquid gloves should be applied to avoid corrosion due to hand sweat.   

Handle and store the finished spherical roller bearings during storage to avoid damage to the packaging.  

The assembly room and finished bearing storage room should be dry, clean and free of pollution sources.
