2. The diameter of the inner (outer) cylinder of a row of balls in the inner (outer diameter) bearing of the ball set.
3. The diameter of the inner (outer) cylinder of a row of rollers in the inner (outer) diameter radial contact roller bearing of the roller set.
4. The gap between the two theoretical end faces of the bearing nominal width ferrule (the opposite side of the washer) is used to limit the width of the radial bearing (thrust bearing height).
5. The bearing practice width is the spacing between the axial line of the radial bearing and the intersection of the two tangential planes of the ferrule practice end face that limits the bearing width. The inner ring end face and the outer ring end face limit the bearing width.
6. Bearing practice width error bearing difference between practice width and nominal width.
7. The radial runout of the inner ring of the complete bearing is in the different angular orientation; the difference between the maximum and minimum radial spacing between the outer bore and the opposite outer ring. The angular orientation at or above the point The roll body at the two ends should be in contact with the inner surface of the inner or outer ring raceway or the inner ring reverse rib (tapered roller bearing), that is, the bearing parts are in a normal relative orientation.
8. The radial runout of the outer ring of the complete bearing outer ring is in a different angular orientation; the difference between the outer diameter of the outer diameter and the inner and outer radial ring is fixed. The angular orientation at the above point or adjacent to the two ends The roll body should be in the inner or outer ring raceway or the inner ring reverse rib (tapered roller bearing). The inner surface touch is the normal relative orientation of the bearing parts.
9. The inner ring end of the complete bearing faces the raceway of the raceway. The Sia inner ring is in a different angular orientation; the radial spacing from the inner ring axis is equal to the half of the inner ring raceway touch diameter; the inner ring reference end face is opposite to the outer ring. The difference between the maximum and minimum axial spacing between the fixed points of the circle. The inner and outer raceways should touch all the rolling bodies.
10. The outer ring end of the complete bearing faces the beating of the raceway. The outer ring of the Sea is in a different angular orientation; the radial distance from the axial line of the outer ring is equal to the half of the diameter of the outer ring raceway; the outer ring reference end face is opposite to the inner The difference between the maximum and minimum axial spacing between the fixed points of the circle. The inner and outer raceways should touch all the rolling bodies.
11. The end face facing the inner hole of the jump Sd in the radial distance from the inner ring axis line is equal to its raceway connection

Product introduction
Type CH4 Adsorbent
Coal bed methane (CBM) is a kind of clean energy with high calorific value and no pollution.
Its main component is methane, which is very rich in resources.
In order to ensure the safety of coal mining, coal bed methane extracted from the mine is mixed with a large amount of air, resulting in 20% to 40% low concentration of coal bed methane, and containing less than 18% oxygen, causing safety hazards for methane concentration, and removing more than 60% nitrogen, which increases considerable difficulty for adsorbent.
By using this adsorption, the mixture of CH4 and N2 from 30% to 70% can be enriched to over 92% with a recovery rate of more than 31.6%, and the mixture of CH4 and N2 from 50% to over 95% with a recovery rate of more than 47%.
CMSCH4 concentration CBM methane adsorbent has the following characteristics:
Effective purification of methane content of coalbed methane is more than 5% (extremely high methane content, obvious effect).
2. It has very strong deoxygenation and explosion-proof functions to ensure the safety of PSA in the process of coal bed gas enrichment;
3. Adsorption at room temperature and low pressure, low energy consumption;
4 radix can be deoxygenated at the same time of CH4 and N2 separation without prior deoxygenation or methane enrichment, with obvious low cost and economic benefit.
