(2) The rolling bearing grease is too small, too much or has iron scraps and other impurities. The capacity of the bearing grease should not exceed 70% of the total volume; those with impurities should be replaced.
(3) The shaft and the bearing cooperation are too tight or too loose. When overtightening, it should be ground from the head; when it is too loose, the shaft should be set.
(4) The bearing and the end cap cooperate too tightly or too loosely. The bearing chamber is machined when it is too tight; when it is too loose, the steel sleeve is set in the end cover.
(5) Poor installation of the two caps or bearing caps of the motor. Install or flatten the end caps or bearing caps; tighten the screws.
(6) The belt is too tight or the coupling is not properly installed. Adjust the belt tension; proofread the coupling.
(7) The sliding bearing lubricant is too little, there is impurity or the oil ring is stuck. It should be like refueling or replacing new oil; repair or replace the oil ring.

Meniscus cylinder Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus cylinder Lens is used to increase the focal length of another Cylindrical Lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the cylindrical lens.
Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens.
Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
