How do you use the pointer type push force meter you bought? Don't worry, Shanghai Shiheng Electronic Technology Co., Ltd. is a professional manufacturer of pointer push force gauges. For the use of the pointer type push force gauge, our company summarized the following point.
Analog push-pull gauge picture
Pointer thrust force meter using method 1), measuring the size of the force of the tool called dynamometer 2), according to the greater the spring tension, the principle of longer spring elongation made 3), before the measurement pointer measurement Force meter's measurement range (range) division value, to clear the division value, must also be zero.
4) In the actual measurement, the direction of the inner spring axis should be the same as the direction of the measured force.
5) When reading, the line of sight of the eye observation pointer should be equal to the score line.
6) When recording the results, both the number and the unit must be recorded.
7), clear range and division value, must be zero before use,
8) In the actual measurement, the axis direction should be consistent with the direction of the measured force.
9) When reading, the line of sight of the eye observation pointer is flush.
10) Record results include numbers and units.
11) Observation range: Observe the maximum scale value on the panel of the spring scale. Note that the force on the pointer dynamometer cannot exceed its range.
12), observe the minimum scale value: that is, how many cows each cell of the scale of the spring scale represents.
13), correction zero: see if the pointer is in the zero position, if not, you should adjust to the pointer on the zero scale line.
14) The pulling force is applied to the spring scale in the direction of the central axis of the spring.
15) Observe the pointer to indicate that the line of sight should be perpendicular to the tick mark.
NSK manufacture a full range of deep groove ball bearings. These bearings are the most common type and are used in a wide variety of applications.
Single-Row Deep Groove Ball Bearings
Pressed Steel Cages
Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used.
Machined cages are also used for high speed applications.
Extra Small Ball Bearings and Miniature Ball Bearings
Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can be further divided into the following five classes depending on their design details:
Standard type
Flanged outer ring
Extended inner ring
Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width.
Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed.
Maximum-Type Ball Bearings
Maximum-Type ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 6200 and 6300 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel.
