广泛应用于传感器，室外测量仪表，水平仪器，标线仪器，红外线仪器，重力摆投线仪 ，电安平投线仪，自动扫平仪 ，垂准仪， 激光投线仪 ，重力摆系列激光投线仪 ，激光垂准仪，全自动激光扫平仪，C2000-A全自动血凝仪，镭射墨线仪，激光扫平仪，激光垂准仪，镭射旋转仪，激光测距仪，微波漏能仪，电导仪和溶解臭氧仪器和光学仪器路基测量仪等。 693 bearings are widely used in sensors, outdoor measuring instruments, level instruments, marking instruments, infrared instruments, gravity pendulum line gauges, electric safety level line gauges, automatic levelers, plummets, laser line gauges, gravity pendulum series lasers Casting line, laser plummet, automatic laser leveler, C2000-A automatic hemagglutination meter, laser ink line meter, laser leveler, laser plummet, laser rotation meter, laser rangefinder, microwave leak meter , Conductivity meter and dissolved ozone instrument and optical instrument roadbed measuring instrument.
These instrument bearings produced by Shanghai Yuwei Bearing Co., Ltd. have high precision, low friction torque and low noise. Yuwei instrument bearings have a long life and high reliability. Due to the particularity of the parts used, the bearings are generally lubricated by solid lubrication or thin oil lubrication.
Yuwei Instrument Bearing in the long-term use process to summarize the experience, the reference
1) Generally adopt ABEC5 grade precision instrument bearing;
2) The friction torque of the bearing is required to be small; it is called a miniature frictionless bearing.
3) Due to the small load, the instrument and bearing need not consider fatigue and life, but there are certain requirements for noise; the instrument and meter industry generally requires highly sensitive miniature bearings.
4) When selecting the bearing fit, it is not necessary to consider the effect of load on life, but mainly the thermal expansion of the shaft and the impact of shaft assembly, so the fit with a smaller interference amount should be selected;
5) The working clearance of the bearing is small or zero, but the friction and temperature increase due to negative clearance should be avoided.
Although Yuwei Bearing has experience in the instrument and bearing industry and its timeliness is also high, the current instrument and meter market is in a relatively stable period. The emergence of some new instrument and meter companies has higher requirements for instrument and bearing.
From 2005 to 2010, the instrumentation market was very popular, especially in Suzhou, Changzhou, Tianjin, and Beijing in Jiangsu Province. The booming instrumentation market brings opportunities to the instrumentation and bearing market. Almost to the point where, regardless of the price, just ask if there is a spot. The price of 693 bearings (3 * 8 * 3) has reached the volume price of 3.5. In addition, many enterprises have started mass production. For this reason, a bearing company specializing in instrumentation has appeared in Nantong. Around July 2010, the price has reached 1.3 or even 1.00 yuan. Problems have also arisen, many bearing companies have lowered their prices, and some companies have shipped below the cost price. The result is to find a way on raw materials-the quality of the bearings is not stable.
The above problems are also a result of market development. Therefore, Yuwei also learned from the above. Following the market, it eventually hurt its own feet by moving stones. The market is large enough to make products suitable for the market and high-end instruments in the instrument industry.
