On November 26th, according to the released JD Power 2015 China Vehicle Reliability Study SM (VDS), vehicle reliability has made great progress this year, close to the mature market level. The reliability improvement of independent brands is the most obvious, and the gap with international brands is getting smaller and smaller. This year is the sixth year in which JD Power has conducted vehicle reliability research in China. The study measures problems encountered by car owners during the past six months in the 37-48 month period, including eight problem categories (engine/shifting, body appearance, driving experience, configuration/manipulation/dashboard) 202 problem symptoms for audio, entertainment/navigation systems, seats, air conditioning systems and body interiors. The overall reliability is measured by the number of problems per 100 vehicles (PP100), and the lower the score, the better the quality. Main findings: Overall vehicle reliability has improved, approaching mature market levels: the average number of problems in 2015 was 156 PP100, a reduction of 37 PP100 compared to 2014 (193 PP100). Continued advances in vehicle reliability have brought China closer to the mature US market. Compared to the same period, the gap between China's vehicle reliability and the US is 9 PP100. · The progress of domestic brands is the most obvious: according to the country of origin of the brand, the independent brands have made the most progress, and the number of problems has decreased by 48 PP100. In addition, the gap between independent brands and international brands continues to narrow, from 43 PP100 in 2014 to 27 PP100 in 2015, and the engine/transmission system problem (16 PP100) accounts for nearly 3/5 of this gap. · Reliability significantly affects customer loyalty: If one or more problems are encountered, the car owner's loyalty declines by nearly half, only 16% of the car owners said they would "really" recommend the same model, 5% of the owners said they would buy the same Brand, and this proportion is 28% and 10% among the owners who have no problems. · The problem of failure persists: Although the reliability of the vehicle has improved significantly, the problem related to the fault is still a drawback faced by the Chinese market. Of the problems mentioned by US car owners, 33% are related to failures (the rest are design-related); among the problems mentioned by Chinese car owners, 55% of the problems are related to failures (the rest are design-related). · The number of problems with Korean brand cars is the least: the average number of problems for Korean brands is 130 PP100, which is 30 PP100 less than the average number of problems in the mainstream car segment (160 PP100). Dr. Mei Songlin, vice president and managing director of JD Power China, said: “The overall vehicle reliability has made significant progress compared to last year, indicating that the huge investment and efforts in the manufacturing field will ultimately pay off. However, automakers should continue to work. Quality and reliability, because quality and reliability are extremely important to customer loyalty. Over the years, automakers have paid special attention to new car quality issues within 90 days of car purchase, but now is the time for car manufacturers to prioritize reliability." XJ Juan, director of automotive market research at JD Power in China, said: "In terms of the proportion of fault-related issues, the difference between the Chinese market and the US market indicates that manufacturing quality still has room for improvement in China. Moreover, as Chinese car owners become more Get used to their vehicles and they will probably start to mention more design-related issues." 2015 China Vehicle Reliability Research Ranking Porsche (97 PP100) ranked first in vehicle reliability among luxury car brands, Mercedes-Benz (103 PP100) and Lexus (107 PP100) ranked second and third respectively. MINI (110 PP100) and Volkswagen (110 PP100) ranked first among mainstream car brands. Renault (113 PP100) and Subaru (117 PP100) ranked second and third respectively. In the 12 award-winning market segments, Beijing Hyundai's models won three market segment awards. Mercedes-Benz ranks first in both market segments. The winning models in each market segment are as follows: · Mini Car Segment: Geely Panda · Compact high-end sedan segment: Hyundai Rena · Medium-sized basic car segment: Honda Fengfan · Mid-size car segment: Kia Cerato · Medium-sized high-end economy car segment: MINI · Medium-sized high-end car segment: Hyundai Sonata · Compact luxury sedan segment: Mercedes-Benz C-Class · Midsize luxury car segment: Mercedes-Benz E-Class · Medium SUV segment: Hyundai Tucson · Medium-sized luxury SUV segment: Lexus RX · Large luxury SUV segment: Audi Q7 ·Micro-customer segment: Wuling Light The 2015 China Vehicle Reliability Study is based on the evaluation of 17,534 car owners who purchased cars between May 2011 and August 2012. The research report analyzed 21 market segments, covering a total of 160 passenger car models of 59 brands. Data collection was conducted in May and September 2015 in 46 major cities across China. A linear-motion bearing or linear slide is a bearing designed to provide free motion in one direction. There are many different types of Linear Motion Bearings.

Motorized linear slides such as machine slides, XY tables, roller tables and some dovetail slides are bearings moved by drive mechanisms. Not all linear slides are motorized, and non-motorized dovetail slides, ball bearing slides and roller slides provide low-friction linear movement for equipment powered by inertia or by hand. All linear slides provide linear motion based on bearings, whether they are Ball Bearings, dovetail bearings, linear Roller Bearings, magnetic or fluid bearings. XY Tables, linear stages, machine slides and other advanced slides use linear motion bearings to provide movement along both X and Y multiple axis.
