Starting and running torques 7.1 Preload and starting torque for angular contact ball bearings Angular contact ball bearings, like tapered roller bearings, are most often used in pairs rather than alone or in other multiple bearing sets. Back-to-back and face-to-face bearing sets can be preloaded to adjust bearing rigidity. Extra light (EL), Light (L), Medium (M), and Heavy (H) are standard preloads. Friction torque for the bearing will increase in direct proportion to the preload. The starting torque of angular contact ball bearings is mainly the torque caused by angular slippage between the balls and contact surfaces on the inner and outer rings. Starting torque for the bearing M due to such spin is given by, M=Ms · Zsina (mN · m), {kgf · mm} .................

Access to natural light and views is a positive factor on the

employee experience. Employees say that access to natural light and views improves their overall happiness and well-being (78%), work satisfaction (73%), work performance (70%) and organizational commitment (54%). Absence of natural light and views hurts the employee experience.

Over a third of employees feel that they don’t get enough natural light in their workspace. 47% of employees admit they feel tired or very tired from the absence of natural light or a window at their office, and 43% report feeling gloomy by the lack of light.

Prolonged technology use makes employees want a view/natural

light more. Over half of employees say that prolonged screen use leads to eyestrain or headaches at work. 73% agree that the longer they use their technology devices, the more they desire a visual break such as taking a walk or glancing at the view outside.

In a newly released study by Future Workplace entitled “The Employee Experience,” over half of the 1,614 North American employees surveyed said natural light and views of the outdoors were their most important office perks, ranking higher than onsite cafeterias, fitness centers, medical care and childcare.

Key findings of The Employee Experience study include:

MethodologyResearch findings are based on a survey

conducted by VIGA, fielded across the US and

Canada between June 8th–11th, 2018. For this

survey, 1,614 employees were asked about their

views regarding workplace environment and

experience with their current employer. The

study targeted full-time employees who work

across different sectors and in organizations

of different sizes. Respondents were recruited

through a number of different mechanisms,

via different sources to join the panels and

participate in market research surveys. All

panelists had passed a double opt-in process

and complete on average 300 profiling data

points prior to taking part in surveys.
