Hi Bearing selection for low-speed applications:

Low-speed applications present challenges for designers who must specify bearings, just as high-speed applications do. (Uneven wear from intermittent motion, torque uniformity and vibration resistance are a few examples.) A new white paper from Kaydon Bearings, an SKF Group company, looks at the type of bearings typically used in low-speed applications and reviews 10 key performance requirements that designers should consider when specifying them.

SKF Explorer spherical roller bearings:

Setting the industry standard – again.

You know that quality bearings are critical to your operation’s success, but what if a bearing was so good, it could last twice as long as the one it replaces? 

So good that it could reduce energy costs, cut lubricant use, and even allow you to run your machinery faster and cooler? 

The benefits to your operation would far outweigh the cost.

Upgraded SKF Explorer spherical roller bearings are just that good, delivering twice the life under contaminated and poor lubrication conditions.

Excellence in design and performance,

Hi Workplace Noise: Dangers, Standards and Remedies;

Hi Workplace Noise: Dangers, Standards and Remedies;

If you have ever visited a commercial warehouse, factory floor, airport or construction site, to name only a few common workplace environments, you probably experienced some serious noise levels first-hand. 

While momentary exposure may not have done you any harm, employees who must spend hours at a time around noise risk permanent hearing damage. 

That's why OSHA (Occupational SAFETY AND HEALTH Administration) and other standards for hearing protection exist -- and why businesses must do everything possible to adhere to those standards.

Anatomy of a Noise Problem;

The human ear is lined with an array of tiny, delicate hairs known as cilia. The cilia vibrate in response to sound waves, and this vibration enables the brain to interpret the information as the everyday noises, music or other sounds that surround us every day, but when the cilia are exposed to excessive levels of sound over a period of time, they can lose their ability to vibrate normally, a condition that may be temporary at first and then become permanent with prolonged or multiple exposures. 

The results may include tinnitus, an annoying condition that conveys a CONSTANT RINGING or stuffiness in the ears, and temporary or permanent hearing loss. Unfortunately, many people who can simply avoid exposure to loud noise in their personal lives have no such option at their jobs, where they may be forced to endure loud noise eight or mores hours each day for years.

What You Can (and Should) Do;

Governments have long understood the need to protect employees from various forms of danger in the workplace, including the danger of hearing damage. 

The Occupational SAFETY AND HEALTH Administration (OSHA), a division of the United States Department of Labour, has noted that noisy environments not only cause hearing damage, but they can also make communication between workers impossible -- an invitation to accidents -- and create an unduly stressful environment. 

OSHA regulations therefore call for workplaces to protect workers against noise exposure exceeding 85 decibels in a eight-hour period. 

"(For reference, a heavy truck at 15 meters produces about 90 decibels, while a jack hammer can produce 100 decibels.)"

You can determine your workplace's noise level by measuring it with a device that displays an A-weighted decibel reading, the type of reading that corresponds most closely to human hearing perception. 

Even reducing the noise level by just three decibels effectively halves the impact on the ears.

If you find that your business produces too much noise for comfort, safety or health, don't panic;

you can implement a variety of measures to maintain a healthier noise level in your workplace. Sometimes the environment itself can be modified; 

for instance, an old, noisy piece of equipment can be replaced with a more efficient, quieter one, or an acoustical barrier can be placed between the noise source and the employees. 

In cases where this is impossible, employers can issue noise-reducing earplugs, headphones or earmuffs and require workers to use them properly and consistently as a condition of employment.

Hi Mechanical! 3 Ways to Increase the Life Span of Your Hydraulic Equipment!!!1!2!!3!!!

Hi Mechanical! 3 Ways to Increase the Life Span of Your Hydraulic Equipment!!!1!2!!3!!!

Like it or not, hydraulic systems are part of modern-day life.  You probably rely on hydraulics for your power brakes and power steering. Hydraulic systems tend to be fairly complicated, and maintaining and repairing them can be difficult.  Luckily, there are lots of things that you can do to improve the longevity of the hydraulic systems that you use on a daily basis. Even though there are thousands of applications of hydraulic machinery, they tend to follow some basic patterns of predictability when it comes to malfunctioning parts.  Here are three simple ways you can increase the life span of your equipment. 1. Keep Track of Hose Issues, and Replace or Repair Where Necessary; Hoses don't tend to break unless they are very old or worn.  There are several ways in which hoses break down, and each comes with its own set of circumstances. Old hoses tend to have cracks that start to form on the inside and outside of hose walls.  One of the major contributors to hose breakdown over time is the presence of ozone.  Ozone is a chemical that reacts with hose material, diminishing the life expectancy of the hose.  You can prevent this by using ozone-resistant hoses in the future. Hoses with abrasions indicate some sort of mechanical friction against the hose.  This is likely due to your hoses not being secured properly.  The best way to secure a hose to something is to use hydraulic hose clamps. These clamps come in all shapes and sizes, and are capable of fastening hoses to almost any surface. You might also consider buying abrasion-resistant hosing, especially is this is a repetitive problem. Abrasion-resistant hosing will not fix the problem, but it can greatly increase the time between replacements. Tightly bent hoses will often break down more quickly than straight hoses.  They are also known to form kinks over time. For these reasons, you can buy hosing that can be bent up to 180 degrees.  Since it is made to handle this type of stress, it lasts a lot longer in bent form than other hose options. 2. Install Versatile Couplings; Some couplings are extremely sensitive. When installing them, you can easily apply the wrong torque, resulting in a leaky or malfunctioning connection.  If you encounter this, you will definitely have to replace the coupling.  Consider installing a coupling that is designed to handle improper torque so that you don't find yourself having to replace the part again soon. When purchasing couplings, try to pick a manufacturer that offers a variety of options.  Hydraulic parts are manufactured all over the world, because of that, there are lots of different types of parts that just don't fit together.  By purchasing from a manufacturer that sells all types of fittings and hoses, you can be sure to find what you are looking for. 3. Use Quality Part Replacements; When hoses or other parts need to be replaced, the time that the machinery is not running during repairs is referred to as 'downtime', because time is MONEY, minimizing downtime is important to reduce costs and speed production. Gates Programs recommends replacing hoses, clamps, and fittings with beefier parts that have longer life spans in order to reduce downtime.  The less you have to REPLACE PARTS, the less downtime your equipment will require for proper function. There are lots of things that can go wrong with a hydraulic system.  However, by properly identifying the malfunctioning or missing parts, and replacing them with more durable versions, you can decrease the amount of maintenance your hydraulic system requires.  Don't buy cheap REPLACEMENT PARTS for your hydraulic system. If you do, you could end up paying for it in repairs down the road.
