Exposing the myths around bearings – ttv GmbH – Your Choice for Sealing and Bearing

The wheels of a market turn on bearings, so why do the wheels frequently vibrate, clatter, squeak, drag, and get too hot? Bearings can stop working for lots of reasons. So, here are some common myths many people think about, which are not entirely true. We are the prime manufacturer of sealing and bearing products in Germany, and you can also check these products here: ttv GmbH – Products Overview.

  1. Bearings must not be hot to the touch.

Regular bearing operating temperature levels can vary from 80 to 150 F, but particular applications might run greater or lower. Many bearings are ranked for -20 to 220 F but can be provided with unique grease, seals, or heat supporting procedures that permit them to run at greater temperature levels.

Since excess grease increases drag and friction in the bearing, bearings generally run hotter at best or start-up after relubrication. Spikes approximately 50 F are regular at start-up and 30 F after relubrication. As the rolling aspects purge excess grease through the seals, the bearings go back to steady-state temperature levels.

  1. Larger bearings are always much better.

Larger bearings with a greater load capability might show a greater tiredness life. Still, if the load does not attain the minimum requirement, the rolling aspects can skid along the raceway rather than rolling. This can cause heats, extreme wear, lubrication breakdown, and bearing failure.

  1. Relubrication as soon as a year gets over

Start by examining the bearing producer’s lubrication suggestions. By contrast, an installed ball bearing in a gently filled, low-speed, clean environment might do great with relubrication at 12- to 24-month periods.

  1. If needed, you can strike a bearing with a hammer to place it.

Never ever strike a bearing straight. A hammer blow can produce damages in the raceway that can cause sound and considerably minimize the life of the bearing. If required, use a press to move the bearing.

  1. The existing TGP axis is the very best choice

It is far more crucial to understand the tolerance variety of the shaft to make sure that it satisfies the specs of the bearing maker to the size and roundness. Review of the suggestions of the bearing producer and procedure/define the right shaft size.

  1. Insufficient thinning can cause the bearing to move along the shaft

Use the “medium-total/ overall” guideline to tighten up the screws – tighten up the very first screw to half the suggested pressure, the 2nd screw to the overall pressure and return to the very first screw and use to the overall pressure.

  1. Bearings must not be hot to the touch

Many bearings can stand up to -20 to 220 ° F. But, and they can be provided with a unique grease, seals, or temperature level stabilization procedures that allow them to run at greater temperature levels.

  1. Bigger bearings are constantly much better

Bigger bearings with a big load capability normally have a longer life process; but, if the load does not satisfy the minimum requirement, the rolling components can move through the rolling rather of rolling. This can trigger temperature level boosts, extreme wear, lubrication breakdowns, and bearing failures.
