Effectively below are 4 critical considerations when selecting to lubricate a bearing:How frequently does one re-pack bearings? Ever questioned whether or not you are carrying out it right? Effectively right here are four essential considerations when selecting to lubricate a bearing:

Lubricant alternative

Volume of lubricant to be shipped

Software tactic

Software Frequency

There are actually a lot of distinctive methods to use the grease to some bearing, and thoughts vary regarding which strategy is very best. Consequently, the very best angle could be to utilize rather a handful of strategies to acquire a technique that defines default values, which may then be fine-tuned, determined by comments from visible inspections, running temperature, ultrasonic instrumentation as well as other aspects.

Due to the inconsistency of performing predicament and device layout, it could be impractical being precise with no introducing the condition-based element into the formulation. Condition-based lubrication should really sort aspect of any world-class program.

Grease Option

When re-packing a bearing, a very good start line is choosing the proper grease. Just selecting the best-quality grease just isn’t as essential as deciding on the right grease for any established application.

Additive requirements

Base oil type

Thickener form and concentration


Dropping issue

Operating-temperature vary.

When most end users accept grease good quality, many never halt for making certain the right lubricant is being used to be certain economical lubrication.

The amount of grease to work with

Certainly one of the greater essential but ordinarily slipshod methods of your greasing method is the amount grease to employ to lubricate a bearing. “However a lot it takes” just isn’t greatest practice! There are some ways of estimating the correct relubrication volume. SKF contain the subsequent facts to determine the correct volume:

Gp = 0.005 * D * B


Gp = grease replenishment quantity (gm)

D = bearing outside the house diameter (mm)

B = full bearing width (mm) This technique provides constructive benefits, but you needs to be mindful that it does not account for differences in bearing housings and application points; assuming the grease is included for the ideal site. It truly is also under no circumstances instances doable to understand the quantity and ailment of previous grease while in the housing in the time of reapplication.
