Klüberplex BEM 41-132 vs BEM 34-132: selection guide
On this page
How do BEM 41-132 and BEM 34-132 differ?
Klüber describes BEM 41-132 for high-temperature and long-term rolling-bearing lubrication. Its BEM 34-132 guidance addresses highly loaded applications and protection under vibration and oscillation. These application descriptions help frame a selection review; the bearing’s actual conditions and equipment requirements determine which product to specify.
Where their documented uses differ
| Product | Manufacturer description | What to investigate for your application |
|---|---|---|
| Klüberplex BEM 41-132 | A grease for high-temperature and long-term lubrication of rolling bearings, based on synthetic hydrocarbon oil, mineral oil and a special lithium soap. | Actual bearing temperature, speed and lubrication interval. |
| Klüberplex BEM 34-132 | A speciality rolling-bearing grease with published guidance for highly loaded applications and protection under vibration and oscillation. | Load, movement pattern and periods of vibration while stationary. |

Klüber also describes wear and corrosion protection for these products. Those descriptions do not provide a direct comparison of performance in your bearing. Numerical limits and test results should come from the current product information, with the test conditions kept alongside the values.
Information needed for a selection review
Identify the bearing and its operating cycle. Record whether the load rotates continuously, oscillates or remains stationary while the surrounding machine vibrates. Include operating temperature, speed, exposure to process media and the lubrication system.
For BEM 41-132, check the high-temperature and grease-life requirements against the product information and the equipment instructions. For BEM 34-132, describe the vibration or oscillation conditions that motivated the enquiry.
A laboratory test result alone does not establish a field relubrication interval. Use the machine builder's instructions and an application-specific assessment.
Changing from one product to the other
Get a defined changeover procedure before adding a different grease to the housing or centralized system. Confirm whether cleaning is required and which fill quantity and monitoring procedure apply.
Record the exact product name, including any suffix on the package. Similar names in the same family should be checked individually rather than treated as the same formulation.
Requesting a quotation
KOEED has product listings for both BEM 41-132 and BEM 34-132. Send the required product, packaging and quantity, together with any documentation requirements. Confirm the offered pack size and current availability in the quotation.
Which one is better?
The answer depends on the bearing and its operating conditions. The manufacturer descriptions support different selection questions; they do not identify a universal winner.
Can I use the same maintenance interval?
Confirm the interval as part of the approved change. Keep the previous maintenance record, but do not assume that it transfers unchanged to a different lubricant.
Confirm the full BEM product designation
Send BEM 41-132 or BEM 34-132 as specified, together with the pack size and quantity. Include any suffix on the existing package and the documents required with delivery.
