Application scenarios include increased loading, frequent starts, shock events, unusual wear and changes to support arrangements. Prepare load directions and values, peak durations, operating cycles, speeds, drawings and damage photographs. This guide organises application information and does not promise equipment capacity or bearing life.
Describe the load as an operating condition
Identify the equipment, bearing position and load source. Distinguish steady operation, starting, stopping, reversal, blockage and occasional shock. Record radial and axial directions, values, units and the measurement or calculation conditions.
For variable loading, provide duration, peaks and frequency within an operating cycle. Equipment power or a description of heavy duty alone is not converted directly into a bearing load.
Read parameters with the support structure
Read dimensions, basic dynamic load rating and basic static load rating as separate fields for the complete designation, keeping their units. Catalogue ratings support a technical comparison; they do not directly establish an equipment load limit or a site safety factor.
Submit support spacing, installation details, shaft shoulders, housing drawings and maintenance records for associated parts. Category illustrations explain structures and do not recommend a bearing for a particular heavy-load machine.
Connect damage records to operating events
Record when and where symptoms first appeared, including noise, vibration, temperature changes and inspection findings. Photographs should cover the overall bearing, raceways, rolling elements, cage and installation location, with the condition before and after removal identified.
Place overload events, lubrication maintenance, component replacement and operating changes on one timeline. A local photograph alone does not establish a failure cause or a life prediction.
Define the evaluation and verification scope
Organise structural comparisons, missing load information, installation inspection items and subsequent verification steps. Where a candidate designation is considered, compare dimensions, structure, loads, lubrication-specific speeds and installation requirements individually.
This guide does not promise an uncalculated service life, load increase or reduction in downtime. Discuss any change together with equipment requirements and a site verification plan.

Structure illustrations are references, not application recommendations. Read parameters for the complete designation.
