How to Determine the Scale Parameters of SKF Imported Bearings
Source: China Bearing Network | Time: 2013-07-24
When selecting SKF imported bearings, it's essential to consider various factors such as internal bore dimensions, operating life, static load safety factor, and economic efficiency. The scale calculation is a crucial step before finalizing the bearing selection, especially when the machine layout or equipment constraints are involved. The scale calculation involves comparing the actual load on the bearing with its static load capacity. This is particularly important when the bearing is stationary or rotating at very low speeds, where the primary concern is the risk of plastic deformation in the raceway and rolling elements. In such cases, the safety factor against excessive deformation must be carefully calculated. Most SKF bearings operate under dynamic loads, where the inner and outer rings move relative to each other. In these situations, the scale calculation helps assess the safety factor against early fatigue failure of the rolling elements and raceways. This ensures that the bearing can withstand the expected operational stresses over its intended service life. In special applications, DIN ISO 281 standards can be used to calculate the nominal life of the bearing, providing an estimate of how long it can function effectively under specific conditions. Properly calculating the bearing parameters not only enhances performance but also maximizes cost-effectiveness. Understanding the correct scale parameters is vital for ensuring optimal bearing performance and longevity. Whether you're working with standard or custom applications, accurate calculations help avoid premature failures and reduce maintenance costs.

The [Screw-Locking" tangless insert provides self-locking torque on the male member by a series of [chords" on one or more of the insert coils. With tangless inserts, no loose tangs are left behind, and they are the solution when foreign object debris (FOD) cannot be present in critical applications.
