Stainless Steel Bearings: What the Grade Really Costs

A stainless bearing is usually three different stainless steels, and specifying one costs you exactly one column in the catalogue. SKF's own tables show the dynamic rating falling 16 to 23 percent while the static rating, the fatigue load limit and the limiting speed hold.

Slewing Bearings: Types, Load Curves & Selection

Slewing bearing dimensions follow no international standard, yet the light and medium series interchange across brands. Compare four-point ball against crossed roller on catalogue numbers, and size on the static limiting load diagram rather than C₀.

Bearing Cages: Materials, Types & Temperature Limits

Steel cages run to 300 °C and brass to 250 °C, but a polyamide cage has no single rating: its limit depends on the lubricant. Compare cage materials, guidance types, suffix codes, and failure modes.

Ceramic Bearings: Hybrid vs Full, and What ISO Rates

A hybrid ceramic bearing gives up load rating to buy speed, and its fatigue load limit drops further than its C does. Here is what ISO 20056 rates, what it does not, and when steel is still the right spec.

Bearing Cross Reference: How to Verify an Interchange

A cross reference chart proves a bearing fits. It does not prove it performs. How to verify an interchange across SKF, NSK, NTN, FAG and Timken using ISO 15, ISO 5753-1 and ISO 492.

Bearing Noise: Diagnose the Cause and Specify It Out

Bearing noise is measured as vibration velocity in three bands, from 50 to 10,000 Hz, under ISO 15242. See what each band reveals and the noise clause to put on the purchase order.
