Angular contact bearings from SKF handle radial and axial loads together, in one direction. Their raceways sit at an angle, which suits setups where rigidity and running accuracy matter. MR Industrial Accessories supplies this line to maintenance and purchasing teams across the United States and Latin America, and can help you match a designation to the application.
The part number itself carries most of the selection information. Take 7018 CD/P4ADGC: the digits 7018 give the size and dimensional series, CD covers the contact angle and the internal raceway geometry, P4A sets the precision class, and DGC describes axial clearance together with mounting characteristics. Reading the code in that order is the quickest way to confirm a bearing fits the spindle or shaft it is going into.
Typical uses include machine tool spindles, high-pressure pumps, compressors, electric motors and power transmission equipment. Gearboxes and differentials in automotive work also call for this bearing type, as does rolling equipment in metallurgical plants. What these applications share is a need for accuracy and the ability to carry combined loads.
Before ordering, check the sealing arrangement, internal clearance and lubrication method. Shaft and housing must be aligned so the bearing does not pick up extra load. Use the correct mounting tools, since forcing a bearing can mark the raceways. Grease or oil both work as lubricants; the choice follows speed and operating temperature. Poor mounting practice shortens service life.
On interchangeability, a bearing from another maker can serve as a replacement when dimensions and tolerances line up. Confirm the precision class and axial clearance first. Our team can review the options and compatibilities with you.
Send the complete designation by WhatsApp or email and we will identify the correct code and prepare a quote. If you only have a drawing or an old bearing, we can suggest equivalents and help with the selection.

Frequently asked questions
- What does the CD suffix indicate in an SKF bearing?
- CD is part of the designation and refers to a defined contact angle with raceways designed for combined loads. It describes internal characteristics rather than external dimensions.
- How should I decide on axial clearance?
- It depends on the application and how the bearing is mounted. Spindles on machine tools generally call for reduced clearance, while setups exposed to thermal expansion need more. Send us the details and we can help.
- Is it possible to substitute another brand for an SKF bearing?
- Yes, provided dimensions, tolerances and precision class correspond. Check axial clearance and mounting conditions before substituting. We can advise on equivalences.
