Description
NSK 7006 A is a angular contact ball bearing reference, within Bearings. Request a quote for 7006 A via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The NSK A series angular contact ball bearing is a bearing designed to support radial and axial loads in a single direction. Its design with offset raceways allows angular contact between balls and raceways, which gives it a higher axial load capacity than a deep groove ball bearing. It is used in applications where precision and rigidity must be combined, such as machine tool spindles, pumps and gearboxes. At MR Accesorios Industriales we quote it on WhatsApp.
The A series designation is read together with the bore diameter number and the suffix that indicates the contact angle. For example, 7003 A, 7004 A and 7005 A correspond to single row bearings with a 30° contact angle. The final number (03, 04, 05) is related to the bore diameter: the higher the number, the larger the diameter. The letter A indicates the standard contact angle of the series. Other suffixes may indicate a polyamide cage, internal clearance or precision, but it is always advisable to confirm the complete part number when requesting a quote.
These bearings are used in industries such as metalworking, food, chemical and petrochemical. In Argentina they are commonly found in lathe and milling machine spindles, centrifugal pumps, screw compressors and speed reducers. They are also used in power transmission equipment where high rigidity and rotational precision are required, such as machine tools and measuring equipment. Their ability to support combined loads makes them suitable for tandem or paired arrangements.
To select the correct bearing, the axial and radial load, the rotational speed and the environmental conditions must be taken into account. Sealing is a key factor: if there is dust or moisture, variants with seals or shields should be chosen. Lubrication must be suitable for the temperature and speed; in high-precision applications low-friction grease is usually used. Mounting requires careful alignment and, in many cases, preload adjustment to eliminate axial clearance. It is important to follow the manufacturer's recommendations for tightening torque and internal clearance.
As for equivalents, angular contact bearings from other brands with similar designations may be interchangeable, but the dimensions and contact angle must be verified. For example, an SKF 7005 ACD/P4A bearing may replace an NSK 7005 A if the tolerances and clearance match. However, not all suffixes are equivalent: the final letters may indicate differences in cage, angle or precision. It is always advisable to request a quote with the complete part number and, if it cannot be identified, to send a photo or the main dimensions.

Frequently Asked Questions
- What does the A suffix mean in NSK bearings?
- The A suffix indicates a 30° contact angle, which is the standard for this series. This defines the axial load capacity and the rigidity of the bearing. Other suffixes may indicate additional characteristics such as cage, clearance or precision.
- How do I choose between an angular contact bearing and a deep groove ball bearing?
- If the application has a significant axial load in one direction, the angular contact bearing is more suitable because it handles that force better. If the load is mainly radial and there is little space, a deep groove ball bearing may be sufficient. The choice depends on the ratio between loads and the required precision.
- Are NSK A series bearings interchangeable with other brands?
- They may be interchangeable if the dimensions, contact angle and tolerances match. Not all suffixes are equivalent between brands. To be sure, send us the part number of the original part or the dimensions and we will indicate the compatible option.
