NSK 692 X belongs to deep groove ball bearing, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 692 X and any equivalents.
Deep groove ball bearings handle both radial and axial loads. Each unit consists of an inner ring, an outer ring, a cage and one row of balls. Common applications include electric motors, pumps, fans, machine tools and transmissions. NSK's X series provides thin-section metric sizes, and the suffix indicates sealing, cage or clearance. MR Industrial Accessories helps you match the exact code to your equipment.
The X series part number combines a three- or four-digit base with an X suffix. Examples include 601 X, 602 X, 681 X, 682 X, 691 X and 692 X. The base digits specify bore, outer diameter and width. The X suffix points to a particular execution, such as a cage style, seal type or tolerance class. Always check the size table and suffix definitions to decode a code correctly.
These bearings appear in low- and medium-power electric motors, centrifugal pumps, fans, compressors, machine tools, conveyor belts and transmission equipment. They also suit low-noise, high-speed uses like household appliances, power tools and medical devices. Their rigid design works for moderate radial and axial loads in both directions.
When selecting a bearing, consider radial and axial load, speed, lubrication method and operating environment. Sealing options are open, metal shields (ZZ) or rubber seals (DDU). Pick based on contamination levels and whether you need to keep lubricant in. Radial clearance (CN, C3, C4) depends on working temperature and fit. During mounting, align the supports, avoid hitting the rings and use proper tools to prevent raceway damage.
Deep groove ball bearings from different makers are interchangeable when main dimensions and execution type match. For replacement, check the full code: base number plus sealing, cage and clearance suffixes. SKF, FAG, NTN and Koyo offer dimensional equivalents, but tolerances and capacities may differ. If unsure, send us the original part code and we will identify a compatible alternative or exact replacement.
MR Industrial Accessories supplies NSK bearings and other leading brands. For X series needs, message us on WhatsApp with the code or dimensions and we will quote promptly. We also advise on lubrication, mounting and maintenance to help extend bearing service life.

Frequently asked questions
- What does the X mean in these NSK bearing designations?
- The X is part of the suffix and denotes an execution variant. It can indicate a cage type, special sealing or a specific tolerance. Share your full code with us and we will confirm what it means for your bearing.
- How do I choose between open, ZZ and DDU bearings?
- Open bearings suit external lubrication and high speeds. ZZ metal shields guard against coarse dust. DDU rubber seals retain grease and block fine contaminants. Your choice depends on the environment and maintenance plan.
- Can I replace an NSK bearing with another brand?
- Yes, if bore, outer diameter, width and execution type match. Also check radial clearance and sealing. Send us the original code and we will tell you the compatible equivalent or exact replacement.
