Decoding SKF NU 1040 M/C40NHVQ077
- NU 10Series
- Cylindrical roller bearings, NU 10 series. Series differ in outside diameter and width even when the bore is the same.
- 40Bore
- Bore 200 mm (40 × 5).
- M/C40NHVQ077Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
NU 1040 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF NU 1040 M/C40NHVQ077 measures 200 mm across the bore and 310 mm across the outside diameter; its width is 51 mm (200 x 310 x 51 mm).

SKF single row cylindrical roller bearings are built for equipment that combines heavy radial loads with high rotational speeds. Because the rings separate, mounting and inspection are simpler on gearboxes, pumps, compressors, machine tools and power transmission drives. MR Industrial Accessories LLC supplies these bearings and helps you match the right configuration to your application.
Reading the designation saves time at the counter. Take NU 1040 M/C40NHVQ077: NU means a cylindrical roller bearing with two ribs on the outer ring and none on the inner ring, so the shaft can move axially. The 1040 block is the dimension series, M identifies a machined brass cage, and C40NHVQ077 covers special tolerances, internal clearance and other execution details. Ordering the exact replacement starts with understanding each block of the code.
These bearings suit gearboxes, centrifugal pumps, screw compressors, machine tool spindles and transmission equipment, and they also appear in railway and food processing machinery where cleanliness and corrosion resistance matter. Their capacity for heavy radial loads at high speed makes them a practical choice in continuous production plants, where unplanned downtime is the main concern.
Selection depends on radial and axial load, rotation speed and the working environment. Seals or shields keep contaminants out, so sealed executions are the better route in dirty areas. Internal clearance has to match the operating temperature, and lubrication, whether grease or oil, follows speed and load. During mounting, keep the seat clean and the alignment precise, and avoid impacts that could mark the rollers or raceways.
Cross-brand interchange deserves attention. Different manufacturers may list similar designations that are not truly identical, and the basic number alone is not enough. Interchangeability comes down to main dimensions, cage type and tolerances, so the suffixes must be checked because they can change internal clearance or precision. Comparing the full specification is the safe way to replace a bearing.

Frequently asked questions
- SKF NU 1040 M/C40NHVQ077 bearing: what are its dimensions?
- SKF NU 1040 M/C40NHVQ077 measures 200 mm across the bore and 310 mm across the outside diameter; its width is 51 mm (200 x 310 x 51 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation NU 1040.
- What does the suffix M mean in an SKF bearing?
- M tells you the bearing carries a machined brass cage, a robust design for high speeds and loads. Always check the complete suffix so the configuration matches what you need.
- How do I choose between an NU and an NJ bearing?
- The ribs make the difference. NU has two ribs on the outer ring and none on the inner ring, while NJ has one rib on the inner ring. That determines how axial loads are handled in one or both directions, so tell us about your application and we can help.
- What should I take into account for mounting?
- Alignment, a clean seat and correct lubrication are the essentials. Do not strike the rollers or raceways directly. Follow the manufacturer's guidance on internal clearance and tightening torque to avoid premature failures.
