When radial space is tight but the load is heavy, the SKF HK series is a caged needle roller bearing built around a machined outer ring and supplied without an inner ring. Transmissions, pumps, power tools and production lines commonly rely on this design. MR Industrial Accessories LLC supplies the line and helps you match the correct part number to your equipment.

Reading the code is straightforward once you know the pattern. Take HK 0408: the bore is 4 mm and the width is 8 mm. The same logic gives HK 0509 a 5 mm bore with 9 mm width, HK 0608 a 6 mm bore with 8 mm width, and HK 0810 an 8 mm bore with 10 mm width. In each case the first pair of digits is the shaft diameter and the second pair is the bearing width. Outer diameter is determined by the full code rather than repeated in the abbreviated designation.

Typical users include automotive, metalworking, food processing and textile operations. Gearboxes, hydraulic pumps, compressors, machine tools and packaging equipment are common homes for these bearings, as are appliances and portable tools where rigidity matters and space is at a premium. Because there is no inner ring, the shaft itself becomes the raceway and must be hardened and ground.

Selection starts with three checks: shaft diameter, the width you can accommodate, and the load the position will see. A shaft that is not hardened is better served by a version with an inner ring or a bushing. Press the bearing into the housing with an interference fit and leave adequate radial clearance, since misalignment will cut service life. Grease or oil both work as lubricants, the choice depending on speed and operating temperature; speed and load limits appear on the product page.

Caged needle roller bearings from different makers can be swapped when dimensions and sealing type line up. Series from INA, NSK, NTN or Timken are among the equivalents to compare, though part numbers should not be mixed without checking tolerances and clearance. MR Industrial Accessories LLC supplies SKF and can advise on interchangeability. Confirming the machine's original part number before replacing anything is always the safer route.

Have your bearing part number, or the shaft and housing dimensions, ready and send them over by WhatsApp or email. MR Industrial Accessories LLC quotes the SKF HK series and can point you to the right option for your application, including equivalent bearings from other brands when you need an alternative.
