When radial space is tight but load capacity still matters, the INA BK series needle bushing is a common choice. It is a caged needle bushing that mounts directly on the shaft and inside a housing. MR Industrial Accessories supplies this line to customers across the United States and Latin America, with technical guidance to help you pick the right part number.

The part number itself tells you the size. After the letters BK, the first two digits give the shaft diameter in millimeters, and the next two give the bushing width. So BK0408 fits a 4 mm shaft and is 8 mm wide; BK0912 fits a 9 mm shaft and is 12 mm wide. The same pattern applies to BK0509, BK0709, BK0808 and BK0910. This makes it easy to identify a size without extra tables.

These bushings appear in many industrial settings: transmissions, pumps, compressors, machine tools, packaging equipment and linear motion systems. Their compact profile works where a standard ball bearing will not fit. You also find them in automotive components such as gearboxes and steering systems, and in agricultural machinery, where they handle radial loads and moderate speeds.

To select a BK bushing, confirm the shaft diameter and tolerance, the housing diameter and tolerance, and the available width. The series can be lubricated with grease or oil; in dirty environments, consider additional sealing. Press fit is the usual mounting method, using tooling that will not damage the needles or cage. Shaft-to-housing alignment is critical, because excessive misalignment shortens service life. If you need help with internal clearance or lubrication, contact us with your equipment details.

Needle bushings are made to dimensional standards, so products from different brands can often be interchanged when dimensions and execution match. INA is a well-known name in this family, and other manufacturers offer alternatives with standardized dimensions. For a safe replacement, compare the complete part number and check the mounting tolerances. If you are unsure, send us the original part number and we will help you find a suitable option.
