The INA BK-ZW series needle roller bushing is a radial needle roller bearing shaped like a bushing, intended for direct mounting in the housing without an extra outer ring. It fits supports where radial space is tight and load capacity matters. MR Industrial Accessories supplies this INA line to customers across the United States and Latin America, with technical help to select the right code.
Reading the designation helps you identify a replacement quickly. BK means a needle roller bushing with a stamped outer ring. The digits that follow give the main dimensions. ZW shows that two retaining washers are included, one per side. So BK1622-ZW is one size, while BK2538-ZW and BK3038-ZW are others in the same family.
Typical applications include machine tools, transmission equipment, pumps, compressors, conveyors and automation systems, as well as food, textile and metalworking operations. Because no additional outer ring is needed, the housing design is simpler and the assembly lighter. MR Industrial Accessories supplies these bushings for both replacement and new projects.
Selection depends on shaft diameter, expected radial load and lubrication type. The BK-ZW series is generally mounted with an interference fit in the housing and clearance on the shaft; alignment between the two is critical to prevent premature wear. The ZW washers hold grease in and keep particles out. In very contaminated environments, consider extra sealing. Grease or oil can be used, depending on speed and operating temperature.
Equivalent needle roller bushings exist under other brands. Interchangeability depends on matching mounting dimensions and sealing type. A similar code is not enough: verify inner diameter, outer diameter and width. Send the original code and we will cross-reference it with the INA line. For combined loads or high speeds, contact us for guidance on the most suitable option.

Frequently asked questions
- What does the ZW suffix mean in an INA needle roller bushing?
- The ZW suffix means the bushing has two retaining washers, one on each side. These washers help retain lubricant and protect the interior from particles, as designed in the BK-ZW series.
- How do I determine the size of BK-ZW bushing I need?
- You need the shaft diameter, housing diameter and width. With that data or the original code from your equipment, we can identify the correct size in the BK-ZW series.
- Can a bushing from another brand replace an INA BK-ZW?
- Often yes, if the mounting dimensions and sealing type match. A similar code is not sufficient: verify the dimensions. Send the original code and we will cross-reference it with the INA line.
