The INA BK-RS series is a needle roller bushing with a lateral contact seal. It mounts directly into the housing bore and runs on a hardened, ground shaft, making it suitable for tight radial spaces where rigidity and load capacity matter. MR Industrial Accessories LLC supplies this series to customers across the United States and Latin America.
The part number tells you the main dimensions. BK means thin-walled needle roller bushing. The following digits give shaft diameter and the width of the rolling zone. The -RS suffix confirms the lateral contact seal is included. For example, in BK1012-RS, BK1414-RS or BK2018-RS, the numbers change with each size, but the family and seal type stay the same. When you request a quote, send the complete part number so we can match the exact variant.
These bushings are common in machine tools, pumps, compressors, conveyors, transmission equipment and lifting mechanisms. They are selected when radial space is limited and the shaft is already hardened and ground, because the needle rollers run directly on the shaft raceway. Joints, cams and short-travel linear guides also use them where rigidity and low inertia are needed.
Selection starts with the shaft: check diameter, tolerance, hardness and surface roughness. Then confirm the housing bore and the available width. The -RS seal keeps dust out and lubricant in, so inspect the seal lips and confirm the grease or oil type during maintenance. Press fitting or using the correct installation tools is recommended. Keep the bushing aligned with the shaft and avoid impacts on the needle rollers.
Interchange between manufacturers is based on dimensions and seal configuration, not on the commercial part number. A bushing with the same dimensions and seal type can replace another brand if tolerances and load capacity are respected. MR Industrial Accessories LLC can help you verify interchangeability for the BK-RS series. Send the part number or model you need by WhatsApp or email and our team will reply promptly with a quote or an equivalent suggestion.

Frequently asked questions
- What does the -RS suffix mean on a BK bushing?
- The -RS suffix indicates that the bushing has a lateral contact seal. This seal helps retain lubricant and limits the entry of dust and particles, which is useful in dirty environments or when relubrication intervals are long.
- Can a BK-RS bushing run directly on the shaft?
- Yes. The needle rollers run on the shaft raceway, so the shaft must be hardened, ground and have the correct hardness and roughness. If the shaft does not meet these conditions, consider a solution with an inner ring or contact us to review the application.
- How do I request a quote for an INA BK-RS bushing?
- Send us the complete part number, for example BK1414-RS, or provide the shaft and housing dimensions. With that information we can identify the correct BK-RS variant and reply promptly.
