Needle Bearings – HK, BK, NA Series for Industrial Applications

Needle bearings are essential components in many industrial machines where compact design, high load capacity and smooth operation are required. We supply a complete range of needle bearings, including HK, BK and NA series, suitable for demanding applications in automotive, manufacturing, agricultural machinery, power tools and automation systems. Worldwide delivery is available.

Why Choose Needle Bearings?

Needle bearings use long, thin rollers to maximize load capacity while keeping the bearing size small. This design provides excellent performance in applications where space is limited, yet strength and durability are essential.

• High load-carrying capacity despite compact dimensions
• Low friction and stable operation at high speeds
• Suitable for oscillating and rotating movements
• Reliable performance in harsh industrial environments
• Wide range of sizes including open, closed and heavy-duty variants

HK, BK and NA Series Overview

HK Series – Drawn Cup Needle Bearings (Open)

The HK series is widely used in gearboxes, pumps, electric motors and power tools. These bearings are lightweight, easy to install and designed for applications with limited radial space.

BK Series – Drawn Cup Needle Bearings (Closed End)

BK bearings are similar to HK bearings but feature a closed end for axial sealing and protection. They are ideal for applications where the shaft cannot extend through the bearing.

NA Series – Needle Roller Bearings with Inner Ring

The NA series is suitable for applications requiring high precision and additional support for the shaft. These bearings often run at higher speeds and are used in heavy-duty industrial equipment.

Typical Applications

• Gearboxes and transmissions
• Automotive assemblies
• Agricultural machinery
• Hydraulic pumps and compressors
• Machine tools and CNC systems
• Power tools and small electric motors
