Needle Bearings

Needle Bearing Types We Stock & Source

From compact drawn-cup designs to heavy-duty full-complement rollers — metric and inch dimensions.

Drawn Cup Needle Roller Bearings (HK, BK, RNA Series)

Thin-wall, stamped outer cup with no machined outer ring. The most compact needle bearing design — ideal for applications with severe radial space constraints. Available open (HK) or closed-end (BK) with or without inner ring. Used in transmissions, small gearboxes, compressors, and power tools.

CST Bearing Co. is an independent bearing supplier in Santa Ana, California, sourcing needle roller bearings from every major manufacturer. Needle bearings deliver high radial load capacity in a compact cross-section — when space is tight but loads are heavy, this is the bearing type to reach for. Whether you need a drawn-cup needle roller for a compact gearbox or a heavy-duty full-complement bearing for a press, we quote fast and ship faster.

Machined-Ring Needle Roller Bearings (NA, RNA Series)

Full-Complement Needle Roller Bearings

Precision-machined inner and outer rings for tighter tolerances and higher speed capability than drawn-cup designs. Available with or without inner ring (NA vs RNA). Used in machine tools, textile machinery, printing equipment, and precision industrial applications.

Maximum number of needle rollers packed without a cage — highest possible load capacity for a given cross-section. Best for heavy loads at lower speeds. Used in press tools, hydraulic cylinders, rocker arms, and heavy-duty pivoting mechanisms.

Cam Followers & Track Rollers

Heavy-duty stud-type and yoke-type rollers built around a needle bearing core — for cam mechanisms, conveyor tracks, and packaging machinery.

Cam Followers & Track Rollers (KR, KRV Series)

Stud-type or yoke-type rollers designed to follow cam profiles or run in track systems. Heavy-duty outer ring with internal needle roller complement. Used in packaging machinery, cam mechanisms, conveyor track systems, and automated assembly equipment.

When to Specify a Needle Bearing

Needle rollers are the right call when radial space is limited but load demands are high.

• Compact cross-section — needle rollers are 3–4× longer than their diameter, packing more rolling contact area into a smaller radial envelope than ball or cylindrical roller bearings.

• High radial load capacity — the long, thin rollers distribute load over a larger contact area than comparably sized ball bearings.

• Lightweight assemblies — drawn-cup designs eliminate the need for a machined housing bore in many applications, reducing weight and complexity.

• Cost-effective for oscillating motion — full-complement designs without cages excel in oscillating or slow-rotation applications like linkages and pivot points.

Brands We Stock & Source

CST is an independent supplier — we're not beholden to any single manufacturer. We source needle bearings from every major brand:

• IKO — Japanese specialist in needle rollers, cam followers, and linear motion

• INA (Schaeffler) — German-engineered, the industry standard for drawn-cup and machined-ring needle bearings

• NTN — Reliable mid-range option with broad availability

• NSK — Japanese precision, widely used in OEM applications

• Koyo/Torrington (JTEKT) — inherited the Torrington needle bearing lines, strong in drawn-cup and machined-ring designs

• Generic / economy brands — cost-effective alternatives for less critical applications
